The purpose of `$animateCss` is NOT + * to side-step how `$animate` and ngAnimate work, but the goal is to allow pre-existing animations or + * directives to create more complex animations that can be purely driven using CSS code. + * + * Note that only browsers that support CSS transitions and/or keyframe animations are capable of + * rendering animations triggered via `$animateCss` (bad news for IE9 and lower). + * + * ## Usage + * Once again, `$animateCss` is designed to be used inside of a registered JavaScript animation that + * is powered by ngAnimate. It is possible to use `$animateCss` directly inside of a directive, however, + * any automatic control over cancelling animations and/or preventing animations from being run on + * child elements will not be handled by Angular. For this to work as expected, please use `$animate` to + * trigger the animation and then setup a JavaScript animation that injects `$animateCss` to trigger + * the CSS animation. + * + * The example below shows how we can create a folding animation on an element using `ng-if`: + * + * ```html + * + *
+ * This element will go BOOM + *
+ * + * ``` + * + * Now we create the **JavaScript animation** that will trigger the CSS transition: + * + * ```js + * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) { + * return { + * enter: function(element, doneFn) { + * var height = element[0].offsetHeight; + * return $animateCss(element, { + * from: { height:'0px' }, + * to: { height:height + 'px' }, + * duration: 1 // one second + * }); + * } + * } + * }]); + * ``` + * + * ## More Advanced Uses + * + * `$animateCss` is the underlying code that ngAnimate uses to power **CSS-based animations** behind the scenes. Therefore CSS hooks + * like `.ng-EVENT`, `.ng-EVENT-active`, `.ng-EVENT-stagger` are all features that can be triggered using `$animateCss` via JavaScript code. + * + * This also means that just about any combination of adding classes, removing classes, setting styles, dynamically setting a keyframe animation, + * applying a hardcoded duration or delay value, changing the animation easing or applying a stagger animation are all options that work with + * `$animateCss`. The service itself is smart enough to figure out the combination of options and examine the element styling properties in order + * to provide a working animation that will run in CSS. + * + * The example below showcases a more advanced version of the `.fold-animation` from the example above: + * + * ```js + * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) { + * return { + * enter: function(element, doneFn) { + * var height = element[0].offsetHeight; + * return $animateCss(element, { + * addClass: 'red large-text pulse-twice', + * easing: 'ease-out', + * from: { height:'0px' }, + * to: { height:height + 'px' }, + * duration: 1 // one second + * }); + * } + * } + * }]); + * ``` + * + * Since we're adding/removing CSS classes then the CSS transition will also pick those up: + * + * ```css + * /* since a hardcoded duration value of 1 was provided in the JavaScript animation code, + * the CSS classes below will be transitioned despite them being defined as regular CSS classes */ + * .red { background:red; } + * .large-text { font-size:20px; } + * + * /* we can also use a keyframe animation and $animateCss will make it work alongside the transition */ + * .pulse-twice { + * animation: 0.5s pulse linear 2; + * -webkit-animation: 0.5s pulse linear 2; + * } + * + * @keyframes pulse { + * from { transform: scale(0.5); } + * to { transform: scale(1.5); } + * } + * + * @-webkit-keyframes pulse { + * from { -webkit-transform: scale(0.5); } + * to { -webkit-transform: scale(1.5); } + * } + * ``` + * + * Given this complex combination of CSS classes, styles and options, `$animateCss` will figure everything out and make the animation happen. + * + * ## How the Options are handled + * + * `$animateCss` is very versatile and intelligent when it comes to figuring out what configurations to apply to the element to ensure the animation + * works with the options provided. Say for example we were adding a class that contained a keyframe value and we wanted to also animate some inline + * styles using the `from` and `to` properties. + * + * ```js + * var animator = $animateCss(element, { + * from: { background:'red' }, + * to: { background:'blue' } + * }); + * animator.start(); + * ``` + * + * ```css + * .rotating-animation { + * animation:0.5s rotate linear; + * -webkit-animation:0.5s rotate linear; + * } + * + * @keyframes rotate { + * from { transform: rotate(0deg); } + * to { transform: rotate(360deg); } + * } + * + * @-webkit-keyframes rotate { + * from { -webkit-transform: rotate(0deg); } + * to { -webkit-transform: rotate(360deg); } + * } + * ``` + * + * The missing pieces here are that we do not have a transition set (within the CSS code nor within the `$animateCss` options) and the duration of the animation is + * going to be detected from what the keyframe styles on the CSS class are. In this event, `$animateCss` will automatically create an inline transition + * style matching the duration detected from the keyframe style (which is present in the CSS class that is being added) and then prepare both the transition + * and keyframe animations to run in parallel on the element. Then when the animation is underway the provided `from` and `to` CSS styles will be applied + * and spread across the transition and keyframe animation. + * + * ## What is returned + * + * `$animateCss` works in two stages: a preparation phase and an animation phase. Therefore when `$animateCss` is first called it will NOT actually + * start the animation. All that is going on here is that the element is being prepared for the animation (which means that the generated CSS classes are + * added and removed on the element). Once `$animateCss` is called it will return an object with the following properties: + * + * ```js + * var animator = $animateCss(element, { ... }); + * ``` + * + * Now what do the contents of our `animator` variable look like: + * + * ```js + * { + * // starts the animation + * start: Function, + * + * // ends (aborts) the animation + * end: Function + * } + * ``` + * + * To actually start the animation we need to run `animation.start()` which will then return a promise that we can hook into to detect when the animation ends. + * If we choose not to run the animation then we MUST run `animation.end()` to perform a cleanup on the element (since some CSS classes and styles may have been + * applied to the element during the preparation phase). Note that all other properties such as duration, delay, transitions and keyframes are just properties + * and that changing them will not reconfigure the parameters of the animation. + * + * ### runner.done() vs runner.then() + * It is documented that `animation.start()` will return a promise object and this is true, however, there is also an additional method available on the + * runner called `.done(callbackFn)`. The done method works the same as `.finally(callbackFn)`, however, it does **not trigger a digest to occur**. + * Therefore, for performance reasons, it's always best to use `runner.done(callback)` instead of `runner.then()`, `runner.catch()` or `runner.finally()` + * unless you really need a digest to kick off afterwards. + * + * Keep in mind that, to make this easier, ngAnimate has tweaked the JS animations API to recognize when a runner instance is returned from $animateCss + * (so there is no need to call `runner.done(doneFn)` inside of your JavaScript animation code). + * Check the {@link ngAnimate.$animateCss#usage animation code above} to see how this works. + * + * @param {DOMElement} element the element that will be animated + * @param {object} options the animation-related options that will be applied during the animation + * + * * `event` - The DOM event (e.g. enter, leave, move). When used, a generated CSS class of `ng-EVENT` and `ng-EVENT-active` will be applied + * to the element during the animation. Multiple events can be provided when spaces are used as a separator. (Note that this will not perform any DOM operation.) + * * `structural` - Indicates that the `ng-` prefix will be added to the event class. Setting to `false` or omitting will turn `ng-EVENT` and + * `ng-EVENT-active` in `EVENT` and `EVENT-active`. Unused if `event` is omitted. + * * `easing` - The CSS easing value that will be applied to the transition or keyframe animation (or both). + * * `transitionStyle` - The raw CSS transition style that will be used (e.g. `1s linear all`). + * * `keyframeStyle` - The raw CSS keyframe animation style that will be used (e.g. `1s my_animation linear`). + * * `from` - The starting CSS styles (a key/value object) that will be applied at the start of the animation. + * * `to` - The ending CSS styles (a key/value object) that will be applied across the animation via a CSS transition. + * * `addClass` - A space separated list of CSS classes that will be added to the element and spread across the animation. + * * `removeClass` - A space separated list of CSS classes that will be removed from the element and spread across the animation. + * * `duration` - A number value representing the total duration of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `0` + * is provided then the animation will be skipped entirely. + * * `delay` - A number value representing the total delay of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `true` is + * used then whatever delay value is detected from the CSS classes will be mirrored on the elements styles (e.g. by setting delay true then the style value + * of the element will be `transition-delay: DETECTED_VALUE`). Using `true` is useful when you want the CSS classes and inline styles to all share the same + * CSS delay value. + * * `stagger` - A numeric time value representing the delay between successively animated elements + * ({@link ngAnimate#css-staggering-animations Click here to learn how CSS-based staggering works in ngAnimate.}) + * * `staggerIndex` - The numeric index representing the stagger item (e.g. a value of 5 is equal to the sixth item in the stagger; therefore when a + * `stagger` option value of `0.1` is used then there will be a stagger delay of `600ms`) + * * `applyClassesEarly` - Whether or not the classes being added or removed will be used when detecting the animation. This is set by `$animate` when enter/leave/move animations are fired to ensure that the CSS classes are resolved in time. (Note that this will prevent any transitions from occurring on the classes being added and removed.) + * * `cleanupStyles` - Whether or not the provided `from` and `to` styles will be removed once + * the animation is closed. This is useful for when the styles are used purely for the sake of + * the animation and do not have a lasting visual effect on the element (e.g. a collapse and open animation). + * By default this value is set to `false`. + * + * @return {object} an object with start and end methods and details about the animation. + * + * * `start` - The method to start the animation. This will return a `Promise` when called. + * * `end` - This method will cancel the animation and remove all applied CSS classes and styles. + */ +var ONE_SECOND = 1000; +var BASE_TEN = 10; + +var ELAPSED_TIME_MAX_DECIMAL_PLACES = 3; +var CLOSING_TIME_BUFFER = 1.5; + +var DETECT_CSS_PROPERTIES = { + transitionDuration: TRANSITION_DURATION_PROP, + transitionDelay: TRANSITION_DELAY_PROP, + transitionProperty: TRANSITION_PROP + PROPERTY_KEY, + animationDuration: ANIMATION_DURATION_PROP, + animationDelay: ANIMATION_DELAY_PROP, + animationIterationCount: ANIMATION_PROP + ANIMATION_ITERATION_COUNT_KEY +}; + +var DETECT_STAGGER_CSS_PROPERTIES = { + transitionDuration: TRANSITION_DURATION_PROP, + transitionDelay: TRANSITION_DELAY_PROP, + animationDuration: ANIMATION_DURATION_PROP, + animationDelay: ANIMATION_DELAY_PROP +}; + +function getCssKeyframeDurationStyle(duration) { + return [ANIMATION_DURATION_PROP, duration + 's']; +} + +function getCssDelayStyle(delay, isKeyframeAnimation) { + var prop = isKeyframeAnimation ?

Animations are not enabled by default, however, by including `ngAnimate` the animation hooks are enabled for an Angular app. + * + *
+ * + * # Usage + * Simply put, there are two ways to make use of animations when ngAnimate is used: by using **CSS** and **JavaScript**. The former works purely based + * using CSS (by using matching CSS selectors/styles) and the latter triggers animations that are registered via `module.animation()`. For + * both CSS and JS animations the sole requirement is to have a matching `CSS class` that exists both in the registered animation and within + * the HTML element that the animation will be triggered on. + * + * ## Directive Support + * The following directives are "animation aware": + * + * | Directive | Supported Animations | + * |----------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------| + * | {@link ng.directive:ngRepeat#animations ngRepeat} | enter, leave and move | + * | {@link ngRoute.directive:ngView#animations ngView} | enter and leave | + * | {@link ng.directive:ngInclude#animations ngInclude} | enter and leave | + * | {@link ng.directive:ngSwitch#animations ngSwitch} | enter and leave | + * | {@link ng.directive:ngIf#animations ngIf} | enter and leave | + * | {@link ng.directive:ngClass#animations ngClass} | add and remove (the CSS class(es) present) | + * | {@link ng.directive:ngShow#animations ngShow} & {@link ng.directive:ngHide#animations ngHide} | add and remove (the ng-hide class value) | + * | {@link ng.directive:form#animation-hooks form} & {@link ng.directive:ngModel#animation-hooks ngModel} | add and remove (dirty, pristine, valid, invalid & all other validations) | + * | {@link module:ngMessages#animations ngMessages} | add and remove (ng-active & ng-inactive) | + * | {@link module:ngMessages#animations ngMessage} | enter and leave | + * + * (More information can be found by visiting each the documentation associated with each directive.) + * + * ## CSS-based Animations + * + * CSS-based animations with ngAnimate are unique since they require no JavaScript code at all. By using a CSS class that we reference between our HTML + * and CSS code we can create an animation that will be picked up by Angular when an the underlying directive performs an operation. + * + * The example below shows how an `enter` animation can be made possible on an element using `ng-if`: + * + * ```html + *
+ * Fade me in out + *
+ * + * + * ``` + * + * Notice the CSS class **fade**? We can now create the CSS transition code that references this class: + * + * ```css + * /* The starting CSS styles for the enter animation */ + * .fade.ng-enter { + * transition:0.5s linear all; + * opacity:0; + * } + * + * /* The finishing CSS styles for the enter animation */ + * .fade.ng-enter.ng-enter-active { + * opacity:1; + * } + * ``` + * + * The key thing to remember here is that, depending on the animation event (which each of the directives above trigger depending on what's going on) two + * generated CSS classes will be applied to the element; in the example above we have `.ng-enter` and `.ng-enter-active`. For CSS transitions, the transition + * code **must** be defined within the starting CSS class (in this case `.ng-enter`). The destination class is what the transition will animate towards. + * + * If for example we wanted to create animations for `leave` and `move` (ngRepeat triggers move) then we can do so using the same CSS naming conventions: + * + * ```css + * /* now the element will fade out before it is removed from the DOM */ + * .fade.ng-leave { + * transition:0.5s linear all; + * opacity:1; + * } + * .fade.ng-leave.ng-leave-active { + * opacity:0; + * } + * ``` + * + * We can also make use of **CSS Keyframes** by referencing the keyframe animation within the starting CSS class: + * + * ```css + * /* there is no need to define anything inside of the destination + * CSS class since the keyframe will take charge of the animation */ + * .fade.ng-leave { + * animation: my_fade_animation 0.5s linear; + * -webkit-animation: my_fade_animation 0.5s linear; + * } + * + * @keyframes my_fade_animation { + * from { opacity:1; } + * to { opacity:0; } + * } + * + * @-webkit-keyframes my_fade_animation { + * from { opacity:1; } + * to { opacity:0; } + * } + * ``` + * + * Feel free also mix transitions and keyframes together as well as any other CSS classes on the same element. + * + * ### CSS Class-based Animations + * + * Class-based animations (animations that are triggered via `ngClass`, `ngShow`, `ngHide` and some other directives) have a slightly different + * naming convention. Class-based animations are basic enough that a standard transition or keyframe can be referenced on the class being added + * and removed. + * + * For example if we wanted to do a CSS animation for `ngHide` then we place an animation on the `.ng-hide` CSS class: + * + * ```html + *
+ * Show and hide me + *
+ * + * + * + * ``` + * + * All that is going on here with ngShow/ngHide behind the scenes is the `.ng-hide` class is added/removed (when the hidden state is valid). Since + * ngShow and ngHide are animation aware then we can match up a transition and ngAnimate handles the rest. + * + * In addition the addition and removal of the CSS class, ngAnimate also provides two helper methods that we can use to further decorate the animation + * with CSS styles. + * + * ```html + *
+ * Highlight this box + *
+ * + * + * + * ``` + * + * We can also make use of CSS keyframes by placing them within the CSS classes. + * + * + * ### CSS Staggering Animations + * A Staggering animation is a collection of animations that are issued with a slight delay in between each successive operation resulting in a + * curtain-like effect. The ngAnimate module (versions >=1.2) supports staggering animations and the stagger effect can be + * performed by creating a **ng-EVENT-stagger** CSS class and attaching that class to the base CSS class used for + * the animation. The style property expected within the stagger class can either be a **transition-delay** or an + * **animation-delay** property (or both if your animation contains both transitions and keyframe animations). + * + * ```css + * .my-animation.ng-enter { + * /* standard transition code */ + * transition: 1s linear all; + * opacity:0; + * } + * .my-animation.ng-enter-stagger { + * /* this will have a 100ms delay between each successive leave animation */ + * transition-delay: 0.1s; + * + * /* As of 1.4.4, this must always be set: it signals ngAnimate + * to not accidentally inherit a delay property from another CSS class */ + * transition-duration: 0s; + * } + * .my-animation.ng-enter.ng-enter-active { + * /* standard transition styles */ + * opacity:1; + * } + * ``` + * + * Staggering animations work by default in ngRepeat (so long as the CSS class is defined). Outside of ngRepeat, to use staggering animations + * on your own, they can be triggered by firing multiple calls to the same event on $animate. However, the restrictions surrounding this + * are that each of the elements must have the same CSS className value as well as the same parent element. A stagger operation + * will also be reset if one or more animation frames have passed since the multiple calls to `$animate` were fired. + * + * The following code will issue the **ng-leave-stagger** event on the element provided: + * + * ```js + * var kids = parent.children(); + * + * $animate.leave(kids[0]); //stagger index=0 + * $animate.leave(kids[1]); //stagger index=1 + * $animate.leave(kids[2]); //stagger index=2 + * $animate.leave(kids[3]); //stagger index=3 + * $animate.leave(kids[4]); //stagger index=4 + * + * window.requestAnimationFrame(function() { + * //stagger has reset itself + * $animate.leave(kids[5]); //stagger index=0 + * $animate.leave(kids[6]); //stagger index=1 + * + * $scope.$digest(); + * }); + * ``` + * + * Stagger animations are currently only supported within CSS-defined animations. + * + * ### The `ng-animate` CSS class + * + * When ngAnimate is animating an element it will apply the `ng-animate` CSS class to the element for the duration of the animation. + * This is a temporary CSS class and it will be removed once the animation is over (for both JavaScript and CSS-based animations). + * + * Therefore, animations can be applied to an element using this temporary class directly via CSS. + * + * ```css + * .zipper.ng-animate { + * transition:0.5s linear all; + * } + * .zipper.ng-enter { + * opacity:0; + * } + * .zipper.ng-enter.ng-enter-active { + * opacity:1; + * } + * .zipper.ng-leave { + * opacity:1; + * } + * .zipper.ng-leave.ng-leave-active { + * opacity:0; + * } + * ``` + * + * (Note that the `ng-animate` CSS class is reserved and it cannot be applied on an element directly since ngAnimate will always remove + * the CSS class once an animation has completed.) + * + * + * ### The `ng-[event]-prepare` class + * + * This is a special class that can be used to prevent unwanted flickering / flash of content before + * the actual animation starts. The class is added as soon as an animation is initialized, but removed + * before the actual animation starts (after waiting for a $digest). + * It is also only added for *structural* animations (`enter`, `move`, and `leave`). + * + * In practice, flickering can appear when nesting elements with structural animations such as `ngIf` + * into elements that have class-based animations such as `ngClass`. + * + * ```html + *
+ *
+ *
+ *
+ *
+ * ``` + * + * It is possible that during the `enter` animation, the `.message` div will be briefly visible before it starts animating. + * In that case, you can add styles to the CSS that make sure the element stays hidden before the animation starts: + * + * ```css + * .message.ng-enter-prepare { + * opacity: 0; + * } + * + * ``` + * + * ## JavaScript-based Animations + * + * ngAnimate also allows for animations to be consumed by JavaScript code. The approach is similar to CSS-based animations (where there is a shared + * CSS class that is referenced in our HTML code) but in addition we need to register the JavaScript animation on the module. By making use of the + * `module.animation()` module function we can register the animation. + * + * Let's see an example of a enter/leave animation using `ngRepeat`: + * + * ```html + *
+ * {{ item }} + *
+ * ``` + * + * See the **slide** CSS class? Let's use that class to define an animation that we'll structure in our module code by using `module.animation`: + * + * ```js + * myModule.animation('.slide', [function() { + * return { + * // make note that other events (like addClass/removeClass) + * // have different function input parameters + * enter: function(element, doneFn) { + * jQuery(element).fadeIn(1000, doneFn); + * + * // remember to call doneFn so that angular + * // knows that the animation has concluded + * }, + * + * move: function(element, doneFn) { + * jQuery(element).fadeIn(1000, doneFn); + * }, + * + * leave: function(element, doneFn) { + * jQuery(element).fadeOut(1000, doneFn); + * } + * } + * }]); + * ``` + * + * The nice thing about JS-based animations is that we can inject other services and make use of advanced animation libraries such as + * greensock.js and velocity.js. + * + * If our animation code class-based (meaning that something like `ngClass`, `ngHide` and `ngShow` triggers it) then we can still define + * our animations inside of the same registered animation, however, the function input arguments are a bit different: + * + * ```html + *
+ * this box is moody + *
+ * + * + * + * ``` + * + * ```js + * myModule.animation('.colorful', [function() { + * return { + * addClass: function(element, className, doneFn) { + * // do some cool animation and call the doneFn + * }, + * removeClass: function(element, className, doneFn) { + * // do some cool animation and call the doneFn + * }, + * setClass: function(element, addedClass, removedClass, doneFn) { + * // do some cool animation and call the doneFn + * } + * } + * }]); + * ``` + * + * ## CSS + JS Animations Together + * + * AngularJS 1.4 and higher has taken steps to make the amalgamation of CSS and JS animations more flexible. However, unlike earlier versions of Angular, + * defining CSS and JS animations to work off of the same CSS class will not work anymore. Therefore the example below will only result in **JS animations taking + * charge of the animation**: + * + * ```html + *
+ * Slide in and out + *
+ * ``` + * + * ```js + * myModule.animation('.slide', [function() { + * return { + * enter: function(element, doneFn) { + * jQuery(element).slideIn(1000, doneFn); + * } + * } + * }]); + * ``` + * + * ```css + * .slide.ng-enter { + * transition:0.5s linear all; + * transform:translateY(-100px); + * } + * .slide.ng-enter.ng-enter-active { + * transform:translateY(0); + * } + * ``` + * + * Does this mean that CSS and JS animations cannot be used together? Do JS-based animations always have higher priority? We can make up for the + * lack of CSS animations by using the `$animateCss` service to trigger our own tweaked-out, CSS-based animations directly from + * our own JS-based animation code: + * + * ```js + * myModule.animation('.slide', ['$animateCss', function($animateCss) { + * return { + * enter: function(element) { +* // this will trigger `.slide.ng-enter` and `.slide.ng-enter-active`. + * return $animateCss(element, { + * event: 'enter', + * structural: true + * }); + * } + * } + * }]); + * ``` + * + * The nice thing here is that we can save bandwidth by sticking to our CSS-based animation code and we don't need to rely on a 3rd-party animation framework. + * + * The `$animateCss` service is very powerful since we can feed in all kinds of extra properties that will be evaluated and fed into a CSS transition or + * keyframe animation. For example if we wanted to animate the height of an element while adding and removing classes then we can do so by providing that + * data into `$animateCss` directly: + * + * ```js + * myModule.animation('.slide', ['$animateCss', function($animateCss) { + * return { + * enter: function(element) { + * return $animateCss(element, { + * event: 'enter', + * structural: true, + * addClass: 'maroon-setting', + * from: { height:0 }, + * to: { height: 200 } + * }); + * } + * } + * }]); + * ``` + * + * Now we can fill in the rest via our transition CSS code: + * + * ```css + * /* the transition tells ngAnimate to make the animation happen */ + * .slide.ng-enter { transition:0.5s linear all; } + * + * /* this extra CSS class will be absorbed into the transition + * since the $animateCss code is adding the class */ + * .maroon-setting { background:red; } + * ``` + * + * And `$animateCss` will figure out the rest. Just make sure to have the `done()` callback fire the `doneFn` function to signal when the animation is over. + * + * To learn more about what's possible be sure to visit the {@link ngAnimate.$animateCss $animateCss service}. + * + * ## Animation Anchoring (via `ng-animate-ref`) + * + * ngAnimate in AngularJS 1.4 comes packed with the ability to cross-animate elements between + * structural areas of an application (like views) by pairing up elements using an attribute + * called `ng-animate-ref`. + * + * Let's say for example we have two views that are managed by `ng-view` and we want to show + * that there is a relationship between two components situated in within these views. By using the + * `ng-animate-ref` attribute we can identify that the two components are paired together and we + * can then attach an animation, which is triggered when the view changes. + * + * Say for example we have the following template code: + * + * ```html + * + *
+ *
+ * + * + * + * + * + * + * + * + * ``` + * + * Now, when the view changes (once the link is clicked), ngAnimate will examine the + * HTML contents to see if there is a match reference between any components in the view + * that is leaving and the view that is entering. It will scan both the view which is being + * removed (leave) and inserted (enter) to see if there are any paired DOM elements that + * contain a matching ref value. + * + * The two images match since they share the same ref value. ngAnimate will now create a + * transport element (which is a clone of the first image element) and it will then attempt + * to animate to the position of the second image element in the next view. For the animation to + * work a special CSS class called `ng-anchor` will be added to the transported element. + * + * We can now attach a transition onto the `.banner.ng-anchor` CSS class and then + * ngAnimate will handle the entire transition for us as well as the addition and removal of + * any changes of CSS classes between the elements: + * + * ```css + * .banner.ng-anchor { + * /* this animation will last for 1 second since there are + * two phases to the animation (an `in` and an `out` phase) */ + * transition:0.5s linear all; + * } + * ``` + * + * We also **must** include animations for the views that are being entered and removed + * (otherwise anchoring wouldn't be possible since the new view would be inserted right away). + * + * ```css + * .view-animation.ng-enter, .view-animation.ng-leave { + * transition:0.5s linear all; + * position:fixed; + * left:0; + * top:0; + * width:100%; + * } + * .view-animation.ng-enter { + * transform:translateX(100%); + * } + * .view-animation.ng-leave, + * .view-animation.ng-enter.ng-enter-active { + * transform:translateX(0%); + * } + * .view-animation.ng-leave.ng-leave-active { + * transform:translateX(-100%); + * } + * ``` + * + * Now we can jump back to the anchor animation. When the animation happens, there are two stages that occur: + * an `out` and an `in` stage. The `out` stage happens first and that is when the element is animated away + * from its origin. Once that animation is over then the `in` stage occurs which animates the + * element to its destination. The reason why there are two animations is to give enough time + * for the enter animation on the new element to be ready. + * + * The example above sets up a transition for both the in and out phases, but we can also target the out or + * in phases directly via `ng-anchor-out` and `ng-anchor-in`. + * + * ```css + * .banner.ng-anchor-out { + * transition: 0.5s linear all; + * + * /* the scale will be applied during the out animation, + * but will be animated away when the in animation runs */ + * transform: scale(1.2); + * } + * + * .banner.ng-anchor-in { + * transition: 1s linear all; + * } + * ``` + * + * + * + * + * ### Anchoring Demo + * + + + Home +

The cloned element will be placed inside of the root element + * of the application (where ng-app was defined) and all of the CSS classes of the starting element will be applied. The + * element will then animate into the `out` and `in` animations and will eventually reach the coordinates and match + * the dimensions of the destination element. During the entire animation a CSS class of `.ng-animate-shim` will be applied + * to both the starting and destination elements in order to hide them from being visible (the CSS styling for the class + * is: `visibility:hidden`). Once the anchor reaches its destination then it will be removed and the destination element + * will become visible since the shim class will be removed. + * + * ### How is the morphing handled? + * + * CSS Anchoring relies on transitions and keyframes and the internal code is intelligent enough to figure out + * what CSS classes differ between the starting element and the destination element. These different CSS classes + * will be added/removed on the anchor element and a transition will be applied (the transition that is provided + * in the anchor class). Long story short, ngAnimate will figure out what classes to add and remove which will + * make the transition of the element as smooth and automatic as possible. Be sure to use simple CSS classes that + * do not rely on DOM nesting structure so that the anchor element appears the same as the starting element (since + * the cloned element is placed inside of root element which is likely close to the body element). + * + * Note that if the root element is on the `` element then the cloned node will be placed inside of body. + * + * + * ## Using $animate in your directive code + * + * So far we've explored how to feed in animations into an Angular application, but how do we trigger animations within our own directives in our application? + * By injecting the `$animate` service into our directive code, we can trigger structural and class-based hooks which can then be consumed by animations. Let's + * imagine we have a greeting box that shows and hides itself when the data changes + * + * ```html + * Hi there + * ``` + * + * ```js + * ngModule.directive('greetingBox', ['$animate', function($animate) { + * return function(scope, element, attrs) { + * attrs.$observe('active', function(value) { + * value ? $animate.addClass(element, 'on') : $animate.removeClass(element, 'on'); + * }); + * }); + * }]); + * ``` + * + * Now the `on` CSS class is added and removed on the greeting box component. Now if we add a CSS class on top of the greeting box element + * in our HTML code then we can trigger a CSS or JS animation to happen. + * + * ```css + * /* normally we would create a CSS class to reference on the element */ + * greeting-box.on { transition:0.5s linear all; background:green; color:white; } + * ``` + * + * The `$animate` service contains a variety of other methods like `enter`, `leave`, `animate` and `setClass`. To learn more about what's + * possible be sure to visit the {@link ng.$animate $animate service API page}. + * + * + * ## Callbacks and Promises + * + * When `$animate` is called it returns a promise that can be used to capture when the animation has ended. Therefore if we were to trigger + * an animation (within our directive code) then we can continue performing directive and scope related activities after the animation has + * ended by chaining onto the returned promise that animation method returns. + * + * ```js + * // somewhere within the depths of the directive + * $animate.enter(element, parent).then(function() { + * //the animation has completed + * }); + * ``` + * + * (Note that earlier versions of Angular prior to v1.4 required the promise code to be wrapped using `$scope.$apply(...)`. This is not the case + * anymore.) + * + * In addition to the animation promise, we can also make use of animation-related callbacks within our directives and controller code by registering + * an event listener using the `$animate` service. Let's say for example that an animation was triggered on our view + * routing controller to hook into that: + * + * ```js + * ngModule.controller('HomePageController', ['$animate', function($animate) { + * $animate.on('enter', ngViewElement, function(element) { + * // the animation for this route has completed + * }]); + * }]) + * ``` + * + * (Note that you will need to trigger a digest within the callback to get angular to notice any scope-related changes.) + */ + +/** + * @ngdoc service + * @name $animate + * @kind object + * + * @description + * The ngAnimate `$animate` service documentation is the same for the core `$animate` service. + * + * Click here {@link ng.$animate to learn more about animations with `$animate`}. + */ +angular.module('ngAnimate', []) + .directive('ngAnimateSwap', ngAnimateSwapDirective) + + .directive('ngAnimateChildren', $$AnimateChildrenDirective) + .factory('$$rAFScheduler', $$rAFSchedulerFactory) + + .provider('$$animateQueue', $$AnimateQueueProvider) + .provider('$$animation', $$AnimationProvider) + + .provider('$animateCss', $AnimateCssProvider) + .provider('$$animateCssDriver', $$AnimateCssDriverProvider) + + .provider('$$animateJs', $$AnimateJsProvider) + .provider('$$animateJsDriver', $$AnimateJsDriverProvider); + + +})(window, window.angular); diff --git a/www/platforms/android/assets/www/lib/angular-animate/angular-animate.min.js b/www/platforms/android/assets/www/lib/angular-animate/angular-animate.min.js new file mode 100644 index 0000000..57108b2 --- /dev/null +++ b/www/platforms/android/assets/www/lib/angular-animate/angular-animate.min.js @@ -0,0 +1,56 @@ +/* + AngularJS v1.5.3 + (c) 2010-2016 Google, Inc. http://angularjs.org + License: MIT +*/ +(function(E,w,Va){'use strict';function ya(a,b,c){if(!a)throw Ka("areq",b||"?",c||"required");return a}function za(a,b){if(!a&&!b)return"";if(!a)return b;if(!b)return a;ba(a)&&(a=a.join(" "));ba(b)&&(b=b.join(" "));return a+" "+b}function La(a){var b={};a&&(a.to||a.from)&&(b.to=a.to,b.from=a.from);return b}function V(a,b,c){var d="";a=ba(a)?a:a&&I(a)&&a.length?a.split(/\s+/):[];q(a,function(a,f){a&&0=a&&(a=h,h=0,b.push(e),e=[]);e.push(f.fn);f.children.forEach(function(a){h++;c.push(a)});a--}e.length&&b.push(e);return b}(c)}var l=[],w=Q(a);return function(s,x,v){function h(a){a=a.hasAttribute("ng-animate-ref")?[a]:a.querySelectorAll("[ng-animate-ref]");var b=[];q(a,function(a){var c=a.getAttribute("ng-animate-ref");c&&c.length&&b.push(a)});return b}function P(a){var b=[],c={};q(a,function(a,g){var d=A(a.element),k=0<=["enter","move"].indexOf(a.event),d=a.structural? +h(d):[];if(d.length){var e=k?"to":"from";q(d,function(a){var b=a.getAttribute("ng-animate-ref");c[b]=c[b]||{};c[b][e]={animationID:g,element:H(a)}})}else b.push(a)});var d={},k={};q(c,function(c,h){var e=c.from,f=c.to;if(e&&f){var m=a[e.animationID],C=a[f.animationID],n=e.animationID.toString();if(!k[n]){var D=k[n]={structural:!0,beforeStart:function(){m.beforeStart();C.beforeStart()},close:function(){m.close();C.close()},classes:y(m.classes,C.classes),from:m,to:C,anchors:[]};D.classes.length?b.push(D): +(b.push(m),b.push(C))}k[n].anchors.push({out:e.element,"in":f.element})}else e=e?e.animationID:f.animationID,f=e.toString(),d[f]||(d[f]=!0,b.push(a[e]))});return b}function y(a,b){a=a.split(" ");b=b.split(" ");for(var c=[],d=0;d=Q&&b>=L&&(H=!0,n())}function K(){function b(){if(!P){D(!1);q(y,function(a){m.style[a[0]]=a[1]});h(a,g);e.addClass(a,ga);if(p.recalculateTimingStyles){na=m.className+" "+fa;ia=w(m,na);B=v(m,na,ia);$=B.maxDelay;I=Math.max($,0);L=B.maxDuration;if(0===L){n();return}p.hasTransitions=0z.expectedEndTime)?r.cancel(z.timer):f.push(n)}K&&(l=r(c,l,!1),f[0]={timer:l,expectedEndTime:d},f.push(n),a.data("$$animateCss",f)); +if(ea.length)a.on(ea.join(" "),C);g.to&&(g.cleanupStyles&&Ga(G,m,Object.keys(g.to)),Ba(a,g))}}function c(){var b=a.data("$$animateCss");if(b){for(var d=1;d", + "license": "MIT", + "bugs": { + "url": "https://github.com/angular/angular.js/issues" + }, + "homepage": "http://angularjs.org" +} diff --git a/www/platforms/android/assets/www/lib/angular-sanitize/README.md b/www/platforms/android/assets/www/lib/angular-sanitize/README.md new file mode 100644 index 0000000..b84aaf6 --- /dev/null +++ b/www/platforms/android/assets/www/lib/angular-sanitize/README.md @@ -0,0 +1,68 @@ +# packaged angular-sanitize + +This repo is for distribution on `npm` and `bower`.

+
+
+#### Features
+
+* **$state:**
+  * allow parameters to pass unharmed ([8939d057](https://github.com/angular-ui/ui-router/commit/8939d0572ab1316e458ef016317ecff53131a822))
+    * **BREAKING CHANGE**: state parameters are no longer automatically coerced to strings, and unspecified parameter values are now set to undefined rather than null.
+  * allow prevent syncUrl on failure ([753060b9](https://github.com/angular-ui/ui-router/commit/753060b910d5d2da600a6fa0757976e401c33172))
+* **typescript:** Add typescript definitions for component builds ([521ceb3f](https://github.com/angular-ui/ui-router/commit/521ceb3fd7850646422f411921e21ce5e7d82e0f))
+* **uiSref:** extend syntax for ui-sref ([71cad3d6](https://github.com/angular-ui/ui-router/commit/71cad3d636508b5a9fe004775ad1f1adc0c80c3e))
+* **uiSrefActive:**

+    * **BREAKING CHANGE** Since ui-sref-active now activates even when child states are active you may need to swap out your ui-sref-active with ui-sref-active-eq, thought typically we think devs want the auto inheritance.
+
+  * uiSrefActiveEq: new directive with old ui-sref-active behavior
+* **$urlRouter:**
+  * defer URL change interception ([c72d8ce1](https://github.com/angular-ui/ui-router/commit/c72d8ce11916d0ac22c81b409c9e61d7048554d7))

+# Report an Issue
+
+Help us make UI-Router better! If you think you might have found a bug, or some other weirdness, start by making sure
+it hasn't already been reported. You can [search through existing issues](https://github.com/angular-ui/ui-router/search?q=wat%3F&type=Issues)
+to see if someone's reported one similar to yours.
+
+If not, then [create a plunkr](http://bit.ly/UIR-Plunk) that demonstrates the problem (try to use as little code
+as possible: the more minimalist, the faster we can debug it).
+
+Next, [create a new issue](https://github.com/angular-ui/ui-router/issues/new) that briefly explains the problem,
+and provides a bit of background as to the circumstances that triggered it. Don't forget to include the link to
+that plunkr you created!
+
+**Note**: If you're unsure how a feature is used, or are encountering some unexpected behavior that you aren't sure
+is a bug, it's best to talk it out on
+[StackOverflow](http://stackoverflow.com/questions/ask?tags=angularjs,angular-ui-router) before reporting it. This
+keeps development streamlined, and helps us focus on building great software.
+
+
+Issues only! |
+-------------|
+Please keep in mind that the issue tracker is for *issues*. Please do *not* post an issue if you need help or support. Instead, see one of the above-mentioned forums or [IRC](irc://irc.freenode.net/#angularjs). |
+
+####Purple Labels
+A purple label means that **you** need to take some further action.

+
+# Contribute
+
+**(1)** See the **[Developing](#developing)** section below, to get the development version of UI-Router up and running on your local machine.
+
+**(2)** Check out the [roadmap](https://github.com/angular-ui/ui-router/milestones) to see where the project is headed, and if your feature idea fits with where we're headed.
+
+**(3)** If you're not sure, [open an RFC](https://github.com/angular-ui/ui-router/issues/new?title=RFC:%20My%20idea) to get some feedback on your idea.
+
+**(4)** Finally, commit some code and open a pull request. Code & commits should abide by the following rules:
+
+- *Always* have test coverage for new features (or regression tests for bug fixes), and *never* break existing tests
+- Commits should represent one logical change each; if a feature goes through multiple iterations, squash your commits down to one
+- Make sure to follow the [Angular commit message format](https://github.com/angular/angular.js/blob/master/CONTRIBUTING.md#commit-message-format) so your change will appear in the changelog of the next release.
+- Changes should always respect the coding style of the project
+
+
+
+# Developing
+
+UI-Router uses grunt >= 0.4.x. Make sure to upgrade your environment and read the
+[Migration Guide](http://gruntjs.com/upgrading-from-0.3-to-0.4).
+
+Dependencies for building from source and running tests:
+
+* [grunt-cli](https://github.com/gruntjs/grunt-cli) - run: `$ npm install -g grunt-cli`
+* Then, install the development dependencies by running `$ npm install` from the project directory
+
+There are a number of targets in the gruntfile that are used to generating different builds:
+
+* `grunt`: Perform a normal build, runs jshint and karma tests
+* `grunt build`: Perform a normal build
+* `grunt dist`: Perform a clean build and generate documentation
+* `grunt dev`: Run dev server (sample app) and watch for changes, builds and runs karma tests on changes.

+
+AngularUI Router is a routing framework for [AngularJS](http://angularjs.org), which allows you to organize the
+parts of your interface into a [*state machine*](https://en.wikipedia.org/wiki/Finite-state_machine). Unlike the
+[`$route` service](http://docs.angularjs.org/api/ngRoute.$route) in the Angular ngRoute module, which is organized around URL
+routes, UI-Router is organized around [*states*](https://github.com/angular-ui/ui-router/wiki),
+which may optionally have routes, as well as other behavior, attached.
+
+States are bound to *named*, *nested* and *parallel views*, allowing you to powerfully manage your application's interface.
+
+Check out the sample app: http://angular-ui.github.io/ui-router/sample/
+
+-
+**Note:** *UI-Router is under active development. As such, while this library is well-tested, the API may change. Consider using it in production applications only if you're comfortable following a changelog and updating your usage accordingly.*
+
+
+## Get Started
+
+**(1)** Get UI-Router in one of the following ways:
+ - clone & [build](CONTRIBUTING.md#developing) this repository
+ - [download the release](http://angular-ui.github.io/ui-router/release/angular-ui-router.js) (or [minified](http://angular-ui.github.io/ui-router/release/angular-ui-router.min.js))
+ - via **[Bower](http://bower.io/)**: by running `$ bower install angular-ui-router` from your console
+ - or via **[npm](https://www.npmjs.org/)**: by running `$ npm install angular-ui-router` from your console
+ - or via **[Component](https://github.com/component/component)**: by running `$ component install angular-ui/ui-router` from your console
+
+**(2)** Include `angular-ui-router.js` (or `angular-ui-router.min.js`) in your `index.html`, after including Angular itself (For Component users: ignore this step)
+
+**(3)** Add `'ui.router'` to your main module's list of dependencies (For Component users: replace `'ui.router'` with `require('angular-ui-router')`)
+
+When you're done, your setup should look similar to the following:
+
+>
+```html
+
+
+
+    
+    
+    
+    ...
+
+
+    ...
+
+
+```
+
+### [Nested States & Views](http://plnkr.co/edit/u18KQc?p=preview)
+
+The majority of UI-Router's power is in its ability to nest states & views.
+
+**(1)** First, follow the [setup](#get-started) instructions detailed above.
+
+**(2)** Then, add a [`ui-view` directive](https://github.com/angular-ui/ui-router/wiki/Quick-Reference#ui-view) to the `` of your app.
+
+>
+```html
+
+
+    

+    
+    State 1
+    State 2
+
+```
+
+**(3)** You'll notice we also added some links with [`ui-sref` directives](https://github.com/angular-ui/ui-router/wiki/Quick-Reference#ui-sref). In addition to managing state transitions, this directive auto-generates the `href` attribute of the `` element it's attached to, if the corresponding state has a URL. Next we'll add some templates. These will plug into the `ui-view` within `index.html`. Notice that they have their own `ui-view` as well! That is the key to nesting states and views.
+
+>
+```html
+
+
State 1

+

+Show List
+

+```
+```html
+
+
State 2

+

+Show List
+

+```
+
+**(4)** Next, we'll add some child templates. *These* will get plugged into the `ui-view` of their parent state templates.
+
+>
+```html
+
+
List of State 1 Items

+
    
+  
  • {{ item }}
    • 
+

+```
+
+>
+```html
+
+
List of State 2 Things

+
    
+  
  • {{ thing }}
    • 
+

+```
+
+**(5)** Finally, we'll wire it all up with `$stateProvider`. Set up your states in the module config, as in the following:
+
+
+>
+```javascript
+myApp.config(function($stateProvider, $urlRouterProvider) {
+  //
+  // For any unmatched url, redirect to /state1
+  $urlRouterProvider.otherwise("/state1");
+  //
+  // Now set up the states
+  $stateProvider
+    .state('state1', {
+      url: "/state1",
+      templateUrl: "partials/state1.html"
+    })
+    .state('state1.list', {
+      url: "/list",
+      templateUrl: "partials/state1.list.html",
+      controller: function($scope) {
+        $scope.items = ["A", "List", "Of", "Items"];
+      }
+    })
+    .state('state2', {
+      url: "/state2",
+      templateUrl: "partials/state2.html"
+    })
+    .state('state2.list', {
+      url: "/list",
+      templateUrl: "partials/state2.list.html",
+      controller: function($scope) {
+        $scope.things = ["A", "Set", "Of", "Things"];
+      }
+    });
+});
+```
+
+**(6)** See this quick start example in action.
+>**[Go to Quick Start Plunker for Nested States & Views](http://plnkr.co/edit/u18KQc?p=preview)**
+
+**(7)** This only scratches the surface
+>**[Dive Deeper!](https://github.com/angular-ui/ui-router/wiki)**
+
+
+### [Multiple & Named Views](http://plnkr.co/edit/SDOcGS?p=preview)
+
+Another great feature is the ability to have multiple `ui-view`s view per template.
+
+**Pro Tip:** *While multiple parallel views are a powerful feature, you'll often be able to manage your
+interfaces more effectively by nesting your views, and pairing those views with nested states.*
+
+**(1)** Follow the [setup](#get-started) instructions detailed above.
+
+**(2)** Add one or more `ui-view` to your app, give them names.
+>
+```html
+
+
+    

+    

+    
+    Route 1
+    Route 2
+
+```
+
+**(3)** Set up your states in the module config:
+>
+```javascript
+myApp.config(function($stateProvider) {
+  $stateProvider
+    .state('index', {
+      url: "",
+      views: {
+        "viewA": { template: "index.viewA" },
+        "viewB": { template: "index.viewB" }
+      }
+    })
+    .state('route1', {
+      url: "/route1",
+      views: {
+        "viewA": { template: "route1.viewA" },
+        "viewB": { template: "route1.viewB" }
+      }
+    })
+    .state('route2', {
+      url: "/route2",
+      views: {
+        "viewA": { template: "route2.viewA" },
+        "viewB": { template: "route2.viewB" }
+      }
+    })
+});
+```

+ * @ngdoc object
+ * @name ui.router.util.type:UrlMatcher
+ *
+ * @description
+ * Matches URLs against patterns and extracts named parameters from the path or the search
+ * part of the URL. A URL pattern consists of a path pattern, optionally followed by '?' and a list
+ * of search parameters. Multiple search parameter names are separated by '&'. Search parameters
+ * do not influence whether or not a URL is matched, but their values are passed through into
+ * the matched parameters returned by {@link ui.router.util.type:UrlMatcher#methods_exec exec}.
+ * 
+ * Path parameter placeholders can be specified using simple colon/catch-all syntax or curly brace
+ * syntax, which optionally allows a regular expression for the parameter to be specified:
+ *
+ * * `':'` name - colon placeholder
+ * * `'*'` name - catch-all placeholder
+ * * `'{' name '}'` - curly placeholder
+ * * `'{' name ':' regexp|type '}'` - curly placeholder with regexp or type name. Should the
+ *   regexp itself contain curly braces, they must be in matched pairs or escaped with a backslash.
+ *
+ * Parameter names may contain only word characters (latin letters, digits, and underscore) and
+ * must be unique within the pattern (across both path and search parameters). For colon 
+ * placeholders or curly placeholders without an explicit regexp, a path parameter matches any
+ * number of characters other than '/'. For catch-all placeholders the path parameter matches
+ * any number of characters.
+ * 
+ * Examples:
+ * 
+ * * `'/hello/'` - Matches only if the path is exactly '/hello/'. There is no special treatment for
+ *   trailing slashes, and patterns have to match the entire path, not just a prefix.
+ * * `'/user/:id'` - Matches '/user/bob' or '/user/1234!!!' or even '/user/' but not '/user' or
+ *   '/user/bob/details'. The second path segment will be captured as the parameter 'id'.
+ * * `'/user/{id}'` - Same as the previous example, but using curly brace syntax.
+ * * `'/user/{id:[^/]*}'` - Same as the previous example.
+ * * `'/user/{id:[0-9a-fA-F]{1,8}}'` - Similar to the previous example, but only matches if the id
+ *   parameter consists of 1 to 8 hex digits.
+ * * `'/files/{path:.*}'` - Matches any URL starting with '/files/' and captures the rest of the
+ *   path into the parameter 'path'.
+ * * `'/files/*path'` - ditto.
+ * * `'/calendar/{start:date}'` - Matches "/calendar/2014-11-12" (because the pattern defined
+ *   in the built-in  `date` Type matches `2014-11-12`) and provides a Date object in $stateParams.start
+ *
+ * @param {string} pattern  The pattern to compile into a matcher.
+ * @param {Object} config  A configuration object hash:
+ * @param {Object=} parentMatcher Used to concatenate the pattern/config onto
+ *   an existing UrlMatcher
+ *
+ * * `caseInsensitive` - `true` if URL matching should be case insensitive, otherwise `false`, the default value (for backward compatibility) is `false`.
+ * * `strict` - `false` if matching against a URL with a trailing slash should be treated as equivalent to a URL without a trailing slash, the default value is `true`.
+ *
+ * @property {string} prefix  A static prefix of this pattern. The matcher guarantees that any
+ *   URL matching this matcher (i.e. any string for which {@link ui.router.util.type:UrlMatcher#methods_exec exec()} returns
+ *   non-null) will start with this prefix.
+ *
+ * @property {string} source  The pattern that was passed into the constructor
+ *
+ * @property {string} sourcePath  The path portion of the source property
+ *
+ * @property {string} sourceSearch  The search portion of the source property
+ *
+ * @property {string} regex  The constructed regex that will be used to match against the url when 
+ *   it is time to determine which url will match.
+ *
+ * @returns {Object}  New `UrlMatcher` object

+  //   ':' name
+  //   '{' name '}'
+  //   '{' name ':' regexp '}'
+  // The regular expression is somewhat complicated due to the need to allow curly braces
+  // inside the regular expression. The placeholder regexp breaks down as follows:
+  //    ([:*])([\w\[\]]+)              - classic placeholder ($1 / $2) (search version has - for snake-case)
+  //    \{([\w\[\]]+)(?:\:( ... ))?\}  - curly brace placeholder ($3) with optional regexp/type ... ($4) (search version has - for snake-case

+   *
+   * @param {string} name  The type name.

+   *        {@link ui.router.util.type:Type `Type`} for information on the values accepted.
+   * @param {Object|Function} definitionFn (optional) A function that is injected before the app

+   *        See {@link ui.router.util.type:Type `Type`} for information on the values accepted.
+   *
+   * @returns {Object}  Returns `$urlMatcherFactoryProvider`.
+   *
+   * @example
+   * This is a simple example of a custom type that encodes and decodes items from an
+   * array, using the array index as the URL-encoded value:
+   *
+   * 
+   * var list = ['John', 'Paul', 'George', 'Ringo'];
+   *
+   * $urlMatcherFactoryProvider.type('listItem', {
+   *   encode: function(item) {

+   *     return list.indexOf(item);
+   *   },

+   *     return list[parseInt(item, 10)];
+   *   },
+   *   is: function(item) {
+   *     // Ensure the item is valid by checking to see that it appears
+   *     // in the list
+   *     return list.indexOf(item) > -1;
+   *   }
+   * });

+   * $stateProvider.state('list', {
+   *   url: "/list/{item:listItem}",
+   *   controller: function($scope, $stateParams) {
+   *     console.log($stateParams.item);

+   * // ...
+   *
+   * // Changes URL to '/list/3', logs "Ringo" to the console
+   * $state.go('list', { item: "Ringo" });
+   * 

+   *
+   * This is a more complex example of a type that relies on dependency injection to
+   * interact with services, and uses the parameter name from the URL to infer how to
+   * handle encoding and decoding parameter values:
+   *
+   * 
+   * // Defines a custom type that gets a value from a service,

+   *   // Matches up services to URL parameter names
+   *   var services = {
+   *     user: Users,
+   *     post: Posts
+   *   };
+   *
+   *   return {
+   *     encode: function(object) {
+   *       // Represent the object in the URL using its unique ID
+   *       return object.id;
+   *     },
+   *     decode: function(value, key) {
+   *       // Look up the object by ID, using the parameter
+   *       // name (key) to call the correct service
+   *       return services[key].findById(value);
+   *     },
+   *     is: function(object, key) {
+   *       // Check that object is a valid dbObject
+   *       return angular.isObject(object) && object.id && services[key];
+   *     }
+   *     equals: function(a, b) {
+   *       // Check the equality of decoded objects by comparing
+   *       // their unique IDs
+   *       return a.id === b.id;
+   *     }
+   *   };

+   * @methodOf ui.router.state.$stateProvider
+   *
+   * @description
+   * Allows you to extend (carefully) or override (at your own peril) the 
+   * `stateBuilder` object used internally by `$stateProvider`. This can be used 
+   * to add custom functionality to ui-router, for example inferring templateUrl 
+   * based on the state name.
+   *
+   * When passing only a name, it returns the current (original or decorated) builder
+   * function that matches `name`.
+   *
+   * The builder functions that can be decorated are listed below. Though not all
+   * necessarily have a good use case for decoration, that is up to you to decide.
+   *
+   * In addition, users can attach custom decorators, which will generate new 
+   * properties within the state's internal definition. There is currently no clear 
+   * use-case for this beyond accessing internal states (i.e. $state.$current), 
+   * however, expect this to become increasingly relevant as we introduce additional 
+   * meta-programming features.
+   *
+   * **Warning**: Decorators should not be interdependent because the order of 
+   * execution of the builder functions in non-deterministic. Builder functions 
+   * should only be dependent on the state definition object and super function.
+   *
+   *
+   * Existing builder functions and current return values:
+   *
+   * - **parent** `{object}` - returns the parent state object.
+   * - **data** `{object}` - returns state data, including any inherited data that is not
+   *   overridden by own values (if any).
+   * - **url** `{object}` - returns a {@link ui.router.util.type:UrlMatcher UrlMatcher}
+   *   or `null`.
+   * - **navigable** `{object}` - returns closest ancestor state that has a URL (aka is 
+   *   navigable).
+   * - **params** `{object}` - returns an array of state params that are ensured to 
+   *   be a super-set of parent's params.
+   * - **views** `{object}` - returns a views object where each key is an absolute view 
+   *   name (i.e. "viewName@stateName") and each value is the config object 
+   *   (template, controller) for the view. Even when you don't use the views object 
+   *   explicitly on a state config, one is still created for you internally.
+   *   So by decorating this builder function you have access to decorating template 
+   *   and controller properties.
+   * - **ownParams** `{object}` - returns an array of params that belong to the state, 
+   *   not including any params defined by ancestor states.
+   * - **path** `{string}` - returns the full path from the root down to this state. 
+   *   Needed for state activation.

+   *
+   * @description
+   * Registers a state configuration under a given state name. The stateConfig object
+   * has the following acceptable properties.
+   *
+   * @param {string} name A unique state name, e.g. "home", "about", "contacts".
+   * To create a parent/child state use a dot, e.g. "about.sales", "home.newest".
+   * @param {object} stateConfig State configuration object.
+   * @param {string|function=} stateConfig.template
+   * 
+   *   html template as a string or a function that returns
+   *   an html template as a string which should be used by the uiView directives. This property 
+   *   takes precedence over templateUrl.
+   *   
+   *   If `template` is a function, it will be called with the following parameters:
+   *
+   *   - {array.<object>} - state parameters extracted from the current $location.path() by
+   *     applying the current state
+   *
+   * 
template:

+   * @param {string|function=} stateConfig.templateUrl
+   * 
+   *
+   *   path or function that returns a path to an html
+   *   template that should be used by uiView.
+   *   
+   *   If `templateUrl` is a function, it will be called with the following parameters:
+   *
+   *   - {array.<object>} - state parameters extracted from the current $location.path() by

+   *         return MyTemplateService.getTemplate(params.pageId);
+   *       }

+   *
+   * @param {string|function=} stateConfig.controller
+   * 
+   *
+   *  Controller fn that should be associated with newly
+   *   related scope or the name of a registered controller if passed as a string.
+   *   Optionally, the ControllerAs may be declared here.
+   * 
controller: "MyRegisteredController"

controller:
+   *     "MyRegisteredController as fooCtrl"}

+   * 
controller: function($scope, MyService) {
+   *     $scope.data = MyService.getData(); }

+   *
+   * @param {function=} stateConfig.controllerProvider
+   * 
+   *
+   * Injectable provider function that returns the actual controller or string.
+   * 
controllerProvider:

+   *     if (MyResolveData.foo)
+   *       return "FooCtrl"

+   *
+   * @param {string=} stateConfig.controllerAs
+   * 
+   * 
+   * A controller alias name. If present the controller will be
+   *   published to scope under the controllerAs name.
+   * 
controllerAs: "myCtrl"

+   *
+   * @param {object=} stateConfig.resolve
+   * 
+   *
+   * An optional map<string, function> of dependencies which
+   *   should be injected into the controller. If any of these dependencies are promises, 
+   *   the router will wait for them all to be resolved before the controller is instantiated.
+   *   If all the promises are resolved successfully, the $stateChangeSuccess event is fired
+   *   and the values of the resolved promises are injected into any controllers that reference them.
+   *   If any  of the promises are rejected the $stateChangeError event is fired.
+   *
+   *   The map object is:
+   *   
+   *   - key - {string}: name of dependency to be injected into controller
+   *   - factory - {string|function}: If string then it is alias for service. Otherwise if function, 
+   *     it is injected and return value it treated as dependency. If result is a promise, it is 
+   *     resolved before its value is injected into controller.
+   *

+   *       }
+   *     }

+   *
+   * @param {string=} stateConfig.url
+   * 
+   *
+   *   A url fragment with optional parameters. When a state is navigated or
+   *   transitioned to, the `$stateParams` service will be populated with any 
+   *   parameters that were passed.
+   *
+   * examples:
+   * 
url: "/home"
+   * url: "/users/:userid"
+   * url: "/books/{bookid:[a-zA-Z_-]}"
+   * url: "/books/{categoryid:int}"
+   * url: "/books/{publishername:string}/{categoryid:int}"
+   * url: "/messages?before&after"
+   * url: "/messages?{before:date}&{after:date}"

+   * url: "/messages/:mailboxid?{before:date}&{after:date}"
+   *
+   * @param {object=} stateConfig.views
+   * 
+   * an optional map<string, object> which defined multiple views, or targets views
+   * manually/explicitly.
+   *
+   * Examples:
+   *
+   * Targets three named `ui-view`s in the parent state's template
+   * 
views: {
+   *     header: {
+   *       controller: "headerCtrl",
+   *       templateUrl: "header.html"
+   *     }, body: {
+   *       controller: "bodyCtrl",
+   *       templateUrl: "body.html"
+   *     }, footer: {
+   *       controller: "footCtrl",
+   *       templateUrl: "footer.html"
+   *     }
+   *   }

+   *
+   * Targets named `ui-view="header"` from grandparent state 'top''s template, and named `ui-view="body" from parent state's template.
+   * 
views: {
+   *     'header@top': {
+   *       controller: "msgHeaderCtrl",
+   *       templateUrl: "msgHeader.html"
+   *     }, 'body': {
+   *       controller: "messagesCtrl",
+   *       templateUrl: "messages.html"
+   *     }
+   *   }

+   *
+   * @param {boolean=} [stateConfig.abstract=false]
+   * 
+   * An abstract state will never be directly activated,
+   *   but can provide inherited properties to its common children states.
+   * 
abstract: true

+   *
+   * @param {function=} stateConfig.onEnter
+   * 
+   *
+   * Callback function for when a state is entered. Good way
+   *   to trigger an action or dispatch an event, such as opening a dialog.
+   * If minifying your scripts, make sure to explictly annotate this function,
+   * because it won't be automatically annotated by your build tools.
+   *
+   * 
onEnter: function(MyService, $stateParams) {
+   *     MyService.foo($stateParams.myParam);
+   * }

+   *
+   * @param {function=} stateConfig.onExit
+   * 
+   *
+   * Callback function for when a state is exited. Good way to
+   *   trigger an action or dispatch an event, such as opening a dialog.
+   * If minifying your scripts, make sure to explictly annotate this function,
+   * because it won't be automatically annotated by your build tools.
+   *
+   * 
onExit: function(MyService, $stateParams) {
+   *     MyService.cleanup($stateParams.myParam);
+   * }

+   *
+   * @param {boolean=} [stateConfig.reloadOnSearch=true]
+   * 
+   *
+   * If `false`, will not retrigger the same state
+   *   just because a search/query parameter has changed (via $location.search() or $location.hash()). 
+   *   Useful for when you'd like to modify $location.search() without triggering a reload.
+   * 
reloadOnSearch: false

+   *
+   * @param {object=} stateConfig.data
+   * 
+   *
+   * Arbitrary data object, useful for custom configuration.  The parent state's `data` is
+   *   prototypally inherited.  In other words, adding a data property to a state adds it to
+   *   the entire subtree via prototypal inheritance.
+   *
+   * 
data: {
+   *     requiredRole: 'foo'
+   * } 

+   *
+   * @param {object=} stateConfig.params
+   * 
+   *
+   * A map which optionally configures parameters declared in the `url`, or
+   *   defines additional non-url parameters.  For each parameter being
+   *   configured, add a configuration object keyed to the name of the parameter.
+   *
+   *   Each parameter configuration object may contain the following properties:
+   *
+   *   - ** value ** - {object|function=}: specifies the default value for this
+   *     parameter.  This implicitly sets this parameter as optional.
+   *
+   *     When UI-Router routes to a state and no value is
+   *     specified for this parameter in the URL or transition, the
+   *     default value will be used instead.  If `value` is a function,
+   *     it will be injected and invoked, and the return value used.
+   *
+   *     *Note*: `undefined` is treated as "no default value" while `null`
+   *     is treated as "the default value is `null`".
+   *
+   *     *Shorthand*: If you only need to configure the default value of the
+   *     parameter, you may use a shorthand syntax.   In the **`params`**
+   *     map, instead mapping the param name to a full parameter configuration
+   *     object, simply set map it to the default parameter value, e.g.:
+   *
+   * 
// define a parameter's default value
+   * params: {
+   *     param1: { value: "defaultValue" }
+   * }
+   * // shorthand default values
+   * params: {
+   *     param1: "defaultValue",
+   *     param2: "param2Default"
+   * }

+   *
+   *   - ** array ** - {boolean=}: *(default: false)* If true, the param value will be
+   *     treated as an array of values.  If you specified a Type, the value will be
+   *     treated as an array of the specified Type.  Note: query parameter values
+   *     default to a special `"auto"` mode.
+   *
+   *     For query parameters in `"auto"` mode, if multiple  values for a single parameter
+   *     are present in the URL (e.g.: `/foo?bar=1&bar=2&bar=3`) then the values
+   *     are mapped to an array (e.g.: `{ foo: [ '1', '2', '3' ] }`).  However, if
+   *     only one value is present (e.g.: `/foo?bar=1`) then the value is treated as single
+   *     value (e.g.: `{ foo: '1' }`).
+   *
+   * 
params: {
+   *     param1: { array: true }
+   * }

+   *
+   *   - ** squash ** - {bool|string=}: `squash` configures how a default parameter value is represented in the URL when
+   *     the current parameter value is the same as the default value. If `squash` is not set, it uses the
+   *     configured default squash policy.
+   *     (See {@link ui.router.util.$urlMatcherFactory#methods_defaultSquashPolicy `defaultSquashPolicy()`})
+   *
+   *   There are three squash settings:
+   *
+   *     - false: The parameter's default value is not squashed.  It is encoded and included in the URL
+   *     - true: The parameter's default value is omitted from the URL.  If the parameter is preceeded and followed
+   *       by slashes in the state's `url` declaration, then one of those slashes are omitted.
+   *       This can allow for cleaner looking URLs.
+   *     - `""`: The parameter's default value is replaced with an arbitrary placeholder of  your choice.
+   *
+   * 
params: {
+   *     param1: {
+   *       value: "defaultId",
+   *       squash: true
+   * } }
+   * // squash "defaultValue" to "~"
+   * params: {
+   *     param1: {
+   *       value: "defaultValue",
+   *       squash: "~"
+   * } }
+   * 

+   *
+   *
+   * @example
+   * 
+   * // Some state name examples
+   *
+   * // stateName can be a single top-level name (must be unique).
+   * $stateProvider.state("home", {});
+   *
+   * // Or it can be a nested state name. This state is a child of the
+   * // above "home" state.
+   * $stateProvider.state("home.newest", {});
+   *
+   * // Nest states as deeply as needed.
+   * $stateProvider.state("home.newest.abc.xyz.inception", {});
+   *
+   * // state() returns $stateProvider, so you can chain state declarations.
+   * $stateProvider
+   *   .state("home", {})
+   *   .state("about", {})
+   *   .state("contacts", {});

+     * - `$state.go('^')` - will go to a parent state
+     * - `$state.go('^.sibling')` - will go to a sibling state
+     * - `$state.go('.child.grandchild')` - will go to grandchild state
+     *
+     * @param {object=} params A map of the parameters that will be sent to the state, 
+     * will populate $stateParams. Any parameters that are not specified will be inherited from currently 
+     * defined parameters. This allows, for example, going to a sibling state that shares parameters
+     * specified in a parent state. Parameter inheritance only works between common ancestor states, I.e.
+     * transitioning to a sibling will get you the parameters for all parents, transitioning to a child
+     * will get you all current parameters, etc.
+     * @param {object=} options Options object. The options are:
+     *
+     * - **`location`** - {boolean=true|string=} - If `true` will update the url in the location bar, if `false`
+     *    will not. If string, must be `"replace"`, which will update url and also replace last history record.
+     * - **`inherit`** - {boolean=true}, If `true` will inherit url parameters from current url.
+     * - **`relative`** - {object=$state.$current}, When transitioning with relative path (e.g '^'), 
+     *    defines which state to be relative from.
+     * - **`notify`** - {boolean=true}, If `true` will broadcast $stateChangeStart and $stateChangeSuccess events.
+     * - **`reload`** (v0.2.5) - {boolean=false}, If `true` will force transition even if the state or params 
+     *    have not changed, aka a reload of the same state. It differs from reloadOnSearch because you'd
+     *    use this when you want to force a reload when *everything* is the same, including search params.
+     *
+     * @returns {promise} A promise representing the state of the new transition.
+     *
+     * Possible success values:
+     *
+     * - $state.current
+     *
+     * 
Possible rejection values:
+     *
+     * - 'transition superseded' - when a newer transition has been started after this one
+     * - 'transition prevented' - when `event.preventDefault()` has been called in a `$stateChangeStart` listener
+     * - 'transition aborted' - when `event.preventDefault()` has been called in a `$stateNotFound` listener or
+     *   when a `$stateNotFound` `event.retry` promise errors.
+     * - 'transition failed' - when a state has been unsuccessfully found after 2 tries.

+ *
+ * @description
+ * The ui-view directive tells $state where to place your templates.
+ *
+ * @param {string=} name A view name. The name should be unique amongst the other views in the
+ * same state. You can have views of the same name that live in different states.
+ *
+ * @param {string=} autoscroll It allows you to set the scroll behavior of the browser window
+ * when a view is populated. By default, $anchorScroll is overridden by ui-router's custom scroll
+ * service, {@link ui.router.state.$uiViewScroll}. This custom service let's you
+ * scroll ui-view elements into view when they are populated during a state activation.
+ *
+ * *Note: To revert back to old [`$anchorScroll`](http://docs.angularjs.org/api/ng.$anchorScroll)
+ * functionality, call `$uiViewScrollProvider.useAnchorScroll()`.*
+ *
+ * @param {string=} onload Expression to evaluate whenever the view updates.
+ * 
+ * @example
+ * A view can be unnamed or named. 
+ * 
+ * 
+ * 
 
+ * 
+ * 
+ * 

+ * 

+ *
+ * You can only have one unnamed view within any template (or root html). If you are only using a 
+ * single view and it is unnamed then you can populate it like so:
+ * 
+ * 
 
+ * $stateProvider.state("home", {
+ *   template: "
HELLO!
"
+ * })
+ * 

+ * 
+ * The above is a convenient shortcut equivalent to specifying your view explicitly with the {@link ui.router.state.$stateProvider#views `views`}
+ * config property, by name, in this case an empty name:
+ * 
+ * $stateProvider.state("home", {
+ *   views: {
+ *     "": {
+ *       template: "
HELLO!
"
+ *     }
+ *   }    
+ * })
+ * 

+ * 
+ * But typically you'll only use the views property if you name your view or have more than one view 
+ * in the same template. There's not really a compelling reason to name a view if its the only one, 
+ * but you could if you wanted, like so:
+ * 
+ * 

+ * 
 
+ * 
+ * $stateProvider.state("home", {
+ *   views: {
+ *     "main": {
+ *       template: "
HELLO!
"
+ *     }
+ *   }    
+ * })
+ * 

+ * 
+ * Really though, you'll use views to set up multiple views:
+ * 
+ * 

+ * 
 
+ * 
 
+ * 

+ * 
+ * 
+ * $stateProvider.state("home", {
+ *   views: {
+ *     "": {
+ *       template: "
HELLO!
"
+ *     },
+ *     "chart": {
+ *       template: ""
+ *     },
+ *     "data": {
+ *       template: ""
+ *     }
+ *   }    
+ * })
+ * 

+ *
+ * Examples for `autoscroll`:
+ *
+ * 
+ * 
+ * 
+ *
+ * 
+ * 
+ *

+ * @description
+ * A directive that binds a link (`` tag) to a state. If the state has an associated 
+ * URL, the directive will automatically generate & update the `href` attribute via 
+ * the {@link ui.router.state.$state#methods_href $state.href()} method. Clicking 
+ * the link will trigger a state transition with optional parameters. 
+ *
+ * Also middle-clicking, right-clicking, and ctrl-clicking on the link will be 
+ * handled natively by the browser.
+ *
+ * You can also use relative state paths within ui-sref, just like the relative 
+ * paths passed to `$state.go()`. You just need to be aware that the path is relative
+ * to the state that the link lives in, in other words the state that loaded the 
+ * template containing the link.
+ *
+ * You can specify options to pass to {@link ui.router.state.$state#go $state.go()}
+ * using the `ui-sref-opts` attribute. Options are restricted to `location`, `inherit`,
+ * and `reload`.
+ *
+ * @example
+ * Here's an example of how you'd use ui-sref and how it would compile. If you have the 
+ * following template:
+ * 
+ * Home | About | Next page
+ * 
+ * 
+ * 

+ * 
+ * Then the compiled html would be (assuming Html5Mode is off and current state is contacts):
+ * 
+ * Home | About | Next page
+ * 
+ * 
    
+ *

+ *
+ * @requires ui.router.state.$state
+ * @requires ui.router.state.$stateParams
+ * @requires $interpolate
+ *
+ * @restrict A
+ *
+ * @description
+ * A directive working alongside ui-sref to add classes to an element when the
+ * related ui-sref directive's state is active, and removing them when it is inactive.
+ * The primary use-case is to simplify the special appearance of navigation menus
+ * relying on `ui-sref`, by having the "active" state's menu button appear different,
+ * distinguishing it from the inactive menu items.
+ *
+ * ui-sref-active can live on the same element as ui-sref or on a parent element. The first
+ * ui-sref-active found at the same level or above the ui-sref will be used.
+ *
+ * Will activate when the ui-sref's target state or any child state is active. If you
+ * need to activate only when the ui-sref target state is active and *not* any of
+ * it's children, then you will use
+ * {@link ui.router.state.directive:ui-sref-active-eq ui-sref-active-eq}
+ *
+ * @example
+ * Given the following template:
+ * 
+ * 
+ * 

+ *
+ *
+ * When the app state is "app.user" (or any children states), and contains the state parameter "user" with value "bilbobaggins",
+ * the resulting HTML will appear as (note the 'active' class):
+ * 
+ * 
+ * 

+ *
+ * The class name is interpolated **once** during the directives link time (any further changes to the
+ * interpolated value are ignored).
+ *
+ * Multiple classes may be specified in a space-separated format:
+ * 
+ *

+   * @ngdoc function
+   * @name ui.router.state.$stateProvider#decorator
+   * @methodOf ui.router.state.$stateProvider
+   *
+   * @description
+   * Allows you to extend (carefully) or override (at your own peril) the 
+   * `stateBuilder` object used internally by `$stateProvider`. This can be used 
+   * to add custom functionality to ui-router, for example inferring templateUrl 
+   * based on the state name.
+   *
+   * When passing only a name, it returns the current (original or decorated) builder
+   * function that matches `name`.
+   *
+   * The builder functions that can be decorated are listed below. Though not all
+   * necessarily have a good use case for decoration, that is up to you to decide.
+   *
+   * In addition, users can attach custom decorators, which will generate new 
+   * properties within the state's internal definition. There is currently no clear 
+   * use-case for this beyond accessing internal states (i.e. $state.$current), 
+   * however, expect this to become increasingly relevant as we introduce additional 
+   * meta-programming features.
+   *
+   * **Warning**: Decorators should not be interdependent because the order of 
+   * execution of the builder functions in non-deterministic. Builder functions 
+   * should only be dependent on the state definition object and super function.
+   *
+   *
+   * Existing builder functions and current return values:
+   *
+   * - **parent** `{object}` - returns the parent state object.
+   * - **data** `{object}` - returns state data, including any inherited data that is not
+   *   overridden by own values (if any).
+   * - **url** `{object}` - returns a {@link ui.router.util.type:UrlMatcher UrlMatcher}
+   *   or `null`.
+   * - **navigable** `{object}` - returns closest ancestor state that has a URL (aka is 
+   *   navigable).
+   * - **params** `{object}` - returns an array of state params that are ensured to 
+   *   be a super-set of parent's params.
+   * - **views** `{object}` - returns a views object where each key is an absolute view 
+   *   name (i.e. "viewName@stateName") and each value is the config object 
+   *   (template, controller) for the view. Even when you don't use the views object 
+   *   explicitly on a state config, one is still created for you internally.
+   *   So by decorating this builder function you have access to decorating template 
+   *   and controller properties.
+   * - **ownParams** `{object}` - returns an array of params that belong to the state, 
+   *   not including any params defined by ancestor states.
+   * - **path** `{string}` - returns the full path from the root down to this state. 
+   *   Needed for state activation.
+   * - **includes** `{object}` - returns an object that includes every state that 
+   *   would pass a `$state.includes()` test.
+   *
+   * @example
+   * 
+   * // Override the internal 'views' builder with a function that takes the state
+   * // definition, and a reference to the internal function being overridden:
+   * $stateProvider.decorator('views', function (state, parent) {
+   *   var result = {},
+   *       views = parent(state);
+   *
+   *   angular.forEach(views, function (config, name) {
+   *     var autoName = (state.name + '.' + name).replace('.', '/');
+   *     config.templateUrl = config.templateUrl || '/partials/' + autoName + '.html';
+   *     result[name] = config;
+   *   });
+   *   return result;
+   * });
+   *
+   * $stateProvider.state('home', {
+   *   views: {
+   *     'contact.list': { controller: 'ListController' },
+   *     'contact.item': { controller: 'ItemController' }
+   *   }
+   * });
+   *
+   * // ...
+   *
+   * $state.go('home');
+   * // Auto-populates list and item views with /partials/home/contact/list.html,
+   * // and /partials/home/contact/item.html, respectively.

+   *   
+   *   If `templateUrl` is a function, it will be called with the following parameters:

+   *
+   * @param {string|function=} stateConfig.controller
+   * 
+   *
+   *  Controller fn that should be associated with newly
+   *   related scope or the name of a registered controller if passed as a string.
+   *   Optionally, the ControllerAs may be declared here.
+   * 
controller: "MyRegisteredController"

controllerAs: "myCtrl"

+   *
+   * @param {object=} stateConfig.resolve
+   * 
+   *
+   * An optional map<string, function> of dependencies which
+   *   should be injected into the controller. If any of these dependencies are promises, 
+   *   the router will wait for them all to be resolved before the controller is instantiated.
+   *   If all the promises are resolved successfully, the $stateChangeSuccess event is fired
+   *   and the values of the resolved promises are injected into any controllers that reference them.
+   *   If any  of the promises are rejected the $stateChangeError event is fired.
+   *
+   *   The map object is:
+   *   
+   *   - key - {string}: name of dependency to be injected into controller
+   *   - factory - {string|function}: If string then it is alias for service. Otherwise if function, 
+   *     it is injected and return value it treated as dependency. If result is a promise, it is

+   *     }

+   *
+   * @param {string=} stateConfig.url
+   * 
+   *
+   *   A url fragment with optional parameters. When a state is navigated or
+   *   transitioned to, the `$stateParams` service will be populated with any 
+   *   parameters that were passed.
+   *
+   * examples:

+   * url: "/books/{bookid:[a-zA-Z_-]}"
+   * url: "/books/{categoryid:int}"

+   * url: "/messages/:mailboxid?{before:date}&{after:date}"
+   *
+   * @param {object=} stateConfig.views
+   * 
+   * an optional map<string, object> which defined multiple views, or targets views
+   * manually/explicitly.
+   *
+   * Examples:
+   *
+   * Targets three named `ui-view`s in the parent state's template
+   * 
views: {
+   *     header: {
+   *       controller: "headerCtrl",
+   *       templateUrl: "header.html"
+   *     }, body: {
+   *       controller: "bodyCtrl",
+   *       templateUrl: "body.html"
+   *     }, footer: {
+   *       controller: "footCtrl",
+   *       templateUrl: "footer.html"
+   *     }
+   *   }

+   *
+   * Targets named `ui-view="header"` from grandparent state 'top''s template, and named `ui-view="body" from parent state's template.
+   * 
views: {
+   *     'header@top': {
+   *       controller: "msgHeaderCtrl",
+   *       templateUrl: "msgHeader.html"
+   *     }, 'body': {
+   *       controller: "messagesCtrl",
+   *       templateUrl: "messages.html"
+   *     }
+   *   }

+   *
+   * @param {boolean=} [stateConfig.abstract=false]
+   * 
+   * An abstract state will never be directly activated,
+   *   but can provide inherited properties to its common children states.
+   * 
abstract: true

+   *
+   * @param {function=} stateConfig.onEnter
+   * 
+   *
+   * Callback function for when a state is entered. Good way
+   *   to trigger an action or dispatch an event, such as opening a dialog.
+   * If minifying your scripts, make sure to explictly annotate this function,
+   * because it won't be automatically annotated by your build tools.
+   *
+   * 
onEnter: function(MyService, $stateParams) {
+   *     MyService.foo($stateParams.myParam);
+   * }

+   *
+   * @param {function=} stateConfig.onExit
+   * 
+   *
+   * Callback function for when a state is exited. Good way to
+   *   trigger an action or dispatch an event, such as opening a dialog.
+   * If minifying your scripts, make sure to explictly annotate this function,
+   * because it won't be automatically annotated by your build tools.
+   *
+   * 
onExit: function(MyService, $stateParams) {
+   *     MyService.cleanup($stateParams.myParam);
+   * }

+   *
+   * @param {boolean=} [stateConfig.reloadOnSearch=true]
+   * 
+   *
+   * If `false`, will not retrigger the same state
+   *   just because a search/query parameter has changed (via $location.search() or $location.hash()). 
+   *   Useful for when you'd like to modify $location.search() without triggering a reload.
+   * 
reloadOnSearch: false

+   *
+   * @param {object=} stateConfig.data
+   * 
+   *
+   * Arbitrary data object, useful for custom configuration.  The parent state's `data` is
+   *   prototypally inherited.  In other words, adding a data property to a state adds it to
+   *   the entire subtree via prototypal inheritance.
+   *
+   * 
data: {
+   *     requiredRole: 'foo'
+   * } 

+   *
+   * @param {object=} stateConfig.params
+   * 
+   *
+   * A map which optionally configures parameters declared in the `url`, or
+   *   defines additional non-url parameters.  For each parameter being
+   *   configured, add a configuration object keyed to the name of the parameter.
+   *
+   *   Each parameter configuration object may contain the following properties:
+   *
+   *   - ** value ** - {object|function=}: specifies the default value for this
+   *     parameter.  This implicitly sets this parameter as optional.
+   *
+   *     When UI-Router routes to a state and no value is
+   *     specified for this parameter in the URL or transition, the
+   *     default value will be used instead.  If `value` is a function,
+   *     it will be injected and invoked, and the return value used.
+   *
+   *     *Note*: `undefined` is treated as "no default value" while `null`
+   *     is treated as "the default value is `null`".
+   *
+   *     *Shorthand*: If you only need to configure the default value of the
+   *     parameter, you may use a shorthand syntax.   In the **`params`**
+   *     map, instead mapping the param name to a full parameter configuration
+   *     object, simply set map it to the default parameter value, e.g.:
+   *
+   * 
// define a parameter's default value
+   * params: {
+   *     param1: { value: "defaultValue" }
+   * }
+   * // shorthand default values
+   * params: {
+   *     param1: "defaultValue",
+   *     param2: "param2Default"
+   * }

+   *
+   *   - ** array ** - {boolean=}: *(default: false)* If true, the param value will be
+   *     treated as an array of values.  If you specified a Type, the value will be
+   *     treated as an array of the specified Type.  Note: query parameter values
+   *     default to a special `"auto"` mode.
+   *
+   *     For query parameters in `"auto"` mode, if multiple  values for a single parameter
+   *     are present in the URL (e.g.: `/foo?bar=1&bar=2&bar=3`) then the values
+   *     are mapped to an array (e.g.: `{ foo: [ '1', '2', '3' ] }`).  However, if
+   *     only one value is present (e.g.: `/foo?bar=1`) then the value is treated as single
+   *     value (e.g.: `{ foo: '1' }`).
+   *
+   * 
params: {
+   *     param1: { array: true }
+   * }

+   *
+   *   - ** squash ** - {bool|string=}: `squash` configures how a default parameter value is represented in the URL when
+   *     the current parameter value is the same as the default value. If `squash` is not set, it uses the
+   *     configured default squash policy.
+   *     (See {@link ui.router.util.$urlMatcherFactory#methods_defaultSquashPolicy `defaultSquashPolicy()`})
+   *
+   *   There are three squash settings:
+   *
+   *     - false: The parameter's default value is not squashed.  It is encoded and included in the URL
+   *     - true: The parameter's default value is omitted from the URL.  If the parameter is preceeded and followed
+   *       by slashes in the state's `url` declaration, then one of those slashes are omitted.
+   *       This can allow for cleaner looking URLs.
+   *     - `""`: The parameter's default value is replaced with an arbitrary placeholder of  your choice.
+   *
+   * 
params: {
+   *     param1: {
+   *       value: "defaultId",
+   *       squash: true
+   * } }
+   * // squash "defaultValue" to "~"
+   * params: {
+   *     param1: {
+   *       value: "defaultValue",
+   *       squash: "~"
+   * } }
+   * 

+   *
+   *
+   * @example
+   * 
+   * // Some state name examples
+   *
+   * // stateName can be a single top-level name (must be unique).
+   * $stateProvider.state("home", {});
+   *
+   * // Or it can be a nested state name. This state is a child of the
+   * // above "home" state.
+   * $stateProvider.state("home.newest", {});
+   *
+   * // Nest states as deeply as needed.
+   * $stateProvider.state("home.newest.abc.xyz.inception", {});
+   *
+   * // state() returns $stateProvider, so you can chain state declarations.
+   * $stateProvider
+   *   .state("home", {})
+   *   .state("about", {})
+   *   .state("contacts", {});

+     * @methodOf ui.router.state.$state
+     *
+     * @description
+     * Convenience method for transitioning to a new state. `$state.go` calls 
+     * `$state.transitionTo` internally but automatically sets options to 
+     * `{ location: true, inherit: true, relative: $state.$current, notify: true }`. 
+     * This allows you to easily use an absolute or relative to path and specify 
+     * only the parameters you'd like to update (while letting unspecified parameters 
+     * inherit from the currently active ancestor states).
+     *
+     * @example
+     * 
+     * var app = angular.module('app', ['ui.router']);
+     *
+     * app.controller('ctrl', function ($scope, $state) {
+     *   $scope.changeState = function () {
+     *     $state.go('contact.detail');
+     *   };
+     * });
+     * 

+     * 
+     *
+     * @param {string} to Absolute state name or relative state path. Some examples:
+     *
+     * - `$state.go('contact.detail')` - will go to the `contact.detail` state
+     * - `$state.go('^')` - will go to a parent state
+     * - `$state.go('^.sibling')` - will go to a sibling state
+     * - `$state.go('.child.grandchild')` - will go to grandchild state
+     *
+     * @param {object=} params A map of the parameters that will be sent to the state, 
+     * will populate $stateParams. Any parameters that are not specified will be inherited from currently 
+     * defined parameters. This allows, for example, going to a sibling state that shares parameters
+     * specified in a parent state. Parameter inheritance only works between common ancestor states, I.e.
+     * transitioning to a sibling will get you the parameters for all parents, transitioning to a child
+     * will get you all current parameters, etc.
+     * @param {object=} options Options object. The options are:
+     *
+     * - **`location`** - {boolean=true|string=} - If `true` will update the url in the location bar, if `false`
+     *    will not. If string, must be `"replace"`, which will update url and also replace last history record.
+     * - **`inherit`** - {boolean=true}, If `true` will inherit url parameters from current url.
+     * - **`relative`** - {object=$state.$current}, When transitioning with relative path (e.g '^'), 
+     *    defines which state to be relative from.
+     * - **`notify`** - {boolean=true}, If `true` will broadcast $stateChangeStart and $stateChangeSuccess events.
+     * - **`reload`** (v0.2.5) - {boolean=false}, If `true` will force transition even if the state or params 
+     *    have not changed, aka a reload of the same state. It differs from reloadOnSearch because you'd
+     *    use this when you want to force a reload when *everything* is the same, including search params.
+     *
+     * @returns {promise} A promise representing the state of the new transition.
+     *
+     * Possible success values:
+     *
+     * - $state.current
+     *
+     * 
Possible rejection values:
+     *
+     * - 'transition superseded' - when a newer transition has been started after this one
+     * - 'transition prevented' - when `event.preventDefault()` has been called in a `$stateChangeStart` listener
+     * - 'transition aborted' - when `event.preventDefault()` has been called in a `$stateNotFound` listener or
+     *   when a `$stateNotFound` `event.retry` promise errors.
+     * - 'transition failed' - when a state has been unsuccessfully found after 2 tries.
+     * - *resolve error* - when an error has occurred with a `resolve`

+ * @requires ui.router.state.$state
+ * @requires $timeout
+ *
+ * @restrict A
+ *
+ * @description
+ * A directive that binds a link (`` tag) to a state. If the state has an associated 
+ * URL, the directive will automatically generate & update the `href` attribute via 
+ * the {@link ui.router.state.$state#methods_href $state.href()} method. Clicking 
+ * the link will trigger a state transition with optional parameters. 
+ *
+ * Also middle-clicking, right-clicking, and ctrl-clicking on the link will be 
+ * handled natively by the browser.
+ *
+ * You can also use relative state paths within ui-sref, just like the relative 
+ * paths passed to `$state.go()`. You just need to be aware that the path is relative
+ * to the state that the link lives in, in other words the state that loaded the 
+ * template containing the link.
+ *
+ * You can specify options to pass to {@link ui.router.state.$state#go $state.go()}
+ * using the `ui-sref-opts` attribute. Options are restricted to `location`, `inherit`,
+ * and `reload`.
+ *
+ * @example
+ * Here's an example of how you'd use ui-sref and how it would compile. If you have the 
+ * following template:
+ * 
+ * Home | About | Next page
+ * 
+ * 
+ * 

+ * 
+ * Then the compiled html would be (assuming Html5Mode is off and current state is contacts):
+ * 
+ * Home | About | Next page
+ * 
+ *

+ * @description
+ * A directive working alongside ui-sref to add classes to an element when the

+ *
+ * ui-sref-active can live on the same element as ui-sref or on a parent element. The first
+ * ui-sref-active found at the same level or above the ui-sref will be used.
+ *
+ * Will activate when the ui-sref's target state or any child state is active. If you
+ * need to activate only when the ui-sref target state is active and *not* any of
+ * it's children, then you will use

+ *
+ * The class name is interpolated **once** during the directives link time (any further changes to the
+ * interpolated value are ignored).

+/**
+ * @ngdoc object
+ * @name ui.router.util.type:UrlMatcher
+ *
+ * @description
+ * Matches URLs against patterns and extracts named parameters from the path or the search
+ * part of the URL. A URL pattern consists of a path pattern, optionally followed by '?' and a list
+ * of search parameters. Multiple search parameter names are separated by '&'. Search parameters
+ * do not influence whether or not a URL is matched, but their values are passed through into
+ * the matched parameters returned by {@link ui.router.util.type:UrlMatcher#methods_exec exec}.
+ * 
+ * Path parameter placeholders can be specified using simple colon/catch-all syntax or curly brace
+ * syntax, which optionally allows a regular expression for the parameter to be specified:
+ *
+ * * `':'` name - colon placeholder
+ * * `'*'` name - catch-all placeholder
+ * * `'{' name '}'` - curly placeholder
+ * * `'{' name ':' regexp|type '}'` - curly placeholder with regexp or type name. Should the
+ *   regexp itself contain curly braces, they must be in matched pairs or escaped with a backslash.
+ *
+ * Parameter names may contain only word characters (latin letters, digits, and underscore) and
+ * must be unique within the pattern (across both path and search parameters). For colon 
+ * placeholders or curly placeholders without an explicit regexp, a path parameter matches any
+ * number of characters other than '/'. For catch-all placeholders the path parameter matches
+ * any number of characters.
+ * 
+ * Examples:
+ * 
+ * * `'/hello/'` - Matches only if the path is exactly '/hello/'. There is no special treatment for
+ *   trailing slashes, and patterns have to match the entire path, not just a prefix.
+ * * `'/user/:id'` - Matches '/user/bob' or '/user/1234!!!' or even '/user/' but not '/user' or
+ *   '/user/bob/details'. The second path segment will be captured as the parameter 'id'.
+ * * `'/user/{id}'` - Same as the previous example, but using curly brace syntax.
+ * * `'/user/{id:[^/]*}'` - Same as the previous example.
+ * * `'/user/{id:[0-9a-fA-F]{1,8}}'` - Similar to the previous example, but only matches if the id
+ *   parameter consists of 1 to 8 hex digits.
+ * * `'/files/{path:.*}'` - Matches any URL starting with '/files/' and captures the rest of the
+ *   path into the parameter 'path'.
+ * * `'/files/*path'` - ditto.
+ * * `'/calendar/{start:date}'` - Matches "/calendar/2014-11-12" (because the pattern defined
+ *   in the built-in  `date` Type matches `2014-11-12`) and provides a Date object in $stateParams.start
+ *
+ * @param {string} pattern  The pattern to compile into a matcher.
+ * @param {Object} config  A configuration object hash:
+ * @param {Object=} parentMatcher Used to concatenate the pattern/config onto
+ *   an existing UrlMatcher
+ *
+ * * `caseInsensitive` - `true` if URL matching should be case insensitive, otherwise `false`, the default value (for backward compatibility) is `false`.
+ * * `strict` - `false` if matching against a URL with a trailing slash should be treated as equivalent to a URL without a trailing slash, the default value is `true`.
+ *
+ * @property {string} prefix  A static prefix of this pattern. The matcher guarantees that any
+ *   URL matching this matcher (i.e. any string for which {@link ui.router.util.type:UrlMatcher#methods_exec exec()} returns
+ *   non-null) will start with this prefix.
+ *
+ * @property {string} source  The pattern that was passed into the constructor
+ *
+ * @property {string} sourcePath  The path portion of the source property
+ *
+ * @property {string} sourceSearch  The search portion of the source property
+ *
+ * @property {string} regex  The constructed regex that will be used to match against the url when 
+ *   it is time to determine which url will match.
+ *
+ * @returns {Object}  New `UrlMatcher` object

+   *
+   * @param {string} name  The type name.

+   *        {@link ui.router.util.type:Type `Type`} for information on the values accepted.
+   * @param {Object|Function} definitionFn (optional) A function that is injected before the app

+   *        See {@link ui.router.util.type:Type `Type`} for information on the values accepted.
+   *
+   * @returns {Object}  Returns `$urlMatcherFactoryProvider`.
+   *
+   * @example
+   * This is a simple example of a custom type that encodes and decodes items from an
+   * array, using the array index as the URL-encoded value:
+   *
+   * 
+   * var list = ['John', 'Paul', 'George', 'Ringo'];
+   *
+   * $urlMatcherFactoryProvider.type('listItem', {

+   *     return list.indexOf(item);
+   *   },
+   *   decode: function(item) {
+   *     // Look up the list item by index
+   *     return list[parseInt(item, 10)];
+   *   },
+   *   is: function(item) {
+   *     // Ensure the item is valid by checking to see that it appears
+   *     // in the list
+   *     return list.indexOf(item) > -1;
+   *   }
+   * });
+   *
+   * $stateProvider.state('list', {
+   *   url: "/list/{item:listItem}",
+   *   controller: function($scope, $stateParams) {
+   *     console.log($stateParams.item);
+   *   }
+   * });
+   *
+   * // ...
+   *
+   * // Changes URL to '/list/3', logs "Ringo" to the console
+   * $state.go('list', { item: "Ringo" });
+   * 

+   *
+   * This is a more complex example of a type that relies on dependency injection to
+   * interact with services, and uses the parameter name from the URL to infer how to
+   * handle encoding and decoding parameter values:
+   *
+   * 
+   * // Defines a custom type that gets a value from a service,
+   * // where each service gets different types of values from
+   * // a backend API:
+   * $urlMatcherFactoryProvider.type('dbObject', {}, function(Users, Posts) {
+   *
+   *   // Matches up services to URL parameter names
+   *   var services = {
+   *     user: Users,
+   *     post: Posts
+   *   };
+   *
+   *   return {
+   *     encode: function(object) {
+   *       // Represent the object in the URL using its unique ID
+   *       return object.id;
+   *     },
+   *     decode: function(value, key) {
+   *       // Look up the object by ID, using the parameter
+   *       // name (key) to call the correct service
+   *       return services[key].findById(value);
+   *     },
+   *     is: function(object, key) {
+   *       // Check that object is a valid dbObject
+   *       return angular.isObject(object) && object.id && services[key];
+   *     }
+   *     equals: function(a, b) {
+   *       // Check the equality of decoded objects by comparing
+   *       // their unique IDs
+   *       return a.id === b.id;
+   *     }
+   *   };
+   * });
+   *
+   * // In a config() block, you can then attach URLs with
+   * // type-annotated parameters:
+   * $stateProvider.state('users', {

+ *
+ * @description
+ * The ui-view directive tells $state where to place your templates.
+ *
+ * @param {string=} name A view name. The name should be unique amongst the other views in the
+ * same state. You can have views of the same name that live in different states.
+ *
+ * @param {string=} autoscroll It allows you to set the scroll behavior of the browser window
+ * when a view is populated. By default, $anchorScroll is overridden by ui-router's custom scroll
+ * service, {@link ui.router.state.$uiViewScroll}. This custom service let's you
+ * scroll ui-view elements into view when they are populated during a state activation.
+ *
+ * *Note: To revert back to old [`$anchorScroll`](http://docs.angularjs.org/api/ng.$anchorScroll)
+ * functionality, call `$uiViewScrollProvider.useAnchorScroll()`.*
+ *
+ * @param {string=} onload Expression to evaluate whenever the view updates.
+ * 
+ * @example
+ * A view can be unnamed or named. 
+ * 
+ * 
+ * 
 
+ * 
+ * 
+ * 

+ * 

+ *
+ * You can only have one unnamed view within any template (or root html). If you are only using a 
+ * single view and it is unnamed then you can populate it like so:
+ * 
+ * 
 
+ * $stateProvider.state("home", {
+ *   template: "
HELLO!
"
+ * })
+ * 

+ * 
+ * The above is a convenient shortcut equivalent to specifying your view explicitly with the {@link ui.router.state.$stateProvider#views `views`}
+ * config property, by name, in this case an empty name:
+ * 
+ * $stateProvider.state("home", {
+ *   views: {
+ *     "": {
+ *       template: "
HELLO!
"
+ *     }
+ *   }    
+ * })
+ * 

+ * 
+ * But typically you'll only use the views property if you name your view or have more than one view 
+ * in the same template. There's not really a compelling reason to name a view if its the only one, 
+ * but you could if you wanted, like so:
+ * 
+ * 

+ * 
 
+ * 
+ * $stateProvider.state("home", {
+ *   views: {
+ *     "main": {
+ *       template: "
HELLO!
"
+ *     }
+ *   }    
+ * })
+ * 

+ * 
+ * Really though, you'll use views to set up multiple views:
+ * 
+ * 

+ * 
 
+ * 
 
+ * 

+ * 
+ * 
+ * $stateProvider.state("home", {
+ *   views: {
+ *     "": {
+ *       template: "
HELLO!
"
+ *     },
+ *     "chart": {
+ *       template: ""
+ *     },
+ *     "data": {
+ *       template: ""
+ *     }
+ *   }    
+ * })
+ *

+ * 
+ * 
+ *

+ * Angular. It can be called as follows:
+ *
+ * var exampleMinErr = minErr('example');
+ * throw exampleMinErr('one', 'This {0} is {1}', foo, bar);
+ *
+ * The above creates an instance of minErr in the example namespace. The
+ * resulting error will have a namespaced error code of example.one.  The
+ * resulting error will replace {0} with the value of foo, and {1} with the
+ * value of bar. The object is not restricted in the number of arguments it can
+ * take.
+ *
+ * If fewer arguments are specified than necessary for interpolation, the extra
+ * interpolation markers will be preserved in the final string.
+ *
+ * Since data will be parsed statically during a build step, some restrictions
+ * are applied with respect to how minErr instances are created and called.
+ * Instances should have names of the form namespaceMinErr for a minErr created
+ * using minErr('namespace') . Error codes, namespaces and template strings
+ * should all be static strings, not variables or general expressions.
+ *
+ * @param {string} module The namespace to use for the new minErr instance.
+ * @param {function} ErrorConstructor Custom error constructor to be instantiated when returning

+ *   tracking down the root of these bugs.
+ *
+ * @description
+ *
+ * Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive
+ * designates the **root element** of the application and is typically placed near the root element
+ * of the page - e.g. on the `` or `` tags.
+ *
+ * There are a few things to keep in mind when using `ngApp`:
+ * - only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`
+ *   found in the document will be used to define the root element to auto-bootstrap as an
+ *   application. To run multiple applications in an HTML document you must manually bootstrap them using
+ *   {@link angular.bootstrap} instead.
+ * - AngularJS applications cannot be nested within each other.
+ * - Do not use a directive that uses {@link ng.$compile#transclusion transclusion} on the same element as `ngApp`.
+ *   This includes directives such as {@link ng.ngIf `ngIf`}, {@link ng.ngInclude `ngInclude`} and
+ *   {@link ngRoute.ngView `ngView`}.
+ *   Doing this misplaces the app {@link ng.$rootElement `$rootElement`} and the app's {@link auto.$injector injector},
+ *   causing animations to stop working and making the injector inaccessible from outside the app.
+ *
+ * You can specify an **AngularJS module** to be used as the root module for the application.  This
+ * module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It
+ * should contain the application code needed or have dependencies on other modules that will
+ * contain the code. See {@link angular.module} for more information.
+ *
+ * In the example below if the `ngApp` directive were not placed on the `html` element then the
+ * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
+ * would not be resolved to `3`.
+ *
+ * `ngApp` is the easiest, and most common way to bootstrap an application.
+ *
+ 
+   
+   

+     I can add: {{a}} + {{b}} =  {{ a+b }}
+   

+   
+   
+   angular.module('ngAppDemo', []).controller('ngAppDemoController', function($scope) {
+     $scope.a = 1;
+     $scope.b = 2;
+   });
+   
+ 
+ *
+ * Using `ngStrictDi`, you would see something like this:
+ *
+ 
+   
+   

+       

+           I can add: {{a}} + {{b}} =  {{ a+b }}
+
+           
This renders because the controller does not fail to
+              instantiate, by using explicit annotation style (see
+              script.js for details)
+           

+       

+
+       

+           Name: 

+           Hello, {{name}}!
+
+           
This renders because the controller does not fail to

+
+       

+           I can add: {{a}} + {{b}} =  {{ a+b }}
+
+

+              on automatic function annotations (which are disabled in

+     * modules.
+     * All modules (angular core or 3rd party) that should be available to an application must be
+     * registered using this mechanism.

+     * # Module
+     *
+     * A module is a collection of services, directives, controllers, filters, and configuration information.
+     * `angular.module` is used to configure the {@link auto.$injector $injector}.
+     *
+     * ```js
+     * // Create a new module
+     * var myModule = angular.module('myModule', []);
+     *
+     * // register a new service
+     * myModule.value('appName', 'MyCoolApp');

+     *   // Configure existing providers
+     *   $locationProvider.hashPrefix('!');
+     * }]);
+     * ```
+     *
+     * Then you can create an injector and load your modules like this:
+     *
+     * ```js
+     * var injector = angular.injector(['ng', 'myModule'])
+     * ```
+     *
+     * However it's more likely that you'll just use

+ * @ngdoc function
+ * @name angular.element
+ * @module ng
+ * @kind function
+ *
+ * @description
+ * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
+ *
+ * If jQuery is available, `angular.element` is an alias for the
+ * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`
+ * delegates to Angular's built-in subset of jQuery, called "jQuery lite" or **jqLite**.
+ *
+ * jqLite is a tiny, API-compatible subset of jQuery that allows
+ * Angular to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most
+ * commonly needed functionality with the goal of having a very small footprint.
+ *
+ * To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the
+ * {@link ngJq `ngJq`} directive to specify that jqlite should be used over jQuery, or to use a
+ * specific version of jQuery if multiple versions exist on the page.
+ *
+ * 
**Note:** All element references in Angular are always wrapped with jQuery or
+ * jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.

+ *
+ * 
**Note:** Keep in mind that this function will not find elements
+ * by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)`
+ * or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.

+ *
+ * ## Angular's jqLite
+ * jqLite provides only the following jQuery methods:
+ *
+ * - [`addClass()`](http://api.jquery.com/addClass/)
+ * - [`after()`](http://api.jquery.com/after/)
+ * - [`append()`](http://api.jquery.com/append/)
+ * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters
+ * - [`bind()`](http://api.jquery.com/bind/) - Does not support namespaces, selectors or eventData
+ * - [`children()`](http://api.jquery.com/children/) - Does not support selectors
+ * - [`clone()`](http://api.jquery.com/clone/)
+ * - [`contents()`](http://api.jquery.com/contents/)
+ * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`.
+ *   As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing.
+ * - [`data()`](http://api.jquery.com/data/)
+ * - [`detach()`](http://api.jquery.com/detach/)
+ * - [`empty()`](http://api.jquery.com/empty/)
+ * - [`eq()`](http://api.jquery.com/eq/)
+ * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
+ * - [`hasClass()`](http://api.jquery.com/hasClass/)
+ * - [`html()`](http://api.jquery.com/html/)
+ * - [`next()`](http://api.jquery.com/next/) - Does not support selectors
+ * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
+ * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter
+ * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors
+ * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors
+ * - [`prepend()`](http://api.jquery.com/prepend/)
+ * - [`prop()`](http://api.jquery.com/prop/)
+ * - [`ready()`](http://api.jquery.com/ready/)
+ * - [`remove()`](http://api.jquery.com/remove/)
+ * - [`removeAttr()`](http://api.jquery.com/removeAttr/)
+ * - [`removeClass()`](http://api.jquery.com/removeClass/)
+ * - [`removeData()`](http://api.jquery.com/removeData/)
+ * - [`replaceWith()`](http://api.jquery.com/replaceWith/)
+ * - [`text()`](http://api.jquery.com/text/)
+ * - [`toggleClass()`](http://api.jquery.com/toggleClass/)
+ * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers.
+ * - [`unbind()`](http://api.jquery.com/unbind/) - Does not support namespaces or event object as parameter
+ * - [`val()`](http://api.jquery.com/val/)
+ * - [`wrap()`](http://api.jquery.com/wrap/)
+ *
+ * ## jQuery/jqLite Extras
+ * Angular also provides the following additional methods and events to both jQuery and jqLite:
+ *
+ * ### Events
+ * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
+ *    on all DOM nodes being removed.  This can be used to clean up any 3rd party bindings to the DOM
+ *    element before it is removed.
+ *
+ * ### Methods
+ * - `controller(name)` - retrieves the controller of the current element or its parent. By default
+ *   retrieves controller associated with the `ngController` directive. If `name` is provided as
+ *   camelCase directive name, then the controller for this directive will be retrieved (e.g.
+ *   `'ngModel'`).
+ * - `injector()` - retrieves the injector of the current element or its parent.
+ * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current
+ *   element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to
+ *   be enabled.
+ * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the
+ *   current element. This getter should be used only on elements that contain a directive which starts a new isolate
+ *   scope. Calling `scope()` on this element always returns the original non-isolate scope.
+ *   Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled.
+ * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
+ *   parent element is reached.
+ *
+ * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
+ * @returns {Object} jQuery object.

+ * # Injection Function Annotation
+ *
+ * JavaScript does not have annotations, and annotations are needed for dependency injection. The
+ * following are all valid ways of annotating function with injection arguments and are equivalent.
+ *
+ * ```js
+ *   // inferred (only works if code not minified/obfuscated)
+ *   $injector.invoke(function(serviceA){});
+ *
+ *   // annotated

+ * ```
+ *
+ * ## Inference
+ *
+ * In JavaScript calling `toString()` on a function returns the function definition. The definition
+ * can then be parsed and the function arguments can be extracted. This method of discovering
+ * annotations is disallowed when the injector is in strict mode.
+ * *NOTE:* This does not work with minification, and obfuscation tools since these tools change the

+ *
+ * @description
+ * Returns an array of service names which the function is requesting for injection. This API is
+ * used by the injector to determine which services need to be injected into the function when the
+ * function is invoked. There are three ways in which the function can be annotated with the needed
+ * dependencies.
+ *
+ * # Argument names
+ *
+ * The simplest form is to extract the dependencies from the arguments of the function. This is done
+ * by converting the function into a string using `toString()` method and extracting the argument
+ * names.
+ * ```js
+ *   // Given
+ *   function MyController($scope, $route) {
+ *     // ...
+ *   }
+ *
+ *   // Then
+ *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
+ * ```
+ *
+ * You can disallow this method by using strict injection mode.
+ *
+ * This method does not work with code minification / obfuscation. For this reason the following
+ * annotation strategies are supported.
+ *
+ * # The `$inject` property
+ *
+ * If a function has an `$inject` property and its value is an array of strings, then the strings
+ * represent names of services to be injected into the function.
+ * ```js
+ *   // Given
+ *   var MyController = function(obfuscatedScope, obfuscatedRoute) {
+ *     // ...
+ *   }
+ *   // Define function dependencies
+ *   MyController['$inject'] = ['$scope', '$route'];
+ *
+ *   // Then
+ *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
+ * ```
+ *
+ * # The array notation
+ *
+ * It is often desirable to inline Injected functions and that's when setting the `$inject` property
+ * is very inconvenient. In these situations using the array notation to specify the dependencies in
+ * a way that survives minification is a better choice:
+ *
+ * ```js
+ *   // We wish to write this (not minification / obfuscation safe)
+ *   injector.invoke(function($compile, $rootScope) {
+ *     // ...
+ *   });
+ *
+ *   // We are forced to write break inlining
+ *   var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
+ *     // ...
+ *   };
+ *   tmpFn.$inject = ['$compile', '$rootScope'];
+ *   injector.invoke(tmpFn);
+ *
+ *   // To better support inline function the inline annotation is supported
+ *   injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
+ *     // ...
+ *   }]);
+ *
+ *   // Therefore
+ *   expect(injector.annotate(
+ *      ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])

+ * {@link angular.Module}.
+ *
+ * An Angular **service** is a singleton object created by a **service factory**.  These **service
+ * factories** are functions which, in turn, are created by a **service provider**.
+ * The **service providers** are constructor functions. When instantiated they must contain a

+ *
+ * When you request a service, the {@link auto.$injector $injector} is responsible for finding the
+ * correct **service provider**, instantiating it and then calling its `$get` **service factory**
+ * function to get the instance of the **service**.
+ *
+ * Often services have no configuration options and there is no need to add methods to the service
+ * provider.  The provider will be no more than a constructor function with a `$get` property. For
+ * these cases the {@link auto.$provide $provide} service has additional helper methods to register
+ * services without specifying a provider.
+ *
+ * * {@link auto.$provide#provider provider(provider)} - registers a **service provider** with the

+ * * {@link auto.$provide#service service(class)} - registers a **constructor function**, `class`
+ *     that will be wrapped in a **service provider** object, whose `$get` property will instantiate
+ *      a new object using the given constructor function.

+/**
+ * @ngdoc method

+ * @description
+ *
+ * Register a **provider function** with the {@link auto.$injector $injector}. Provider functions
+ * are constructor functions, whose instances are responsible for "providing" a factory for a
+ * service.
+ *
+ * Service provider names start with the name of the service they provide followed by `Provider`.
+ * For example, the {@link ng.$log $log} service has a provider called
+ * {@link ng.$logProvider $logProvider}.
+ *
+ * Service provider objects can have additional methods which allow configuration of the provider
+ * and its service. Importantly, you can configure what kind of service is created by the `$get`
+ * method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a
+ * method {@link ng.$logProvider#debugEnabled debugEnabled}
+ * which lets you specify whether the {@link ng.$log $log} service will log debug messages to the
+ * console or not.
+ *
+ * @param {string} name The name of the instance. NOTE: the provider will be available under `name +
+                        'Provider'` key.
+ * @param {(Object|function())} provider If the provider is:
+ *
+ *   - `Object`: then it should have a `$get` method. The `$get` method will be invoked using
+ *     {@link auto.$injector#invoke $injector.invoke()} when an instance needs to be created.
+ *   - `Constructor`: a new instance of the provider will be created using
+ *     {@link auto.$injector#instantiate $injector.instantiate()}, then treated as `object`.
+ *
+ * @returns {Object} registered provider instance
+
+ * @example
+ *
+ * The following example shows how to create a simple event tracking service and register it using
+ * {@link auto.$provide#provider $provide.provider()}.
+ *
+ * ```js
+ *  // Define the eventTracker provider
+ *  function EventTrackerProvider() {
+ *    var trackingUrl = '/track';

+   *
+   * Additionally, you can use its {@link ng.$anchorScroll#yOffset yOffset} property to specify a

+   *
+   * @param {string=} hash The hash specifying the element to scroll to. If omitted, the value of

+   *
+   * @property {(number|function|jqLite)} yOffset
+   * If set, specifies a vertical scroll-offset. This is often useful when there are fixed
+   * positioned elements at the top of the page, such as navbars, headers etc.
+   *
+   * `yOffset` can be specified in various ways:
+   * - **number**: A fixed number of pixels to be used as offset.


+   * - **function**: A getter function called everytime `$anchorScroll()` is executed. Must return
+   *   a number representing the offset (in pixels).


+   * - **jqLite**: A jqLite/jQuery element to be used for specifying the offset. The distance from
+   *   the top of the page to the element's bottom will be used as offset.

+   *   **Note**: The element will be taken into account only as long as its `position` is set to
+   *   `fixed`. This option is useful, when dealing with responsive navbars/headers that adjust
+   *   their height and/or positioning according to the viewport's size.
+   *
+   * 

+   * 

+   * In order for `yOffset` to work properly, scrolling should take place on the document's root and
+   * not some child element.
+   * 

+   *
+   * @example
+     
+       
+         

+           Go to bottom
+            You're at the bottom!

+ * @kind function
+ *
+ * @description
+ * Compiles an HTML string or DOM into a template and produces a template function, which
+ * can then be used to link {@link ng.$rootScope.Scope `scope`} and the template together.
+ *
+ * The compilation is a process of walking the DOM tree and matching DOM elements to
+ * {@link ng.$compileProvider#directive directives}.
+ *
+ * 

+ * **Note:** This document is an in-depth reference of all directive options.
+ * For a gentle introduction to directives with examples of common use cases,
+ * see the {@link guide/directive directive guide}.
+ * 

+ *
+ * ## Comprehensive Directive API
+ *
+ * There are many different options for a directive.
+ *
+ * The difference resides in the return value of the factory function.
+ * You can either return a "Directive Definition Object" (see below) that defines the directive properties,
+ * or just the `postLink` function (all other properties will have the default values).
+ *
+ * 

+ * **Best Practice:** It's recommended to use the "directive definition object" form.
+ * 

+ *
+ * Here's an example directive declared with a Directive Definition Object:
+ *
+ * ```js
+ *   var myModule = angular.module(...);
+ *
+ *   myModule.directive('directiveName', function factory(injectables) {
+ *     var directiveDefinitionObject = {
+ *       priority: 0,
+ *       template: '
', // or // function(tElement, tAttrs) { ... },
+ *       // or
+ *       // templateUrl: 'directive.html', // or // function(tElement, tAttrs) { ... },
+ *       transclude: false,
+ *       restrict: 'A',
+ *       templateNamespace: 'html',
+ *       scope: false,
+ *       controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
+ *       controllerAs: 'stringIdentifier',
+ *       bindToController: false,
+ *       require: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],
+ *       compile: function compile(tElement, tAttrs, transclude) {
+ *         return {
+ *           pre: function preLink(scope, iElement, iAttrs, controller) { ... },
+ *           post: function postLink(scope, iElement, iAttrs, controller) { ... }
+ *         }
+ *         // or
+ *         // return function postLink( ... ) { ... }
+ *       },
+ *       // or
+ *       // link: {
+ *       //  pre: function preLink(scope, iElement, iAttrs, controller) { ... },
+ *       //  post: function postLink(scope, iElement, iAttrs, controller) { ... }
+ *       // }
+ *       // or
+ *       // link: function postLink( ... ) { ... }
+ *     };
+ *     return directiveDefinitionObject;
+ *   });
+ * ```
+ *
+ * 

+ * **Note:** Any unspecified options will use the default value. You can see the default values below.
+ * 

+ *
+ * Therefore the above can be simplified as:
+ *
+ * ```js
+ *   var myModule = angular.module(...);
+ *
+ *   myModule.directive('directiveName', function factory(injectables) {
+ *     var directiveDefinitionObject = {
+ *       link: function postLink(scope, iElement, iAttrs) { ... }
+ *     };
+ *     return directiveDefinitionObject;
+ *     // or
+ *     // return function postLink(scope, iElement, iAttrs) { ... }
+ *   });
+ * ```
+ *
+ *
+ *
+ * ### Directive Definition Object
+ *
+ * The directive definition object provides instructions to the {@link ng.$compile
+ * compiler}. The attributes are:
+ *
+ * #### `multiElement`
+ * When this property is set to true, the HTML compiler will collect DOM nodes between
+ * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them
+ * together as the directive elements. It is recommended that this feature be used on directives
+ * which are not strictly behavioral (such as {@link ngClick}), and which
+ * do not manipulate or replace child nodes (such as {@link ngInclude}).
+ *
+ * #### `priority`
+ * When there are multiple directives defined on a single DOM element, sometimes it
+ * is necessary to specify the order in which the directives are applied. The `priority` is used
+ * to sort the directives before their `compile` functions get called. Priority is defined as a
+ * number. Directives with greater numerical `priority` are compiled first. Pre-link functions
+ * are also run in priority order, but post-link functions are run in reverse order. The order
+ * of directives with the same priority is undefined. The default priority is `0`.
+ *
+ * #### `terminal`
+ * If set to true then the current `priority` will be the last set of directives
+ * which will execute (any directives at the current priority will still execute
+ * as the order of execution on same `priority` is undefined). Note that expressions
+ * and other directives used in the directive's template will also be excluded from execution.
+ *
+ * #### `scope`
+ * The scope property can be `true`, an object or a falsy value:
+ *
+ * * **falsy:** No scope will be created for the directive. The directive will use its parent's scope.
+ *
+ * * **`true`:** A new child scope that prototypically inherits from its parent will be created for
+ * the directive's element. If multiple directives on the same element request a new scope,
+ * only one new scope is created. The new scope rule does not apply for the root of the template
+ * since the root of the template always gets a new scope.
+ *
+ * * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's element. The
+ * 'isolate' scope differs from normal scope in that it does not prototypically inherit from its parent
+ * scope. This is useful when creating reusable components, which should not accidentally read or modify
+ * data in the parent scope.
+ *
+ * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the
+ * directive's element. These local properties are useful for aliasing values for templates. The keys in
+ * the object hash map to the name of the property on the isolate scope; the values define how the property
+ * is bound to the parent scope, via matching attributes on the directive's element:
+ *
+ * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
+ *   always a string since DOM attributes are strings. If no `attr` name is specified then the
+ *   attribute name is assumed to be the same as the local name. Given `` and the isolate scope definition `scope: { localName:'@myAttr' }`,
+ *   the directive's scope property `localName` will reflect the interpolated value of `hello
+ *   {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's
+ *   scope. The `name` is read from the parent scope (not the directive's scope).
+ *
+ * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression
+ *   passed via the attribute `attr`. The expression is evaluated in the context of the parent scope.
+ *   If no `attr` name is specified then the attribute name is assumed to be the same as the local
+ *   name. Given `` and the isolate scope definition `scope: {
+ *   localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the
+ *   value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in
+ *   `localModel` and vice versa. Optional attributes should be marked as such with a question mark:
+ *   `=?` or `=?attr`. If the binding expression is non-assignable, or if the attribute isn't
+ *   optional and doesn't exist, an exception ({@link error/$compile/nonassign `$compile:nonassign`})
+ *   will be thrown upon discovering changes to the local value, since it will be impossible to sync
+ *   them back to the parent scope. By default, the {@link ng.$rootScope.Scope#$watch `$watch`}
+ *   method is used for tracking changes, and the equality check is based on object identity.
+ *   However, if an object literal or an array literal is passed as the binding expression, the
+ *   equality check is done by value (using the {@link angular.equals} function). It's also possible
+ *   to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection
+ *   `$watchCollection`}: use `=*` or `=*attr` (`=*?` or `=*?attr` if the attribute is optional).
+ *
+  * * `<` or `` and directive definition of
+ *   `scope: { localModel:'` and the isolate scope definition `scope: {
+ *   localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for
+ *   the `count = count + value` expression. Often it's desirable to pass data from the isolated scope
+ *   via an expression to the parent scope. This can be done by passing a map of local variable names
+ *   and values into the expression wrapper fn. For example, if the expression is `increment(amount)`
+ *   then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`.
+ *
+ * In general it's possible to apply more than one directive to one element, but there might be limitations
+ * depending on the type of scope required by the directives. The following points will help explain these limitations.
+ * For simplicity only two directives are taken into account, but it is also applicable for several directives:
+ *
+ * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope
+ * * **child scope** + **no scope** =>  Both directives will share one single child scope
+ * * **child scope** + **child scope** =>  Both directives will share one single child scope
+ * * **isolated scope** + **no scope** =>  The isolated directive will use it's own created isolated scope. The other directive will use
+ * its parent's scope
+ * * **isolated scope** + **child scope** =>  **Won't work!** Only one scope can be related to one element. Therefore these directives cannot
+ * be applied to the same element.
+ * * **isolated scope** + **isolated scope**  =>  **Won't work!** Only one scope can be related to one element. Therefore these directives
+ * cannot be applied to the same element.
+ *
+ *
+ * #### `bindToController`
+ * This property is used to bind scope properties directly to the controller. It can be either
+ * `true` or an object hash with the same format as the `scope` property. Additionally, a controller
+ * alias must be set, either by using `controllerAs: 'myAlias'` or by specifying the alias in the controller
+ * definition: `controller: 'myCtrl as myAlias'`.
+ *
+ * When an isolate scope is used for a directive (see above), `bindToController: true` will
+ * allow a component to have its properties bound to the controller, rather than to scope.
+ *
+ * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller
+ * properties. You can access these bindings once they have been initialized by providing a controller method called
+ * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings
+ * initialized.
+ *
+ * 

+ * **Deprecation warning:** although bindings for non-ES6 class controllers are currently
+ * bound to `this` before the controller constructor is called, this use is now deprecated. Please place initialization
+ * code that relies upon bindings inside a `$onInit` method on the controller, instead.
+ * 

+ *
+ * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property.
+ * This will set up the scope bindings to the controller directly. Note that `scope` can still be used
+ * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate
+ * scope (useful for component directives).
+ *
+ * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`.
+ *
+ *
+ * #### `controller`
+ * Controller constructor function. The controller is instantiated before the
+ * pre-linking phase and can be accessed by other directives (see
+ * `require` attribute). This allows the directives to communicate with each other and augment
+ * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
+ *
+ * * `$scope` - Current scope associated with the element
+ * * `$element` - Current element
+ * * `$attrs` - Current attributes object for the element
+ * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:
+ *   `function([scope], cloneLinkingFn, futureParentElement, slotName)`:
+ *    * `scope`: (optional) override the scope.
+ *    * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content.
+ *    * `futureParentElement` (optional):
+ *        * defines the parent to which the `cloneLinkingFn` will add the cloned elements.
+ *        * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.
+ *        * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)
+ *          and when the `cloneLinkinFn` is passed,
+ *          as those elements need to created and cloned in a special way when they are defined outside their
+ *          usual containers (e.g. like ``).
+ *        * See also the `directive.templateNamespace` property.
+ *    * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`)
+ *      then the default translusion is provided.
+ *    The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns
+ *    `true` if the specified slot contains content (i.e. one or more DOM nodes).
+ *
+ * The controller can provide the following methods that act as life-cycle hooks:
+ * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and
+ *   had their bindings initialized (and before the pre & post linking functions for the directives on
+ *   this element). This is a good place to put initialization code for your controller.
+ * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The
+ *   `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an
+ *   object of the form `{ currentValue: ..., previousValue: ... }`. Use this hook to trigger updates within a component
+ *   such as cloning the bound value to prevent accidental mutation of the outer value.
+ * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing
+ *   external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in
+ *   the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent
+ *   components will have their `$onDestroy()` hook called before child components.
+ * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link
+ *   function this hook can be used to set up DOM event handlers and do direct DOM manipulation.
+ *   Note that child elements that contain `templateUrl` directives will not have been compiled and linked since
+ *   they are waiting for their template to load asynchronously and their own compilation and linking has been
+ *   suspended until that occurs.
+ *
+ *
+ * #### `require`
+ * Require another directive and inject its controller as the fourth argument to the linking function. The
+ * `require` property can be a string, an array or an object:
+ * * a **string** containing the name of the directive to pass to the linking function
+ * * an **array** containing the names of directives to pass to the linking function. The argument passed to the
+ * linking function will be an array of controllers in the same order as the names in the `require` property
+ * * an **object** whose property values are the names of the directives to pass to the linking function. The argument
+ * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding
+ * controllers.
+ *
+ * If the `require` property is an object and `bindToController` is truthy, then the required controllers are
+ * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers
+ * have been constructed but before `$onInit` is called.
+ * See the {@link $compileProvider#component} helper for an example of how this can be used.
+ *
+ * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is
+ * raised (unless no link function is specified and the required controllers are not being bound to the directive
+ * controller, in which case error checking is skipped). The name can be prefixed with:
+ *
+ * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
+ * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
+ * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.
+ * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.
+ * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass
+ *   `null` to the `link` fn if not found.
+ * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass
+ *   `null` to the `link` fn if not found.
+ *
+ *
+ * #### `controllerAs`
+ * Identifier name for a reference to the controller in the directive's scope.
+ * This allows the controller to be referenced from the directive template. This is especially
+ * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible
+ * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the
+ * `controllerAs` reference might overwrite a property that already exists on the parent scope.
+ *
+ *
+ * #### `restrict`
+ * String of subset of `EACM` which restricts the directive to a specific directive
+ * declaration style. If omitted, the defaults (elements and attributes) are used.
+ *
+ * * `E` - Element name (default): ``
+ * * `A` - Attribute (default): `
`
+ * * `C` - Class: `
`
+ * * `M` - Comment: ``
+ *
+ *
+ * #### `templateNamespace`
+ * String representing the document type used by the markup in the template.
+ * AngularJS needs this information as those elements need to be created and cloned
+ * in a special way when they are defined outside their usual containers like `` and ``.
+ *
+ * * `html` - All root nodes in the template are HTML. Root nodes may also be
+ *   top-level elements such as `` or ``.
+ * * `svg` - The root nodes in the template are SVG elements (excluding ``).
+ * * `math` - The root nodes in the template are MathML elements (excluding ``).
+ *
+ * If no `templateNamespace` is specified, then the namespace is considered to be `html`.
+ *
+ * #### `template`
+ * HTML markup that may:
+ * * Replace the contents of the directive's element (default).
+ * * Replace the directive's element itself (if `replace` is true - DEPRECATED).
+ * * Wrap the contents of the directive's element (if `transclude` is true).
+ *
+ * Value may be:
+ *
+ * * A string. For example `
{{delete_str}}
`.
+ * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`
+ *   function api below) and returns a string value.
+ *
+ *
+ * #### `templateUrl`
+ * This is similar to `template` but the template is loaded from the specified URL, asynchronously.
+ *
+ * Because template loading is asynchronous the compiler will suspend compilation of directives on that element
+ * for later when the template has been resolved.  In the meantime it will continue to compile and link
+ * sibling and parent elements as though this element had not contained any directives.
+ *
+ * The compiler does not suspend the entire compilation to wait for templates to be loaded because this
+ * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the
+ * case when only one deeply nested directive has `templateUrl`.
+ *
+ * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}
+ *
+ * You can specify `templateUrl` as a string representing the URL or as a function which takes two
+ * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
+ * a string value representing the url.  In either case, the template URL is passed through {@link
+ * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.
+ *
+ *
+ * #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0)
+ * specify what the template should replace. Defaults to `false`.
+ *
+ * * `true` - the template will replace the directive's element.
+ * * `false` - the template will replace the contents of the directive's element.
+ *
+ * The replacement process migrates all of the attributes / classes from the old element to the new
+ * one. See the {@link guide/directive#template-expanding-directive
+ * Directives Guide} for an example.
+ *
+ * There are very few scenarios where element replacement is required for the application function,
+ * the main one being reusable custom components that are used within SVG contexts
+ * (because SVG doesn't work with custom elements in the DOM tree).
+ *
+ * #### `transclude`
+ * Extract the contents of the element where the directive appears and make it available to the directive.
+ * The contents are compiled and provided to the directive as a **transclusion function**. See the
+ * {@link $compile#transclusion Transclusion} section below.
+ *
+ *
+ * #### `compile`
+ *
+ * ```js
+ *   function compile(tElement, tAttrs, transclude) { ... }
+ * ```
+ *
+ * The compile function deals with transforming the template DOM. Since most directives do not do
+ * template transformation, it is not used often. The compile function takes the following arguments:
+ *
+ *   * `tElement` - template element - The element where the directive has been declared. It is
+ *     safe to do template transformation on the element and child elements only.
+ *
+ *   * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
+ *     between all directive compile functions.
+ *
+ *   * `transclude` -  [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`
+ *
+ * 

+ * **Note:** The template instance and the link instance may be different objects if the template has
+ * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
+ * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
+ * should be done in a linking function rather than in a compile function.
+ * 

+
+ * 

+ * **Note:** The compile function cannot handle directives that recursively use themselves in their
+ * own templates or compile functions. Compiling these directives results in an infinite loop and
+ * stack overflow errors.
+ *
+ * This can be avoided by manually using $compile in the postLink function to imperatively compile
+ * a directive's template instead of relying on automatic template compilation via `template` or
+ * `templateUrl` declaration or manual compilation inside the compile function.
+ * 

+ *
+ * 

+ * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it
+ *   e.g. does not know about the right outer scope. Please use the transclude function that is passed
+ *   to the link function instead.
+ * 

+
+ * A compile function can have a return value which can be either a function or an object.
+ *
+ * * returning a (post-link) function - is equivalent to registering the linking function via the
+ *   `link` property of the config object when the compile function is empty.
+ *
+ * * returning an object with function(s) registered via `pre` and `post` properties - allows you to
+ *   control when a linking function should be called during the linking phase. See info about
+ *   pre-linking and post-linking functions below.
+ *
+ *
+ * #### `link`
+ * This property is used only if the `compile` property is not defined.
+ *
+ * ```js
+ *   function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
+ * ```
+ *
+ * The link function is responsible for registering DOM listeners as well as updating the DOM. It is
+ * executed after the template has been cloned. This is where most of the directive logic will be
+ * put.
+ *
+ *   * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the
+ *     directive for registering {@link ng.$rootScope.Scope#$watch watches}.
+ *
+ *   * `iElement` - instance element - The element where the directive is to be used. It is safe to
+ *     manipulate the children of the element only in `postLink` function since the children have
+ *     already been linked.
+ *
+ *   * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
+ *     between all directive linking functions.
+ *
+ *   * `controller` - the directive's required controller instance(s) - Instances are shared
+ *     among all directives, which allows the directives to use the controllers as a communication
+ *     channel. The exact value depends on the directive's `require` property:
+ *       * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one
+ *       * `string`: the controller instance
+ *       * `array`: array of controller instances
+ *
+ *     If a required controller cannot be found, and it is optional, the instance is `null`,
+ *     otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.
+ *
+ *     Note that you can also require the directive's own controller - it will be made available like
+ *     any other controller.
+ *
+ *   * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
+ *     This is the same as the `$transclude`
+ *     parameter of directive controllers, see there for details.
+ *     `function([scope], cloneLinkingFn, futureParentElement)`.
+ *
+ * #### Pre-linking function
+ *
+ * Executed before the child elements are linked. Not safe to do DOM transformation since the
+ * compiler linking function will fail to locate the correct elements for linking.
+ *
+ * #### Post-linking function
+ *
+ * Executed after the child elements are linked.
+ *
+ * Note that child elements that contain `templateUrl` directives will not have been compiled
+ * and linked since they are waiting for their template to load asynchronously and their own
+ * compilation and linking has been suspended until that occurs.
+ *
+ * It is safe to do DOM transformation in the post-linking function on elements that are not waiting
+ * for their async templates to be resolved.
+ *
+ *
+ * ### Transclusion
+ *
+ * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and
+ * copying them to another part of the DOM, while maintaining their connection to the original AngularJS
+ * scope from where they were taken.
+ *
+ * Transclusion is used (often with {@link ngTransclude}) to insert the
+ * original contents of a directive's element into a specified place in the template of the directive.
+ * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded
+ * content has access to the properties on the scope from which it was taken, even if the directive
+ * has isolated scope.
+ * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.
+ *
+ * This makes it possible for the widget to have private state for its template, while the transcluded
+ * content has access to its originating scope.
+ *
+ * 

+ * **Note:** When testing an element transclude directive you must not place the directive at the root of the
+ * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives
+ * Testing Transclusion Directives}.
+ * 

+ *
+ * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the
+ * directive's element, the entire element or multiple parts of the element contents:
+ *
+ * * `true` - transclude the content (i.e. the child nodes) of the directive's element.
+ * * `'element'` - transclude the whole of the directive's element including any directives on this
+ *   element that defined at a lower priority than this directive. When used, the `template`
+ *   property is ignored.
+ * * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template.
+ *
+ * **Mult-slot transclusion** is declared by providing an object for the `transclude` property.
+ *
+ * This object is a map where the keys are the name of the slot to fill and the value is an element selector
+ * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`)
+ * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc).
+ *
+ * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives}
+ *
+ * If the element selector is prefixed with a `?` then that slot is optional.
+ *
+ * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `` elements to
+ * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive.
+ *
+ * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements
+ * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call
+ * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and
+ * injectable into the directive's controller.
+ *
+ *
+ * #### Transclusion Functions
+ *
+ * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion
+ * function** to the directive's `link` function and `controller`. This transclusion function is a special
+ * **linking function** that will return the compiled contents linked to a new transclusion scope.
+ *
+ * 

+ * If you are just using {@link ngTransclude} then you don't need to worry about this function, since
+ * ngTransclude will deal with it for us.
+ * 

+ *
+ * If you want to manually control the insertion and removal of the transcluded content in your directive
+ * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery
+ * object that contains the compiled DOM, which is linked to the correct transclusion scope.
+ *
+ * When you call a transclusion function you can pass in a **clone attach function**. This function accepts
+ * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded
+ * content and the `scope` is the newly created transclusion scope, to which the clone is bound.
+ *
+ * 

+ * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function
+ * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.
+ * 

+ *
+ * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone
+ * attach function**:
+ *
+ * ```js
+ * var transcludedContent, transclusionScope;
+ *
+ * $transclude(function(clone, scope) {
+ *   element.append(clone);
+ *   transcludedContent = clone;
+ *   transclusionScope = scope;
+ * });
+ * ```
+ *
+ * Later, if you want to remove the transcluded content from your DOM then you should also destroy the
+ * associated transclusion scope:
+ *
+ * ```js
+ * transcludedContent.remove();
+ * transclusionScope.$destroy();
+ * ```
+ *
+ * 

+ * **Best Practice**: if you intend to add and remove transcluded content manually in your directive
+ * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),
+ * then you are also responsible for calling `$destroy` on the transclusion scope.
+ * 

+ *
+ * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}
+ * automatically destroy their transcluded clones as necessary so you do not need to worry about this if
+ * you are simply using {@link ngTransclude} to inject the transclusion into your directive.
+ *
+ *
+ * #### Transclusion Scopes
+ *
+ * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion
+ * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed
+ * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it
+ * was taken.
+ *
+ * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look
+ * like this:
+ *
+ * ```html
+ * 

+ *   

+ *     

+ *     

+ *   

+ * 

+ * ```
+ *
+ * The `$parent` scope hierarchy will look like this:
+ *
+   ```
+   - $rootScope
+     - isolate
+       - transclusion
+   ```
+ *
+ * but the scopes will inherit prototypically from different scopes to their `$parent`.
+ *
+   ```
+   - $rootScope
+     - transclusion
+   - isolate
+   ```
+ *
+ *
+ * ### Attributes
+ *
+ * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
+ * `link()` or `compile()` functions. It has a variety of uses.
+ *
+ * * *Accessing normalized attribute names:* Directives like 'ngBind' can be expressed in many ways:
+ *   'ng:bind', `data-ng-bind`, or 'x-ng-bind'. The attributes object allows for normalized access
+ *   to the attributes.
+ *
+ * * *Directive inter-communication:* All directives share the same instance of the attributes
+ *   object which allows the directives to use the attributes object as inter directive
+ *   communication.
+ *
+ * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
+ *   allowing other directives to read the interpolated value.
+ *
+ * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
+ *   that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
+ *   the only way to easily get the actual value because during the linking phase the interpolation
+ *   hasn't been evaluated yet and so the value is at this time set to `undefined`.
+ *
+ * ```js
+ * function linkingFn(scope, elm, attrs, ctrl) {
+ *   // get the attribute value
+ *   console.log(attrs.ngModel);
+ *
+ *   // change the attribute
+ *   attrs.$set('ngModel', 'new value');
+ *
+ *   // observe changes to interpolated attribute
+ *   attrs.$observe('ngModel', function(value) {
+ *     console.log('ngModel has changed value to ' + value);
+ *   });
+ * }
+ * ```
+ *
+ * ## Example
+ *
+ * 

+ * **Note**: Typically directives are registered with `module.directive`. The example below is
+ * to illustrate how `$compile` works.
+ * 

+ *
+ 
+   
+    
+    

+       

+       

+      

+    

+   
+   
+     it('should auto compile', function() {
+       var textarea = $('textarea');
+       var output = $('div[compile]');
+       // The initial state reads 'Hello Angular'.
+       expect(output.getText()).toBe('Hello Angular');
+       textarea.clear();
+       textarea.sendKeys('{{name}}!');
+       expect(output.getText()).toBe('Angular!');
+     });
+   
+ 
+
+ *
+ *
+ * @param {string|DOMElement} element Element or HTML string to compile into a template function.
+ * @param {function(angular.Scope, cloneAttachFn=)} transclude function available to directives - DEPRECATED.
+ *
+ * 

+ * **Note:** Passing a `transclude` function to the $compile function is deprecated, as it
+ *   e.g. will not use the right outer scope. Please pass the transclude function as a
+ *   `parentBoundTranscludeFn` to the link function instead.
+ * 

+ *
+ * @param {number} maxPriority only apply directives lower than given priority (Only effects the
+ *                 root element(s), not their children)
+ * @returns {function(scope, cloneAttachFn=, options=)} a link function which is used to bind template
+ * (a DOM element/tree) to a scope. Where:
+ *
+ *  * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
+ *  * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
+ *  `template` and call the `cloneAttachFn` function allowing the caller to attach the
+ *  cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
+ *  called as: 
 `cloneAttachFn(clonedElement, scope)` where:
+ *
+ *      * `clonedElement` - is a clone of the original `element` passed into the compiler.
+ *      * `scope` - is the current scope with which the linking function is working with.
+ *
+ *  * `options` - An optional object hash with linking options. If `options` is provided, then the following
+ *  keys may be used to control linking behavior:
+ *
+ *      * `parentBoundTranscludeFn` - the transclude function made available to
+ *        directives; if given, it will be passed through to the link functions of
+ *        directives found in `element` during compilation.
+ *      * `transcludeControllers` - an object hash with keys that map controller names
+ *        to a hash with the key `instance`, which maps to the controller instance;
+ *        if given, it will make the controllers available to directives on the compileNode:
+ *        ```
+ *        {
+ *          parent: {
+ *            instance: parentControllerInstance
+ *          }
+ *        }
+ *        ```
+ *      * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add
+ *        the cloned elements; only needed for transcludes that are allowed to contain non html
+ *        elements (e.g. SVG elements). See also the directive.controller property.
+ *
+ * Calling the linking function returns the element of the template. It is either the original
+ * element passed in, or the clone of the element if the `cloneAttachFn` is provided.
+ *
+ * After linking the view is not updated until after a call to $digest which typically is done by
+ * Angular automatically.
+ *
+ * If you need access to the bound view, there are two ways to do it:
+ *
+ * - If you are not asking the linking function to clone the template, create the DOM element(s)
+ *   before you send them to the compiler and keep this reference around.
+ *   ```js
+ *     var element = $compile('
{{total}}
')(scope);
+ *   ```
+ *
+ * - if on the other hand, you need the element to be cloned, the view reference from the original
+ *   example would not point to the clone, but rather to the original template that was cloned. In
+ *   this case, you can access the clone via the cloneAttachFn:
+ *   ```js
+ *     var templateElement = angular.element('
{{total}}
'),
+ *         scope = ....;
+ *
+ *     var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
+ *       //attach the clone to DOM document at the right place
+ *     });
+ *
+ *     //now we have reference to the cloned DOM via `clonedElement`
+ *   ```
+ *
+ *
+ * For information on how the compiler works, see the
+ * {@link guide/compiler Angular HTML Compiler} section of the Developer Guide.

+   * @description
+   * Register a **component definition** with the compiler. This is a shorthand for registering a special
+   * type of directive, which represents a self-contained UI component in your application. Such components
+   * are always isolated (i.e. `scope: {}`) and are always restricted to elements (i.e. `restrict: 'E'`).
+   *
+   * Component definitions are very simple and do not require as much configuration as defining general
+   * directives. Component definitions usually consist only of a template and a controller backing it.
+   *
+   * In order to make the definition easier, components enforce best practices like use of `controllerAs`,
+   * `bindToController`. They always have **isolate scope** and are restricted to elements.
+   *
+   * Here are a few examples of how you would usually define components:
+   *
+   * ```js
+   *   var myMod = angular.module(...);
+   *   myMod.component('myComp', {
+   *     template: '
My name is {{$ctrl.name}}
',
+   *     controller: function() {
+   *       this.name = 'shahar';
+   *     }
+   *   });
+   *
+   *   myMod.component('myComp', {
+   *     template: '
My name is {{$ctrl.name}}
',
+   *     bindings: {name: '@'}
+   *   });
+   *
+   *   myMod.component('myComp', {
+   *     templateUrl: 'views/my-comp.html',
+   *     controller: 'MyCtrl',
+   *     controllerAs: 'ctrl',
+   *     bindings: {name: '@'}
+   *   });
+   *
+   * ```
+   * For more examples, and an in-depth guide, see the {@link guide/component component guide}.

+ *
+ * In unit tests, if `angular-mocks.js` is loaded, this service is overridden by
+ * {@link ngMock.$exceptionHandler mock $exceptionHandler} which aids in testing.
+ *
+ * ## Example:
+ *
+ * ```js
+ *   angular.module('exceptionOverride', []).factory('$exceptionHandler', function() {
+ *     return function(exception, cause) {
+ *       exception.message += ' (caused by "' + cause + '")';

+ * This example will override the normal action of `$exceptionHandler`, to make angular
+ * exceptions fail hard when they happen, instead of just logging to the console.
+ *
+ * 

+ * Note, that code executed in event-listeners (even those registered using jqLite's `on`/`bind`
+ * methods) does not delegate exceptions to the {@link ng.$exceptionHandler $exceptionHandler}
+ * (unless executed during a digest).
+ *
+ * If you wish, you can manually delegate exceptions, e.g.

+     * @description
+     * The `$http` service is a core Angular service that facilitates communication with the remote
+     * HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest)
+     * object or via [JSONP](http://en.wikipedia.org/wiki/JSONP).
+     *
+     * For unit testing applications that use `$http` service, see
+     * {@link ngMock.$httpBackend $httpBackend mock}.
+     *
+     * For a higher level of abstraction, please check out the {@link ngResource.$resource
+     * $resource} service.
+     *
+     * The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
+     * the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
+     * it is important to familiarize yourself with these APIs and the guarantees they provide.
+     *
+     *
+     * ## General usage
+     * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} —
+     * that is used to generate an HTTP request and returns  a {@link ng.$q promise}.
+     *
+     * ```js
+     *   // Simple GET request example:
+     *   $http({
+     *     method: 'GET',
+     *     url: '/someUrl'
+     *   }).then(function successCallback(response) {
+     *       // this callback will be called asynchronously
+     *       // when the response is available
+     *     }, function errorCallback(response) {
+     *       // called asynchronously if an error occurs
+     *       // or server returns response with an error status.
+     *     });
+     * ```
+     *
+     * The response object has these properties:
+     *
+     *   - **data** – `{string|Object}` – The response body transformed with the transform
+     *     functions.
+     *   - **status** – `{number}` – HTTP status code of the response.
+     *   - **headers** – `{function([headerName])}` – Header getter function.
+     *   - **config** – `{Object}` – The configuration object that was used to generate the request.
+     *   - **statusText** – `{string}` – HTTP status text of the response.
+     *
+     * A response status code between 200 and 299 is considered a success status and
+     * will result in the success callback being called. Note that if the response is a redirect,
+     * XMLHttpRequest will transparently follow it, meaning that the error callback will not be
+     * called for such responses.
+     *
+     *
+     * ## Shortcut methods
+     *
+     * Shortcut methods are also available. All shortcut methods require passing in the URL, and
+     * request data must be passed in for POST/PUT requests. An optional config can be passed as the
+     * last argument.
+     *
+     * ```js
+     *   $http.get('/someUrl', config).then(successCallback, errorCallback);
+     *   $http.post('/someUrl', data, config).then(successCallback, errorCallback);
+     * ```
+     *
+     * Complete list of shortcut methods:
+     *
+     * - {@link ng.$http#get $http.get}
+     * - {@link ng.$http#head $http.head}
+     * - {@link ng.$http#post $http.post}
+     * - {@link ng.$http#put $http.put}
+     * - {@link ng.$http#delete $http.delete}
+     * - {@link ng.$http#jsonp $http.jsonp}
+     * - {@link ng.$http#patch $http.patch}
+     *
+     *
+     * ## Writing Unit Tests that use $http
+     * When unit testing (using {@link ngMock ngMock}), it is necessary to call
+     * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending
+     * request using trained responses.
+     *
+     * ```
+     * $httpBackend.expectGET(...);
+     * $http.get(...);
+     * $httpBackend.flush();
+     * ```
+     *
+     * ## Deprecation Notice
+     * 

+     *   The `$http` legacy promise methods `success` and `error` have been deprecated.
+     *   Use the standard `then` method instead.
+     *   If {@link $httpProvider#useLegacyPromiseExtensions `$httpProvider.useLegacyPromiseExtensions`} is set to
+     *   `false` then these methods will throw {@link $http:legacy `$http/legacy`} error.
+     * 

+     *
+     * ## Setting HTTP Headers
+     *
+     * The $http service will automatically add certain HTTP headers to all requests. These defaults
+     * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
+     * object, which currently contains this default configuration:
+     *
+     * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
+     *   - `Accept: application/json, text/plain, * / *`
+     * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
+     *   - `Content-Type: application/json`
+     * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
+     *   - `Content-Type: application/json`
+     *
+     * To add or overwrite these defaults, simply add or remove a property from these configuration
+     * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
+     * with the lowercased HTTP method name as the key, e.g.
+     * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.
+     *
+     * The defaults can also be set at runtime via the `$http.defaults` object in the same
+     * fashion. For example:
+     *
+     * ```
+     * module.run(function($http) {
+     *   $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w';
+     * });
+     * ```
+     *
+     * In addition, you can supply a `headers` property in the config object passed when
+     * calling `$http(config)`, which overrides the defaults without changing them globally.
+     *
+     * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,
+     * Use the `headers` property, setting the desired header to `undefined`. For example:
+     *
+     * ```js
+     * var req = {
+     *  method: 'POST',
+     *  url: 'http://example.com',
+     *  headers: {
+     *    'Content-Type': undefined
+     *  },
+     *  data: { test: 'test' }
+     * }
+     *
+     * $http(req).then(function(){...}, function(){...});
+     * ```
+     *
+     * ## Transforming Requests and Responses
+     *
+     * Both requests and responses can be transformed using transformation functions: `transformRequest`
+     * and `transformResponse`. These properties can be a single function that returns
+     * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,
+     * which allows you to `push` or `unshift` a new transformation function into the transformation chain.
+     *
+     * 

+     * **Note:** Angular does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline.
+     * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference).
+     * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest
+     * function will be reflected on the scope and in any templates where the object is data-bound.
+     * To prevent his, transform functions should have no side-effects.
+     * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return.
+     * 

+     *
+     * ### Default Transformations
+     *
+     * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and
+     * `defaults.transformResponse` properties. If a request does not provide its own transformations
+     * then these will be applied.
+     *
+     * You can augment or replace the default transformations by modifying these properties by adding to or
+     * replacing the array.
+     *
+     * Angular provides the following default transformations:
+     *
+     * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`):
+     *
+     * - If the `data` property of the request configuration object contains an object, serialize it
+     *   into JSON format.
+     *
+     * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`):
+     *
+     *  - If XSRF prefix is detected, strip it (see Security Considerations section below).
+     *  - If JSON response is detected, deserialize it using a JSON parser.
+     *
+     *
+     * ### Overriding the Default Transformations Per Request
+     *
+     * If you wish override the request/response transformations only for a single request then provide
+     * `transformRequest` and/or `transformResponse` properties on the configuration object passed
+     * into `$http`.
+     *
+     * Note that if you provide these properties on the config object the default transformations will be
+     * overwritten. If you wish to augment the default transformations then you must include them in your
+     * local transformation array.
+     *
+     * The following code demonstrates adding a new response transformation to be run after the default response
+     * transformations have been run.
+     *
+     * ```js
+     * function appendTransform(defaults, transform) {
+     *
+     *   // We can't guarantee that the default transformation is an array
+     *   defaults = angular.isArray(defaults) ? defaults : [defaults];
+     *
+     *   // Append the new transformation to the defaults
+     *   return defaults.concat(transform);
+     * }
+     *
+     * $http({
+     *   url: '...',
+     *   method: 'GET',
+     *   transformResponse: appendTransform($http.defaults.transformResponse, function(value) {
+     *     return doTransform(value);
+     *   })
+     * });
+     * ```
+     *
+     *
+     * ## Caching
+     *
+     * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must
+     * set the config.cache value or the default cache value to TRUE or to a cache object (created
+     * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes
+     * precedence over the default cache value.
+     *
+     * In order to:
+     *   * cache all responses - set the default cache value to TRUE or to a cache object
+     *   * cache a specific response - set config.cache value to TRUE or to a cache object
+     *
+     * If caching is enabled, but neither the default cache nor config.cache are set to a cache object,
+     * then the default `$cacheFactory($http)` object is used.
+     *
+     * The default cache value can be set by updating the
+     * {@link ng.$http#defaults `$http.defaults.cache`} property or the
+     * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property.
+     *
+     * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using
+     * the relevant cache object. The next time the same request is made, the response is returned
+     * from the cache without sending a request to the server.
+     *
+     * Take note that:
+     *
+     *   * Only GET and JSONP requests are cached.
+     *   * The cache key is the request URL including search parameters; headers are not considered.
+     *   * Cached responses are returned asynchronously, in the same way as responses from the server.
+     *   * If multiple identical requests are made using the same cache, which is not yet populated,
+     *     one request will be made to the server and remaining requests will return the same response.
+     *   * A cache-control header on the response does not affect if or how responses are cached.
+     *
+     *
+     * ## Interceptors
+     *
+     * Before you start creating interceptors, be sure to understand the
+     * {@link ng.$q $q and deferred/promise APIs}.
+     *
+     * For purposes of global error handling, authentication, or any kind of synchronous or
+     * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
+     * able to intercept requests before they are handed to the server and
+     * responses before they are handed over to the application code that
+     * initiated these requests. The interceptors leverage the {@link ng.$q
+     * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
+     *
+     * The interceptors are service factories that are registered with the `$httpProvider` by
+     * adding them to the `$httpProvider.interceptors` array. The factory is called and
+     * injected with dependencies (if specified) and returns the interceptor.
+     *
+     * There are two kinds of interceptors (and two kinds of rejection interceptors):
+     *
+     *   * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to
+     *     modify the `config` object or create a new one. The function needs to return the `config`
+     *     object directly, or a promise containing the `config` or a new `config` object.
+     *   * `requestError`: interceptor gets called when a previous interceptor threw an error or
+     *     resolved with a rejection.
+     *   * `response`: interceptors get called with http `response` object. The function is free to
+     *     modify the `response` object or create a new one. The function needs to return the `response`
+     *     object directly, or as a promise containing the `response` or a new `response` object.
+     *   * `responseError`: interceptor gets called when a previous interceptor threw an error or
+     *     resolved with a rejection.
+     *
+     *
+     * ```js
+     *   // register the interceptor as a service
+     *   $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
+     *     return {
+     *       // optional method
+     *       'request': function(config) {
+     *         // do something on success
+     *         return config;
+     *       },
+     *
+     *       // optional method
+     *      'requestError': function(rejection) {
+     *         // do something on error
+     *         if (canRecover(rejection)) {
+     *           return responseOrNewPromise
+     *         }
+     *         return $q.reject(rejection);
+     *       },
+     *
+     *
+     *
+     *       // optional method
+     *       'response': function(response) {

+     * ## Security Considerations
+     *
+     * When designing web applications, consider security threats from:
+     *
+     * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
+     * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
+     *
+     * Both server and the client must cooperate in order to eliminate these threats. Angular comes
+     * pre-configured with strategies that address these issues, but for this to work backend server
+     * cooperation is required.
+     *
+     * ### JSON Vulnerability Protection
+     *
+     * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
+     * allows third party website to turn your JSON resource URL into
+     * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To
+     * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
+     * Angular will automatically strip the prefix before processing it as JSON.
+     *
+     * For example if your server needs to return:
+     * ```js
+     * ['one','two']
+     * ```
+     *
+     * which is vulnerable to attack, your server can return:
+     * ```js
+     * )]}',
+     * ['one','two']
+     * ```
+     *
+     * Angular will strip the prefix, before processing the JSON.
+     *
+     *
+     * ### Cross Site Request Forgery (XSRF) Protection
+     *
+     * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by
+     * which the attacker can trick an authenticated user into unknowingly executing actions on your
+     * website. Angular provides a mechanism to counter XSRF. When performing XHR requests, the
+     * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP
+     * header (`X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read the
+     * cookie, your server can be assured that the XHR came from JavaScript running on your domain.
+     * The header will not be set for cross-domain requests.
+     *
+     * To take advantage of this, your server needs to set a token in a JavaScript readable session
+     * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
+     * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
+     * that only JavaScript running on your domain could have sent the request. The token must be
+     * unique for each user and must be verifiable by the server (to prevent the JavaScript from
+     * making up its own tokens). We recommend that the token is a digest of your site's
+     * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography))
+     * for added security.
+     *
+     * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName
+     * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,
+     * or the per-request config object.
+     *
+     * In order to prevent collisions in environments where multiple Angular apps share the
+     * same domain or subdomain, we recommend that each application uses unique cookie name.
+     *
+     * @param {object} config Object describing the request to be made and how it should be
+     *    processed. The object has following properties:
+     *
+     *    - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
+     *    - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.
+     *    - **params** – `{Object.}` – Map of strings or objects which will be serialized
+     *      with the `paramSerializer` and appended as GET parameters.
+     *    - **data** – `{string|Object}` – Data to be sent as the request message data.
+     *    - **headers** – `{Object}` – Map of strings or functions which return strings representing
+     *      HTTP headers to send to the server. If the return value of a function is null, the
+     *      header will not be sent. Functions accept a config object as an argument.
+     *    - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
+     *    - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
+     *    - **transformRequest** –
+     *      `{function(data, headersGetter)|Array.}` –
+     *      transform function or an array of such functions. The transform function takes the http
+     *      request body and headers and returns its transformed (typically serialized) version.
+     *      See {@link ng.$http#overriding-the-default-transformations-per-request
+     *      Overriding the Default Transformations}
+     *    - **transformResponse** –
+     *      `{function(data, headersGetter, status)|Array.}` –
+     *      transform function or an array of such functions. The transform function takes the http
+     *      response body, headers and status and returns its transformed (typically deserialized) version.
+     *      See {@link ng.$http#overriding-the-default-transformations-per-request
+     *      Overriding the Default Transformations}
+     *    - **paramSerializer** - `{string|function(Object):string}` - A function used to
+     *      prepare the string representation of request parameters (specified as an object).
+     *      If specified as string, it is interpreted as function registered with the
+     *      {@link $injector $injector}, which means you can create your own serializer
+     *      by registering it as a {@link auto.$provide#service service}.
+     *      The default serializer is the {@link $httpParamSerializer $httpParamSerializer};
+     *      alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike}
+     *    - **cache** – `{boolean|Object}` – A boolean value or object created with
+     *      {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response.
+     *      See {@link $http#caching $http Caching} for more information.
+     *    - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
+     *      that should abort the request when resolved.
+     *    - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the
+     *      XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
+     *      for more information.
+     *    - **responseType** - `{string}` - see
+     *      [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype).
+     *
+     * @returns {HttpPromise} Returns a {@link ng.$q `Promise}` that will be resolved to a response object
+     *                        when the request succeeds or fails.
+     *
+     *
+     * @property {Array.} pendingRequests Array of config objects for currently pending
+     *   requests. This is primarily meant to be used for debugging purposes.
+     *
+     *
+     * @example

+     *

+     *
+     * `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior.
+     *
+     * ####Escaped Interpolation
+     * $interpolate provides a mechanism for escaping interpolation markers. Start and end markers
+     * can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).
+     * It will be rendered as a regular start/end marker, and will not be interpreted as an expression
+     * or binding.
+     *
+     * This enables web-servers to prevent script injection attacks and defacing attacks, to some
+     * degree, while also enabling code examples to work without relying on the
+     * {@link ng.directive:ngNonBindable ngNonBindable} directive.
+     *
+     * **For security purposes, it is strongly encouraged that web servers escape user-supplied data,
+     * replacing angle brackets (<, >) with &lt; and &gt; respectively, and replacing all
+     * interpolation start/end markers with their escaped counterparts.**
+     *
+     * Escaped interpolation markers are only replaced with the actual interpolation markers in rendered
+     * output when the $interpolate service processes the text. So, for HTML elements interpolated
+     * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter
+     * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,
+     * this is typically useful only when user-data is used in rendering a template from the server, or
+     * when otherwise untrusted data is used by a directive.
+     *
+     * 
+     *  
+     *    

+     *      
{{apptitle}}: \{\{ username = "defaced value"; \}\}
+     *        

+     *      
{{username}} attempts to inject code which will deface the
+     *        application, but fails to accomplish their task, because the server has correctly
+     *        escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash)
+     *        characters.

+     *      
Instead, the result of the attempted script injection is visible, and can be removed
+     *        from the database by an administrator.

+      * Angular's wrapper for `window.setInterval`. The `fn` function is executed every `delay`
+      * milliseconds.
+      *
+      * The return value of registering an interval function is a promise. This promise will be
+      * notified upon each tick of the interval, and will be resolved after `count` iterations, or
+      * run indefinitely if `count` is not defined. The value of the notification will be the
+      * number of iterations that have run.
+      * To cancel an interval, call `$interval.cancel(promise)`.
+      *
+      * In tests you can use {@link ngMock.$interval#flush `$interval.flush(millis)`} to
+      * move forward by `millis` milliseconds and trigger any functions scheduled to run in that
+      * time.
+      *
+      * 

+      * **Note**: Intervals created by this service must be explicitly destroyed when you are finished
+      * with them.  In particular they are not automatically destroyed when a controller's scope or a
+      * directive's element are destroyed.
+      * You should take this into consideration and make sure to always cancel the interval at the
+      * appropriate moment.  See the example below for more details on how and when to do this.
+      * 

+      *
+      * @param {function()} fn A function that should be called repeatedly.
+      * @param {number} delay Number of milliseconds between each function call.
+      * @param {number=} [count=0] Number of times to repeat. If not set, or 0, will repeat
+      *   indefinitely.
+      * @param {boolean=} [invokeApply=true] If set to `false` skips model dirty checking, otherwise
+      *   will invoke `fn` within the {@link ng.$rootScope.Scope#$apply $apply} block.
+      * @param {...*=} Pass additional parameters to the executed function.
+      * @returns {promise} A promise which will be notified on each iteration.
+      *
+      * @example
+      * 
+      *

+// Sandboxing Angular Expressions
+// ------------------------------
+// Angular expressions are generally considered safe because these expressions only have direct
+// access to `$scope` and locals. However, one can obtain the ability to execute arbitrary JS code by
+// obtaining a reference to native JS functions such as the Function constructor.
+//
+// As an example, consider the following Angular expression:
+//
+//   {}.toString.constructor('alert("evil JS code")')
+//
+// This sandboxing technique is not perfect and doesn't aim to be. The goal is to prevent exploits
+// against the expression language, but not to prevent exploits that were enabled by exposing
+// sensitive JavaScript or browser APIs on Scope. Exposing such objects on a Scope is never a good
+// practice and therefore we are not even trying to protect against interaction with an object
+// explicitly exposed in this way.
+//
+// In general, it is not possible to access a Window object from an angular expression unless a
+// window or some DOM object that has a reference to window is published onto a Scope.
+// Similarly we prevent invocations of function known to be dangerous, as well as assignments to
+// native objects.
+//

+ * @requires $rootScope
+ *
+ * @description
+ * A service that helps you run functions asynchronously, and use their return values (or exceptions)
+ * when they are done processing.
+ *
+ * This is an implementation of promises/deferred objects inspired by
+ * [Kris Kowal's Q](https://github.com/kriskowal/q).
+ *
+ * $q can be used in two fashions --- one which is more similar to Kris Kowal's Q or jQuery's Deferred
+ * implementations, and the other which resembles ES6 (ES2015) promises to some degree.
+ *
+ * # $q constructor
+ *
+ * The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver`
+ * function as the first argument. This is similar to the native Promise implementation from ES6,
+ * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).
+ *
+ * While the constructor-style use is supported, not all of the supporting methods from ES6 promises are
+ * available yet.
+ *
+ * It can be used like so:
+ *
+ * ```js
+ *   // for the purpose of this example let's assume that variables `$q` and `okToGreet`
+ *   // are available in the current lexical scope (they could have been injected or passed in).
+ *
+ *   function asyncGreet(name) {
+ *     // perform some asynchronous operation, resolve or reject the promise when appropriate.
+ *     return $q(function(resolve, reject) {

+ * ```
+ *
+ * Note: progress/notify callbacks are not currently supported via the ES6-style interface.
+ *
+ * Note: unlike ES6 behavior, an exception thrown in the constructor function will NOT implicitly reject the promise.
+ *
+ * However, the more traditional CommonJS-style usage is still available, and documented below.
+ *
+ * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
+ * interface for interacting with an object that represents the result of an action that is
+ * performed asynchronously, and may or may not be finished at any given point in time.
+ *
+ * From the perspective of dealing with error handling, deferred and promise APIs are to
+ * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
+ *
+ * ```js
+ *   // for the purpose of this example let's assume that variables `$q` and `okToGreet`
+ *   // are available in the current lexical scope (they could have been injected or passed in).
+ *
+ *   function asyncGreet(name) {
+ *     var deferred = $q.defer();
+ *
+ *     setTimeout(function() {
+ *       deferred.notify('About to greet ' + name + '.');
+ *
+ *       if (okToGreet(name)) {
+ *         deferred.resolve('Hello, ' + name + '!');
+ *       } else {
+ *         deferred.reject('Greeting ' + name + ' is not allowed.');
+ *       }
+ *     }, 1000);
+ *
+ *     return deferred.promise;
+ *   }
+ *
+ *   var promise = asyncGreet('Robin Hood');
+ *   promise.then(function(greeting) {
+ *     alert('Success: ' + greeting);
+ *   }, function(reason) {
+ *     alert('Failed: ' + reason);
+ *   }, function(update) {
+ *     alert('Got notification: ' + update);
+ *   });
+ * ```
+ *
+ * At first it might not be obvious why this extra complexity is worth the trouble. The payoff
+ * comes in the way of guarantees that promise and deferred APIs make, see
+ * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.
+ *
+ * Additionally the promise api allows for composition that is very hard to do with the
+ * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
+ * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
+ * section on serial or parallel joining of promises.
+ *
+ * # The Deferred API
+ *
+ * A new instance of deferred is constructed by calling `$q.defer()`.
+ *
+ * The purpose of the deferred object is to expose the associated Promise instance as well as APIs
+ * that can be used for signaling the successful or unsuccessful completion, as well as the status
+ * of the task.
+ *
+ * **Methods**
+ *
+ * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
+ *   constructed via `$q.reject`, the promise will be rejected instead.
+ * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
+ *   resolving it with a rejection constructed via `$q.reject`.
+ * - `notify(value)` - provides updates on the status of the promise's execution. This may be called
+ *   multiple times before the promise is either resolved or rejected.
+ *
+ * **Properties**
+ *
+ * - promise – `{Promise}` – promise object associated with this deferred.
+ *
+ *
+ * # The Promise API
+ *
+ * A new promise instance is created when a deferred instance is created and can be retrieved by
+ * calling `deferred.promise`.
+ *
+ * The purpose of the promise object is to allow for interested parties to get access to the result
+ * of the deferred task when it completes.
+ *
+ * **Methods**
+ *
+ * - `then(successCallback, errorCallback, notifyCallback)` – regardless of when the promise was or
+ *   will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously
+ *   as soon as the result is available. The callbacks are called with a single argument: the result
+ *   or rejection reason. Additionally, the notify callback may be called zero or more times to
+ *   provide a progress indication, before the promise is resolved or rejected.
+ *
+ *   This method *returns a new promise* which is resolved or rejected via the return value of the
+ *   `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved
+ *   with the value which is resolved in that promise using
+ *   [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)).
+ *   It also notifies via the return value of the `notifyCallback` method. The promise cannot be
+ *   resolved or rejected from the notifyCallback method.
+ *
+ * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
+ *
+ * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise,
+ *   but to do so without modifying the final value. This is useful to release resources or do some
+ *   clean-up that needs to be done whether the promise was rejected or resolved. See the [full
+ *   specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for
+ *   more information.
+ *
+ * # Chaining promises
+ *
+ * Because calling the `then` method of a promise returns a new derived promise, it is easily
+ * possible to create a chain of promises:
+ *
+ * ```js
+ *   promiseB = promiseA.then(function(result) {
+ *     return result + 1;
+ *   });
+ *
+ *   // promiseB will be resolved immediately after promiseA is resolved and its value
+ *   // will be the result of promiseA incremented by 1
+ * ```
+ *
+ * It is possible to create chains of any length and since a promise can be resolved with another
+ * promise (which will defer its resolution further), it is possible to pause/defer resolution of
+ * the promises at any point in the chain. This makes it possible to implement powerful APIs like
+ * $http's response interceptors.
+ *
+ *
+ * # Differences between Kris Kowal's Q and $q
+ *
+ *  There are two main differences:
+ *
+ * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
+ *   mechanism in angular, which means faster propagation of resolution or rejection into your
+ *   models and avoiding unnecessary browser repaints, which would result in flickering UI.
+ * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
+ *   all the important functionality needed for common async tasks.
+ *
+ * # Testing
+ *
+ *  ```js
+ *    it('should simulate promise', inject(function($q, $rootScope) {
+ *      var deferred = $q.defer();
+ *      var promise = deferred.promise;
+ *      var resolvedValue;
+ *
+ *      promise.then(function(value) { resolvedValue = value; });
+ *      expect(resolvedValue).toBeUndefined();
+ *
+ *      // Simulate resolving of promise
+ *      deferred.resolve(123);
+ *      // Note that the 'then' function does not get called synchronously.
+ *      // This is because we want the promise API to always be async, whether or not
+ *      // it got called synchronously or asynchronously.
+ *      expect(resolvedValue).toBeUndefined();
+ *
+ *      // Propagate promise resolution to 'then' functions using $apply().
+ *      $rootScope.$apply();
+ *      expect(resolvedValue).toEqual(123);
+ *    }));
+ *  ```
+ *
+ * @param {function(function, function)} resolver Function which is responsible for resolving or
+ *   rejecting the newly created promise. The first parameter is a function which resolves the
+ *   promise, the second parameter is a function which rejects the promise.

+ * DESIGN NOTES
+ *
+ * The design decisions behind the scope are heavily favored for speed and memory consumption.
+ *
+ * The typical use of scope is to watch the expressions, which most of the time return the same
+ * value as last time so we optimize the operation.
+ *
+ * Closures construction is expensive in terms of speed as well as memory:
+ *   - No closures, instead use prototypical inheritance for API
+ *   - Internal state needs to be stored on scope directly, which means that private state is
+ *     exposed as $$____ properties
+ *
+ * Loop operations are optimized by using while(count--) { ... }
+ *   - This means that in order to keep the same order of execution as addition we have to add
+ *     items to the array at the beginning (unshift) instead of at the end (push)

+ * Child scopes are created and removed often

+       * Registers a `listener` callback to be executed whenever the `watchExpression` changes.
+       *
+       * - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest
+       *   $digest()} and should return the value that will be watched. (`watchExpression` should not change
+       *   its value when executed multiple times with the same input because it may be executed multiple
+       *   times by {@link ng.$rootScope.Scope#$digest $digest()}. That is, `watchExpression` should be
+       *   [idempotent](http://en.wikipedia.org/wiki/Idempotence).
+       * - The `listener` is called only when the value from the current `watchExpression` and the
+       *   previous call to `watchExpression` are not equal (with the exception of the initial run,
+       *   see below). Inequality is determined according to reference inequality,
+       *   [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators)
+       *    via the `!==` Javascript operator, unless `objectEquality == true`
+       *   (see next point)
+       * - When `objectEquality == true`, inequality of the `watchExpression` is determined
+       *   according to the {@link angular.equals} function. To save the value of the object for
+       *   later comparison, the {@link angular.copy} function is used. This therefore means that
+       *   watching complex objects will have adverse memory and performance implications.
+       * - The watch `listener` may change the model, which may trigger other `listener`s to fire.
+       *   This is achieved by rerunning the watchers until no changes are detected. The rerun
+       *   iteration limit is 10 to prevent an infinite loop deadlock.
+       *
+       *
+       * If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
+       * you can register a `watchExpression` function with no `listener`. (Be prepared for
+       * multiple calls to your `watchExpression` because it will execute multiple times in a
+       * single {@link ng.$rootScope.Scope#$digest $digest} cycle if a change is detected.)
+       *
+       * After a watcher is registered with the scope, the `listener` fn is called asynchronously
+       * (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
+       * watcher. In rare cases, this is undesirable because the listener is called when the result
+       * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
+       * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
+       * listener was called due to initialization.
+       *
+       *
+       *
+       * # Example
+       * ```js
+           // let's assume that scope was dependency injected as the $rootScope

+       * Shallow watches the properties of an object and fires whenever any of the properties change
+       * (for arrays, this implies watching the array items; for object maps, this implies watching
+       * the properties). If a change is detected, the `listener` callback is fired.
+       *
+       * - The `obj` collection is observed via standard $watch operation and is examined on every
+       *   call to $digest() to see if any items have been added, removed, or moved.
+       * - The `listener` is called whenever anything within the `obj` has changed. Examples include
+       *   adding, removing, and moving items belonging to an object or array.
+       *
+       *
+       * # Example
+       * ```js
+          $scope.names = ['igor', 'matias', 'misko', 'james'];
+          $scope.dataCount = 4;
+
+          $scope.$watchCollection('names', function(newNames, oldNames) {

+       * ```
+       *
+       *
+       * @param {string|function(scope)} obj Evaluated as {@link guide/expression expression}. The
+       *    expression value should evaluate to an object or an array which is observed on each
+       *    {@link ng.$rootScope.Scope#$digest $digest} cycle. Any shallow change within the
+       *    collection will trigger a call to the `listener`.
+       *
+       * @param {function(newCollection, oldCollection, scope)} listener a callback function called
+       *    when a change is detected.
+       *    - The `newCollection` object is the newly modified data obtained from the `obj` expression
+       *    - The `oldCollection` object is a copy of the former collection data.
+       *      Due to performance considerations, the`oldCollection` value is computed only if the
+       *      `listener` function declares two or more arguments.
+       *    - The `scope` argument refers to the current scope.
+       *
+       * @returns {function()} Returns a de-registration function for this listener. When the
+       *    de-registration function is executed, the internal watch operation is terminated.

+       * Processes all of the {@link ng.$rootScope.Scope#$watch watchers} of the current scope and
+       * its children. Because a {@link ng.$rootScope.Scope#$watch watcher}'s listener can change
+       * the model, the `$digest()` keeps calling the {@link ng.$rootScope.Scope#$watch watchers}
+       * until no more listeners are firing. This means that it is possible to get into an infinite
+       * loop. This function will throw `'Maximum iteration limit exceeded.'` if the number of
+       * iterations exceeds 10.
+       *
+       * Usually, you don't call `$digest()` directly in
+       * {@link ng.directive:ngController controllers} or in
+       * {@link ng.$compileProvider#directive directives}.
+       * Instead, you should call {@link ng.$rootScope.Scope#$apply $apply()} (typically from within
+       * a {@link ng.$compileProvider#directive directive}), which will force a `$digest()`.
+       *
+       * If you want to be notified whenever `$digest()` is called,
+       * you can register a `watchExpression` function with
+       * {@link ng.$rootScope.Scope#$watch $watch()} with no `listener`.
+       *
+       * In unit tests, you may need to call `$digest()` to simulate the scope life cycle.

+       * # Example
+       * ```js
+           var scope = ...;

+ *
+ * Typically, you would configure or override the {@link ng.$sceDelegate $sceDelegate} instead of
+ * the `$sce` service to customize the way Strict Contextual Escaping works in AngularJS.  This is
+ * because, while the `$sce` provides numerous shorthand methods, etc., you really only need to

+ * work because `$sce` delegates to `$sceDelegate` for these operations.
+ *
+ * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} to configure this service.
+ *
+ * The default instance of `$sceDelegate` should work out of the box with little pain.  While you
+ * can override it completely to change the behavior of `$sce`, the common case would
+ * involve configuring the {@link ng.$sceDelegateProvider $sceDelegateProvider} instead by setting

+ * `$sce` is a service that provides Strict Contextual Escaping services to AngularJS.
+ *
+ * # Strict Contextual Escaping
+ *
+ * Strict Contextual Escaping (SCE) is a mode in which AngularJS requires bindings in certain
+ * contexts to result in a value that is marked as safe to use for that context.  One example of
+ * such a context is binding arbitrary html controlled by the user via `ng-bind-html`.  We refer
+ * to these contexts as privileged or SCE contexts.
+ *
+ * As of version 1.2, Angular ships with SCE enabled by default.
+ *
+ * Note:  When enabled (the default), IE<11 in quirks mode is not supported.  In this mode, IE<11 allow
+ * one to execute arbitrary javascript by the use of the expression() syntax.  Refer
+ *  to learn more about them.
+ * You can ensure your document is in standards mode and not quirks mode by adding ``
+ * to the top of your HTML document.
+ *
+ * SCE assists in writing code in way that (a) is secure by default and (b) makes auditing for
+ * security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
+ *
+ * Here's an example of a binding in a privileged context:
+ *
+ * ```
+ * 
+ * 

+ * ```
+ *
+ * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user.  With SCE
+ * disabled, this application allows the user to render arbitrary HTML into the DIV.
+ * In a more realistic example, one may be rendering user comments, blog articles, etc. via
+ * bindings.  (HTML is just one example of a context where rendering user controlled input creates
+ * security vulnerabilities.)
+ *
+ * For the case of HTML, you might use a library, either on the client side, or on the server side,
+ * to sanitize unsafe HTML before binding to the value and rendering it in the document.
+ *
+ * How would you ensure that every place that used these types of bindings was bound to a value that
+ * was sanitized by your library (or returned as safe for rendering by your server?)  How can you
+ * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
+ * properties/fields and forgot to update the binding to the sanitized value?
+ *
+ * To be secure by default, you want to ensure that any such bindings are disallowed unless you can
+ * determine that something explicitly says it's safe to use a value for binding in that
+ * context.  You can then audit your code (a simple grep would do) to ensure that this is only done
+ * for those values that you can easily tell are safe - because they were received from your server,
+ * sanitized by your library, etc.  You can organize your codebase to help with this - perhaps
+ * allowing only the files in a specific directory to do this.  Ensuring that the internal API
+ * exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task.
+ *
+ * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}
+ * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to
+ * obtain values that will be accepted by SCE / privileged contexts.
+ *
+ *
+ * ## How does it work?
+ *
+ * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
+ * $sce.getTrusted(context, value)} rather than to the value directly.  Directives use {@link
+ * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the
+ * {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals.
+ *
+ * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
+ * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}.  Here's the actual code (slightly
+ * simplified):
+ *
+ * ```
+ * var ngBindHtmlDirective = ['$sce', function($sce) {
+ *   return function(scope, element, attr) {
+ *     scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
+ *       element.html(value || '');
+ *     });
+ *   };
+ * }];
+ * ```
+ *
+ * ## Impact on loading templates
+ *
+ * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
+ * `templateUrl`'s specified by {@link guide/directive directives}.
+ *
+ * By default, Angular only loads templates from the same domain and protocol as the application
+ * document.  This is done by calling {@link ng.$sce#getTrustedResourceUrl
+ * $sce.getTrustedResourceUrl} on the template URL.  To load templates from other domains and/or
+ * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist
+ * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.
+ *
+ * *Please note*:
+ * The browser's
+ * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
+ * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
+ * policy apply in addition to this and may further restrict whether the template is successfully
+ * loaded.  This means that without the right CORS policy, loading templates from a different domain
+ * won't work on all browsers.  Also, loading templates from `file://` URL does not work on some
+ * browsers.
+ *
+ * ## This feels like too much overhead
+ *
+ * It's important to remember that SCE only applies to interpolation expressions.
+ *
+ * If your expressions are constant literals, they're automatically trusted and you don't need to
+ * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g.
+ * `
`) just works.
+ *
+ * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them
+ * through {@link ng.$sce#getTrusted $sce.getTrusted}.  SCE doesn't play a role here.
+ *
+ * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
+ * templates in `ng-include` from your application's domain without having to even know about SCE.
+ * It blocks loading templates from other domains or loading templates over http from an https
+ * served document.  You can change these by setting your own custom {@link
+ * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link
+ * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.
+ *
+ * This significantly reduces the overhead.  It is far easier to pay the small overhead and have an
+ * application that's secure and can be audited to verify that with much more ease than bolting
+ * security onto an application later.
+ *
+ * 
+ * ## What trusted context types are supported?
+ *
+ * | Context             | Notes          |
+ * |---------------------|----------------|
+ * | `$sce.HTML`         | For HTML that's safe to source into the application.  The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. |
+ * | `$sce.CSS`          | For CSS that's safe to source into the application.  Currently unused.  Feel free to use it in your own directives. |
+ * | `$sce.URL`          | For URLs that are safe to follow as links.  Currently unused (`
Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. |
+ * | `$sce.JS`           | For JavaScript that is safe to execute in your application's context.  Currently unused.  Feel free to use it in your own directives. |
+ *
+ * ## Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} 
+ *
+ *  Each element in these arrays must be one of the following:
+ *
+ *  - **'self'**
+ *    - The special **string**, `'self'`, can be used to match against all URLs of the **same
+ *      domain** as the application document using the **same protocol**.
+ *  - **String** (except the special value `'self'`)
+ *    - The string is matched against the full *normalized / absolute URL* of the resource
+ *      being tested (substring matches are not good enough.)
+ *    - There are exactly **two wildcard sequences** - `*` and `**`.  All other characters
+ *      match themselves.
+ *    - `*`: matches zero or more occurrences of any character other than one of the following 6
+ *      characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'.  It's a useful wildcard for use
+ *      in a whitelist.
+ *    - `**`: matches zero or more occurrences of *any* character.  As such, it's not
+ *      appropriate for use in a scheme, domain, etc. as it would match too much.  (e.g.
+ *      http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might
+ *      not have been the intention.)  Its usage at the very end of the path is ok.  (e.g.
+ *      http://foo.example.com/templates/**).
+ *  - **RegExp** (*see caveat below*)
+ *    - *Caveat*:  While regular expressions are powerful and offer great flexibility,  their syntax
+ *      (and all the inevitable escaping) makes them *harder to maintain*.  It's easy to
+ *      accidentally introduce a bug when one updates a complex expression (imho, all regexes should
+ *      have good test coverage).  For instance, the use of `.` in the regex is correct only in a
+ *      small number of cases.  A `.` character in the regex used when matching the scheme or a
+ *      subdomain could be matched against a `:` or literal `.` that was likely not intended.   It
+ *      is highly recommended to use the string patterns and only fall back to regular expressions
+ *      as a last resort.
+ *    - The regular expression must be an instance of RegExp (i.e. not a string.)  It is
+ *      matched against the **entire** *normalized / absolute URL* of the resource being tested
+ *      (even when the RegExp did not have the `^` and `$` codes.)  In addition, any flags
+ *      present on the RegExp (such as multiline, global, ignoreCase) are ignored.
+ *    - If you are generating your JavaScript from some other templating engine (not
+ *      recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),
+ *      remember to escape your regular expression (and be aware that you might need more than
+ *      one level of escaping depending on your templating engine and the way you interpolated
+ *      the value.)  Do make use of your platform's escaping mechanism as it might be good
+ *      enough before coding your own.  E.g. Ruby has
+ *      [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)
+ *      and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).
+ *      Javascript lacks a similar built in function for escaping.  Take a look at Google
+ *      Closure library's [goog.string.regExpEscape(s)](
+ *      http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).
+ *
+ * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example.

+ * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {

+  /* Design notes on the default implementation for SCE.
+   *
+   * The API contract for the SCE delegate
+   * -------------------------------------
+   * The SCE delegate object must provide the following 3 methods:
+   *
+   * - trustAs(contextEnum, value)
+   *     This method is used to tell the SCE service that the provided value is OK to use in the
+   *     contexts specified by contextEnum.  It must return an object that will be accepted by
+   *     getTrusted() for a compatible contextEnum and return this value.
+   *
+   * - valueOf(value)
+   *     For values that were not produced by trustAs(), return them as is.  For values that were
+   *     produced by trustAs(), return the corresponding input value to trustAs.  Basically, if
+   *     trustAs is wrapping the given values into some type, this operation unwraps it when given
+   *     such a value.
+   *
+   * - getTrusted(contextEnum, value)
+   *     This function should return the a value that is safe to use in the context specified by
+   *     contextEnum or throw and exception otherwise.
+   *
+   * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
+   * opaque or wrapped in some holder object.  That happens to be an implementation detail.  For
+   * instance, an implementation could maintain a registry of all trusted objects by context.  In
+   * such a case, trustAs() would return the same object that was passed in.  getTrusted() would
+   * return the same object passed in if it was found in the registry under a compatible context or
+   * throw an exception otherwise.  An implementation might only wrap values some of the time based
+   * on some criteria.  getTrusted() might return a value and not throw an exception for special
+   * constants or objects even if not wrapped.  All such implementations fulfill this contract.
+   *
+   *
+   * A note on the inheritance model for SCE contexts
+   * ------------------------------------------------
+   * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types.  This
+   * is purely an implementation details.
+   *
+   * The contract is simply this:
+   *
+   *     getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
+   *     will also succeed.
+   *
+   * Inheritance happens to capture this in a natural way.  In some future, we
+   * may not use inheritance anymore.  That is OK because no code outside of
+   * sce.js and sceSpecs.js would need to be aware of this detail.

+ *
+ * Implementation Notes for non-IE browsers
+ * ----------------------------------------
+ * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
+ * results both in the normalizing and parsing of the URL.  Normalizing means that a relative
+ * URL will be resolved into an absolute URL in the context of the application document.
+ * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
+ * properties are all populated to reflect the normalized URL.  This approach has wide
+ * compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc.  See
+ * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
+ *
+ * Implementation Notes for IE
+ * ---------------------------
+ * IE <= 10 normalizes the URL when assigned to the anchor node similar to the other
+ * browsers.  However, the parsed components will not be set if the URL assigned did not specify
+ * them.  (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.)  We
+ * work around that by performing the parsing in a 2nd step by taking a previously normalized
+ * URL (e.g. by assigning to a.href) and assigning it a.href again.  This correctly populates the
+ * properties such as protocol, hostname, port, etc.

+ * Filters are just functions which transform input to an output. However filters need to be
+ * Dependency Injected. To achieve this a filter definition consists of a factory function which is
+ * annotated with dependencies and is responsible for creating a filter function.
+ *
+ * 

+ * **Note:** Filter names must be valid angular {@link expression} identifiers, such as `uppercase` or `orderBy`.
+ * Names with special characters, such as hyphens and dots, are not allowed. If you wish to namespace
+ * your filters, then you can use capitalization (`myappSubsectionFilterx`) or underscores
+ * (`myapp_subsection_filterx`).
+ * 

+ *
+ * ```js
+ *   // Filter registration
+ *   function MyModule($provide, $filterProvider) {
+ *     // create a service to demonstrate injection (not always needed)
+ *     $provide.value('greet', function(name){
+ *       return 'Hello ' + name + '!';
+ *     });
+ *
+ *     // register a filter factory which uses the
+ *     // greet service to demonstrate DI.
+ *     $filterProvider.register('greet', function(greet){
+ *       // return the filter function which uses the greet service
+ *       // to generate salutation
+ *       return function(text) {

+ *         return text && greet(text) || text;
+ *       };
+ *     });
+ *   }
+ * ```
+ *
+ * The filter function is registered with the `$injector` under the filter name suffix with
+ * `Filter`.
+ *
+ * ```js
+ *   it('should be the same instance', inject(

+ * @ngdoc filter
+ * @name filter
+ * @kind function
+ *
+ * @description
+ * Selects a subset of items from `array` and returns it as a new array.
+ *
+ * @param {Array} array The source array.
+ * @param {string|Object|function()} expression The predicate to be used for selecting items from
+ *   `array`.
+ *
+ *   Can be one of:
+ *
+ *   - `string`: The string is used for matching against the contents of the `array`. All strings or
+ *     objects with string properties in `array` that match this string will be returned. This also
+ *     applies to nested object properties.
+ *     The predicate can be negated by prefixing the string with `!`.
+ *
+ *   - `Object`: A pattern object can be used to filter specific properties on objects contained
+ *     by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
+ *     which have property `name` containing "M" and property `phone` containing "1". A special
+ *     property name `$` can be used (as in `{$:"text"}`) to accept a match against any
+ *     property of the object or its nested object properties. That's equivalent to the simple
+ *     substring match with a `string` as described above. The predicate can be negated by prefixing
+ *     the string with `!`.
+ *     For example `{name: "!M"}` predicate will return an array of items which have property `name`
+ *     not containing "M".
+ *
+ *     Note that a named property will match properties on the same level only, while the special
+ *     `$` property will match properties on the same level or deeper. E.g. an array item like
+ *     `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but
+ *     **will** be matched by `{$: 'John'}`.
+ *
+ *   - `function(value, index, array)`: A predicate function can be used to write arbitrary filters.
+ *     The function is called for each element of the array, with the element, its index, and
+ *     the entire array itself as arguments.
+ *
+ *     The final result is an array of those elements that the predicate returned true for.
+ *
+ * @param {function(actual, expected)|true|undefined} comparator Comparator which is used in
+ *     determining if the expected value (from the filter expression) and actual value (from
+ *     the object in the array) should be considered a match.
+ *
+ *   Can be one of:
+ *
+ *   - `function(actual, expected)`:
+ *     The function will be given the object value and the predicate value to compare and
+ *     should return true if both values should be considered equal.
+ *
+ *   - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`.
+ *     This is essentially strict comparison of expected and actual.
+ *
+ *   - `false|undefined`: A short hand for a function which will look for a substring match in case
+ *     insensitive way.
+ *
+ *     Primitive values are converted to strings. Objects are not compared against primitives,
+ *     unless they have a custom `toString` method (e.g. `Date` objects).

+ * @ngdoc filter
+ * @name orderBy
+ * @kind function
+ *
+ * @description
+ * Orders a specified `array` by the `expression` predicate. It is ordered alphabetically
+ * for strings and numerically for numbers. Note: if you notice numbers are not being sorted
+ * as expected, make sure they are actually being saved as numbers and not strings.
+ * Array-like values (e.g. NodeLists, jQuery objects, TypedArrays, Strings, etc) are also supported.
+ *
+ * @param {Array} array The array (or array-like object) to sort.
+ * @param {function(*)|string|Array.<(function(*)|string)>=} expression A predicate to be
+ *    used by the comparator to determine the order of elements.
+ *
+ *    Can be one of:
+ *
+ *    - `function`: Getter function. The result of this function will be sorted using the
+ *      `<`, `===`, `>` operator.
+ *    - `string`: An Angular expression. The result of this expression is used to compare elements
+ *      (for example `name` to sort by a property called `name` or `name.substr(0, 3)` to sort by
+ *      3 first characters of a property called `name`). The result of a constant expression
+ *      is interpreted as a property name to be used in comparisons (for example `"special name"`
+ *      to sort object by the value of their `special name` property). An expression can be
+ *      optionally prefixed with `+` or `-` to control ascending or descending sort order
+ *      (for example, `+name` or `-name`). If no property is provided, (e.g. `'+'`) then the array
+ *      element itself is used to compare where sorting.
+ *    - `Array`: An array of function or string predicates. The first predicate in the array
+ *      is used for sorting, but when two items are equivalent, the next predicate is used.
+ *
+ *    If the predicate is missing or empty then it defaults to `'+'`.
+ *
+ * @param {boolean=} reverse Reverse the order of the array.
+ * @returns {Array} Sorted copy of the source array.
+ *
+ *
+ * @example
+ * The example below demonstrates a simple ngRepeat, where the data is sorted
+ * by age in descending order (predicate is set to `'-age'`).
+ * `reverse` is not set, which means it defaults to `false`.

+ *
+ * @description
+ * Directive that instantiates
+ * {@link form.FormController FormController}.
+ *
+ * If the `name` attribute is specified, the form controller is published onto the current scope under
+ * this name.
+ *
+ * # Alias: {@link ng.directive:ngForm `ngForm`}
+ *
+ * In Angular, forms can be nested. This means that the outer form is valid when all of the child
+ * forms are valid as well. However, browsers do not allow nesting of `` elements, so
+ * Angular provides the {@link ng.directive:ngForm `ngForm`} directive, which behaves identically to
+ * `form` but can be nested. Nested forms can be useful, for example, if the validity of a sub-group
+ * of controls needs to be determined.
+ *
+ * # CSS classes
+ *  - `ng-valid` is set if the form is valid.
+ *  - `ng-invalid` is set if the form is invalid.
+ *  - `ng-pending` is set if the form is pending.
+ *  - `ng-pristine` is set if the form is pristine.
+ *  - `ng-dirty` is set if the form is dirty.
+ *  - `ng-submitted` is set if the form was submitted.
+ *
+ * Keep in mind that ngAnimate can detect each of these classes when added and removed.
+ *
+ *
+ * # Submitting a form and preventing the default action
+ *
+ * Since the role of forms in client-side Angular applications is different than in classical
+ * roundtrip apps, it is desirable for the browser not to translate the form submission into a full
+ * page reload that sends the data to the server. Instead some javascript logic should be triggered
+ * to handle the form submission in an application-specific way.
+ *
+ * For this reason, Angular prevents the default action (form submission to the server) unless the
+ * `` element has an `action` attribute specified.
+ *
+ * You can use one of the following two ways to specify what javascript method should be called when
+ * a form is submitted:
+ *
+ * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element
+ * - {@link ng.directive:ngClick ngClick} directive on the first
+  *  button or input field of type submit (input[type=submit])
+ *
+ * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}
+ * or {@link ng.directive:ngClick ngClick} directives.
+ * This is because of the following form submission rules in the HTML specification:
+ *
+ * - If a form has only one input field then hitting enter in this field triggers form submit
+ * (`ngSubmit`)
+ * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter
+ * doesn't trigger submit
+ * - if a form has one or more input fields and one or more buttons or input[type=submit] then
+ * hitting enter in any of the input fields will trigger the click handler on the *first* button or
+ * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)
+ *
+ * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is
+ * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
+ * to have access to the updated model.
+ *
+ * ## Animation Hooks
+ *
+ * Animations in ngForm are triggered when any of the associated CSS classes are added and removed.
+ * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any
+ * other validations that are performed within the form. Animations in ngForm are similar to how
+ * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well
+ * as JS animations.
+ *
+ * The following example shows a simple way to utilize CSS transitions to style a form element
+ * that has been rendered as invalid after it has been validated:
+ *
+ * 
+ * //be sure to include ngAnimate as a module to hook into more
+ * //advanced animations
+ * .my-form {
+ *   transition:0.5s linear all;
+ *   background: white;
+ * }
+ * .my-form.ng-invalid {
+ *   background: red;
+ *   color:white;
+ * }
+ * 

+ *
+ * @example
+    
+      
+       
+       
+       
+         userType: 
+         Required!

+         userType = {{userType}}

+         myForm.input.$valid = {{myForm.input.$valid}}

+         myForm.input.$error = {{myForm.input.$error}}

+         myForm.$valid = {{myForm.$valid}}

+         myForm.$error.required = {{!!myForm.$error.required}}

+        
+      
+      
+        it('should initialize to model', function() {
+          var userType = element(by.binding('userType'));
+          var valid = element(by.binding('myForm.input.$valid'));
+
+          expect(userType.getText()).toContain('guest');
+          expect(valid.getText()).toContain('true');
+        });
+
+        it('should be invalid if empty', function() {

+          expect(valid.getText()).toContain('false');

+   *
+   * @param {string} ngModel Assignable angular expression to data-bind to.
+   * @param {string=} name Property name of the form under which the control is published.
+   * @param {string=} required Adds `required` validation error key if the value is not entered.
+   * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
+   *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
+   *    `required` when you want to data-bind to the `required` attribute.
+   * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
+   *    minlength.
+   * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
+   *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
+   *    any length.
+   * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
+   *    that contains the regular expression body that will be converted to a regular expression
+   *    as in the ngPattern directive.
+   * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
+   *    does not match a RegExp found by evaluating the Angular expression given in the attribute value.
+   *    If the expression evaluates to a RegExp object, then this is used directly.
+   *    If the expression evaluates to a string, then it will be converted to a RegExp
+   *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
+   *    `new RegExp('^abc$')`.

+   *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
+   *    start at the index of the last search's match, thus not taking the whole input value into
+   *    account.
+   * @param {string=} ngChange Angular expression to be executed when input changes due to user
+   *    interaction with the input element.
+   * @param {boolean=} [ngTrim=true] If set to false Angular will not automatically trim the input.

+     * Input with date validation and transformation. In browsers that do not yet support
+     * the HTML5 date input, a text element will be used. In that case, text must be entered in a valid ISO-8601
+     * date format (yyyy-MM-dd), for example: `2009-01-06`. Since many
+     * modern browsers do not yet support this input type, it is important to provide cues to users on the
+     * expected input format via a placeholder or label.
+     *
+     * The model must always be a Date object, otherwise Angular will throw an error.
+     * Invalid `Date` objects (dates whose `getTime()` is `NaN`) will be rendered as an empty string.
+     *
+     * The timezone to be used to read/write the `Date` instance in the model can be defined using
+     * {@link ng.directive:ngModelOptions ngModelOptions}. By default, this is the timezone of the browser.
+     *
+     * @param {string} ngModel Assignable angular expression to data-bind to.
+     * @param {string=} name Property name of the form under which the control is published.
+     * @param {string=} min Sets the `min` validation error key if the value entered is less than `min`. This must be a
+     *   valid ISO date string (yyyy-MM-dd). You can also use interpolation inside this attribute
+     *   (e.g. `min="{{minDate | date:'yyyy-MM-dd'}}"`). Note that `min` will also add native HTML5
+     *   constraint validation.
+     * @param {string=} max Sets the `max` validation error key if the value entered is greater than `max`. This must be
+     *   a valid ISO date string (yyyy-MM-dd). You can also use interpolation inside this attribute
+     *   (e.g. `max="{{maxDate | date:'yyyy-MM-dd'}}"`). Note that `max` will also add native HTML5
+     *   constraint validation.
+     * @param {(date|string)=} ngMin Sets the `min` validation constraint to the Date / ISO date string
+     *   the `ngMin` expression evaluates to. Note that it does not set the `min` attribute.
+     * @param {(date|string)=} ngMax Sets the `max` validation constraint to the Date / ISO date string
+     *   the `ngMax` expression evaluates to. Note that it does not set the `max` attribute.
+     * @param {string=} required Sets `required` validation error key if the value is not entered.
+     * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to

+   * @name input[number]
+   *
+   * @description
+   * Text input with number validation and transformation. Sets the `number` validation
+   * error if not a valid number.
+   *
+   * 

+   * The model must always be of type `number` otherwise Angular will throw an error.
+   * Be aware that a string containing a number is not enough. See the {@link ngModel:numfmt}
+   * error docs for more information and an example of how to convert your model if necessary.
+   * 

+   *
+   * ## Issues with HTML5 constraint validation
+   *
+   * In browsers that follow the
+   * [HTML5 specification](https://html.spec.whatwg.org/multipage/forms.html#number-state-%28type=number%29),
+   * `input[number]` does not work as expected with {@link ngModelOptions `ngModelOptions.allowInvalid`}.
+   * If a non-number is entered in the input, the browser will report the value as an empty string,
+   * which means the view / model values in `ngModel` and subsequently the scope value
+   * will also be an empty string.
+   *
+   *
+   * @param {string} ngModel Assignable angular expression to data-bind to.
+   * @param {string=} name Property name of the form under which the control is published.
+   * @param {string=} min Sets the `min` validation error key if the value entered is less than `min`.
+   * @param {string=} max Sets the `max` validation error key if the value entered is greater than `max`.
+   * @param {string=} required Sets `required` validation error key if the value is not entered.
+   * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
+   *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
+   *    `required` when you want to data-bind to the `required` attribute.
+   * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
+   *    minlength.
+   * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
+   *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
+   *    any length.
+   * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
+   *    that contains the regular expression body that will be converted to a regular expression
+   *    as in the ngPattern directive.
+   * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
+   *    does not match a RegExp found by evaluating the Angular expression given in the attribute value.
+   *    If the expression evaluates to a RegExp object, then this is used directly.
+   *    If the expression evaluates to a string, then it will be converted to a RegExp
+   *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
+   *    `new RegExp('^abc$')`.

+   *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
+   *    start at the index of the last search's match, thus not taking the whole input value into
