+ * @ngdoc module
+ * @name ngAnimate
+ * @description
+ *
+ * The `ngAnimate` module provides support for JavaScript, CSS3 transition and CSS3 keyframe animation hooks within existing core and custom directives.
+ *
+ * <div doc-module-components="ngAnimate"></div>
+ *
+ * # Usage
+ *
+ * To see animations in action, all that is required is to define the appropriate CSS classes
+ * or to register a JavaScript animation via the `myModule.animation()` function. The directives that support animation automatically are:
+ * `ngRepeat`, `ngInclude`, `ngIf`, `ngSwitch`, `ngShow`, `ngHide`, `ngView` and `ngClass`. Custom directives can take advantage of animation
+ * by using the `$animate` service.
+ *
+ * Below is a more detailed breakdown of the supported animation events provided by pre-existing ng directives:
+ *
+ * | 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 |
+ *
+ * You can find out more information about animations upon visiting each directive page.
+ *
+ * Below is an example of how to apply animations to a directive that supports animation hooks:
+ *
+ * ```html
+ * <style type="text/css">
+ * .slide.ng-enter, .slide.ng-leave {
+ * -webkit-transition:0.5s linear all;
+ * transition:0.5s linear all;
+ * }
+ *
+ * .slide.ng-enter { } /&#42; starting animations for enter &#42;/
+ * .slide.ng-enter.ng-enter-active { } /&#42; terminal animations for enter &#42;/
+ * .slide.ng-leave { } /&#42; starting animations for leave &#42;/
+ * .slide.ng-leave.ng-leave-active { } /&#42; terminal animations for leave &#42;/
+ * </style>
+ *
+ * <!--
+ * the animate service will automatically add .ng-enter and .ng-leave to the element
+ * to trigger the CSS transition/animations
+ * -->
+ * <ANY class="slide" ng-include="..."></ANY>
+ * ```
+ *
+ * Keep in mind that, by default, if an animation is running, any child elements cannot be animated
+ * until the parent element's animation has completed. This blocking feature can be overridden by
+ * placing the `ng-animate-children` attribute on a parent container tag.
+ *
+ * ```html
+ * <div class="slide-animation" ng-if="on" ng-animate-children>
+ * <div class="fade-animation" ng-if="on">
+ * <div class="explode-animation" ng-if="on">
+ * ...
+ * </div>
+ * </div>
+ * </div>
+ * ```
+ *
+ * When the `on` expression value changes and an animation is triggered then each of the elements within
+ * will all animate without the block being applied to child elements.
+ *
+ * ## Are animations run when the application starts?
+ * No they are not. When an application is bootstrapped Angular will disable animations from running to avoid
+ * a frenzy of animations from being triggered as soon as the browser has rendered the screen. For this to work,
+ * Angular will wait for two digest cycles until enabling animations. From there on, any animation-triggering
+ * layout changes in the application will trigger animations as normal.
+ *
+ * In addition, upon bootstrap, if the routing system or any directives or load remote data (via $http) then Angular
+ * will automatically extend the wait time to enable animations once **all** of the outbound HTTP requests
+ * are complete.
+ *
+ * ## CSS-defined Animations
+ * The animate service will automatically apply two CSS classes to the animated element and these two CSS classes
+ * are designed to contain the start and end CSS styling. Both CSS transitions and keyframe animations are supported
+ * and can be used to play along with this naming structure.
+ *
+ * The following code below demonstrates how to perform animations using **CSS transitions** with Angular:
+ *
+ * ```html
+ * <style type="text/css">
+ * /&#42;
+ * The animate class is apart of the element and the ng-enter class
+ * is attached to the element once the enter animation event is triggered
+ * &#42;/
+ * .reveal-animation.ng-enter {
+ * -webkit-transition: 1s linear all; /&#42; Safari/Chrome &#42;/
+ * transition: 1s linear all; /&#42; All other modern browsers and IE10+ &#42;/
+ *
+ * /&#42; The animation preparation code &#42;/
+ * opacity: 0;
+ * }
+ *
+ * /&#42;
+ * Keep in mind that you want to combine both CSS
+ * classes together to avoid any CSS-specificity
+ * conflicts
+ * &#42;/
+ * .reveal-animation.ng-enter.ng-enter-active {
+ * /&#42; The animation code itself &#42;/
+ * opacity: 1;
+ * }
+ * </style>
+ *
+ * <div class="view-container">
+ * <div ng-view class="reveal-animation"></div>
+ * </div>
+ * ```
+ *
+ * The following code below demonstrates how to perform animations using **CSS animations** with Angular:
+ *
+ * ```html
+ * <style type="text/css">
+ * .reveal-animation.ng-enter {
+ * -webkit-animation: enter_sequence 1s linear; /&#42; Safari/Chrome &#42;/
+ * animation: enter_sequence 1s linear; /&#42; IE10+ and Future Browsers &#42;/
+ * }
+ * @-webkit-keyframes enter_sequence {
+ * from { opacity:0; }
+ * to { opacity:1; }
+ * }
+ * @keyframes enter_sequence {
+ * from { opacity:0; }
+ * to { opacity:1; }
+ * }
+ * </style>
+ *
+ * <div class="view-container">
+ * <div ng-view class="reveal-animation"></div>
+ * </div>
+ * ```
+ *
+ * Both CSS3 animations and transitions can be used together and the animate service will figure out the correct duration and delay timing.
+ *
+ * Upon DOM mutation, the event class is added first (something like `ng-enter`), then the browser prepares itself to add
+ * the active class (in this case `ng-enter-active`) which then triggers the animation. The animation module will automatically
+ * detect the CSS code to determine when the animation ends. Once the animation is over then both CSS classes will be
+ * removed from the DOM. If a browser does not support CSS transitions or CSS animations then the animation will start and end
+ * immediately resulting in a DOM element that is at its final state. This final state is when the DOM element
+ * has no CSS transition/animation classes applied to it.
+ *
+ * ### Structural transition animations
+ *
+ * Structural transitions (such as enter, leave and move) will always apply a `0s none` transition
+ * value to force the browser into rendering the styles defined in the setup (`.ng-enter`, `.ng-leave`
+ * or `.ng-move`) class. This means that any active transition animations operating on the element
+ * will be cut off to make way for the enter, leave or move animation.
+ *
+ * ### Class-based transition animations
+ *
+ * Class-based transitions refer to transition animations that are triggered when a CSS class is
+ * added to or removed from the element (via `$animate.addClass`, `$animate.removeClass`,
+ * `$animate.setClass`, or by directives such as `ngClass`, `ngModel` and `form`).
+ * They are different when compared to structural animations since they **do not cancel existing
+ * animations** nor do they **block successive transitions** from rendering on the same element.
+ * This distinction allows for **multiple class-based transitions** to be performed on the same element.
+ *
+ * In addition to ngAnimate supporting the default (natural) functionality of class-based transition
+ * animations, ngAnimate also decorates the element with starting and ending CSS classes to aid the
+ * developer in further styling the element throughout the transition animation. Earlier versions
+ * of ngAnimate may have caused natural CSS transitions to break and not render properly due to
+ * $animate temporarily blocking transitions using `0s none` in order to allow the setup CSS class
+ * (the `-add` or `-remove` class) to be applied without triggering an animation. However, as of
+ * **version 1.3**, this workaround has been removed with ngAnimate and all non-ngAnimate CSS
+ * class transitions are compatible with ngAnimate.
+ *
+ * There is, however, one special case when dealing with class-based transitions in ngAnimate.
+ * When rendering class-based transitions that make use of the setup and active CSS classes
+ * (e.g. `.fade-add` and `.fade-add-active` for when `.fade` is added) be sure to define
+ * the transition value **on the active CSS class** and not the setup class.
+ *
+ * ```css
+ * .fade-add {
+ * /&#42; remember to place a 0s transition here
+ * to ensure that the styles are applied instantly
+ * even if the element already has a transition style &#42;/
+ * transition:0s linear all;
+ *
+ * /&#42; starting CSS styles &#42;/
+ * opacity:1;
+ * }
+ * .fade-add.fade-add-active {
+ * /&#42; this will be the length of the animation &#42;/
+ * transition:1s linear all;
+ * opacity:0;
+ * }
+ * ```
+ *
+ * The setup CSS class (in this case `.fade-add`) also has a transition style property, however, it
+ * has a duration of zero. This may not be required, however, incase the browser is unable to render
+ * the styling present in this CSS class instantly then it could be that the browser is attempting
+ * to perform an unnecessary transition.
+ *
+ * This workaround, however, does not apply to standard class-based transitions that are rendered
+ * when a CSS class containing a transition is applied to an element:
+ *
+ * ```css
+ * /&#42; this works as expected &#42;/
+ * .fade {
+ * transition:1s linear all;
+ * opacity:0;
+ * }
+ * ```
+ *
+ * Please keep this in mind when coding the CSS markup that will be used within class-based transitions.
+ * Also, try not to mix the two class-based animation flavors together since the CSS code may become
+ * overly complex.
+ *
+ *
+ * ### Preventing Collisions With Third Party Libraries
+ *
+ * Some third-party frameworks place animation duration defaults across many element or className
+ * selectors in order to make their code small and reuseable. This can lead to issues with ngAnimate, which
+ * is expecting actual animations on these elements and has to wait for their completion.
+ *
+ * You can prevent this unwanted behavior by using a prefix on all your animation classes:
+ *
+ * ```css
+ * /&#42; prefixed with animate- &#42;/
+ * .animate-fade-add.animate-fade-add-active {
+ * transition:1s linear all;
+ * opacity:0;
+ * }
+ * ```
+ *
+ * You then configure `$animate` to enforce this prefix:
+ *
+ * ```js
+ * $animateProvider.classNameFilter(/animate-/);
+ * ```
+ * </div>
+ *
+ * ### 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 {
+ * /&#42; standard transition code &#42;/
+ * -webkit-transition: 1s linear all;
+ * transition: 1s linear all;
+ * opacity:0;
+ * }
+ * .my-animation.ng-enter-stagger {
+ * /&#42; this will have a 100ms delay between each successive leave animation &#42;/
+ * -webkit-transition-delay: 0.1s;
+ * transition-delay: 0.1s;
+ *
+ * /&#42; in case the stagger doesn't work then these two values
+ * must be set to 0 to avoid an accidental CSS inheritance &#42;/
+ * -webkit-transition-duration: 0s;
+ * transition-duration: 0s;
+ * }
+ * .my-animation.ng-enter.ng-enter-active {
+ * /&#42; standard transition styles &#42;/
+ * 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 more than 10ms has passed after the last animation has been 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
+ *
+ * $timeout(function() {
+ * //stagger has reset itself
+ * $animate.leave(kids[5]); //stagger index=0
+ * $animate.leave(kids[6]); //stagger index=1
+ * }, 100, false);
+ * ```
+ *
+ * Stagger animations are currently only supported within CSS-defined animations.
+ *
+ * ## JavaScript-defined Animations
+ * In the event that you do not want to use CSS3 transitions or CSS3 animations or if you wish to offer animations on browsers that do not
+ * yet support CSS transitions/animations, then you can make use of JavaScript animations defined inside of your AngularJS module.
+ *
+ * ```js
+ * //!annotate="YourApp" Your AngularJS Module|Replace this or ngModule with the module that you used to define your application.
+ * var ngModule = angular.module('YourApp', ['ngAnimate']);
+ * ngModule.animation('.my-crazy-animation', function() {
+ * return {
+ * enter: function(element, done) {
+ * //run the animation here and call done when the animation is complete
+ * return function(cancelled) {
+ * //this (optional) function will be called when the animation
+ * //completes or when the animation is cancelled (the cancelled
+ * //flag will be set to true if cancelled).
+ * };
+ * },
+ * leave: function(element, done) { },
+ * move: function(element, done) { },
+ *
+ * //animation that can be triggered before the class is added
+ * beforeAddClass: function(element, className, done) { },
+ *
+ * //animation that can be triggered after the class is added
+ * addClass: function(element, className, done) { },
+ *
+ * //animation that can be triggered before the class is removed
+ * beforeRemoveClass: function(element, className, done) { },
+ *
+ * //animation that can be triggered after the class is removed
+ * removeClass: function(element, className, done) { }
+ * };
+ * });
+ * ```
+ *
+ * JavaScript-defined animations are created with a CSS-like class selector and a collection of events which are set to run
+ * a javascript callback function. When an animation is triggered, $animate will look for a matching animation which fits
+ * the element's CSS class attribute value and then run the matching animation event function (if found).
+ * In other words, if the CSS classes present on the animated element match any of the JavaScript animations then the callback function will
+ * be executed. It should be also noted that only simple, single class selectors are allowed (compound class selectors are not supported).
+ *
+ * Within a JavaScript animation, an object containing various event callback animation functions is expected to be returned.
+ * As explained above, these callbacks are triggered based on the animation event. Therefore if an enter animation is run,
+ * and the JavaScript animation is found, then the enter callback will handle that animation (in addition to the CSS keyframe animation
+ * or transition code that is defined via a stylesheet).
+ *
+ *
+ * ### Applying Directive-specific Styles to an Animation
+ * In some cases a directive or service may want to provide `$animate` with extra details that the animation will
+ * include into its animation. Let's say for example we wanted to render an animation that animates an element
+ * towards the mouse coordinates as to where the user clicked last. By collecting the X/Y coordinates of the click
+ * (via the event parameter) we can set the `top` and `left` styles into an object and pass that into our function
+ * call to `$animate.addClass`.
+ *
+ * ```js
+ * canvas.on('click', function(e) {
+ * $animate.addClass(element, 'on', {
+ * to: {
+ * left : e.client.x + 'px',
+ * top : e.client.y + 'px'
+ * }
+ * }):
+ * });
+ * ```
+ *
+ * Now when the animation runs, and a transition or keyframe animation is picked up, then the animation itself will
+ * also include and transition the styling of the `left` and `top` properties into its running animation. If we want
+ * to provide some starting animation values then we can do so by placing the starting animations styles into an object
+ * called `from` in the same object as the `to` animations.
+ *
+ * ```js
+ * canvas.on('click', function(e) {
+ * $animate.addClass(element, 'on', {
+ * from: {
+ * position: 'absolute',
+ * left: '0px',
+ * top: '0px'
+ * },
+ * to: {
+ * left : e.client.x + 'px',
+ * top : e.client.y + 'px'
+ * }
+ * }):
+ * });
+ * ```
+ *
+ * Once the animation is complete or cancelled then the union of both the before and after styles are applied to the
+ * element. If `ngAnimate` is not present then the styles will be applied immediately.
+ *

+ * @ngdoc service
+ * @name $animate
+ * @kind object
+ *
+ * @description
+ * The `$animate` service provides animation detection support while performing DOM operations (enter, leave and move) as well as during addClass and removeClass operations.
+ * When any of these operations are run, the $animate service
+ * will examine any JavaScript-defined animations (which are defined by using the $animateProvider provider object)
+ * as well as any CSS-defined animations against the CSS classes present on the element once the DOM operation is run.
+ *
+ * The `$animate` service is used behind the scenes with pre-existing directives and animation with these directives
+ * will work out of the box without any extra configuration.
+ *
+ * Requires the {@link ngAnimate `ngAnimate`} module to be installed.
+ *
+ * Please visit the {@link ngAnimate `ngAnimate`} module overview page learn more about how to use animations in your application.
+ * ## Callback Promises
+ * With AngularJS 1.3, each of the animation methods, on the `$animate` service, return a promise when called. The
+ * promise itself is then resolved once the animation has completed itself, has been cancelled or has been
+ * skipped due to animations being disabled. (Note that even if the animation is cancelled it will still
+ * call the resolve function of the animation.)
+ *
+ * ```js
+ * $animate.enter(element, container).then(function() {
+ * //...this is called once the animation is complete...
+ * });
+ * ```
+ *
+ * Also note that, due to the nature of the callback promise, if any Angular-specific code (like changing the scope,
+ * location of the page, etc...) is executed within the callback promise then be sure to wrap the code using
+ * `$scope.$apply(...)`;
+ *
+ * ```js
+ * $animate.leave(element).then(function() {
+ * $scope.$apply(function() {
+ * $location.path('/new-page');
+ * });
+ * });
+ * ```
+ *
+ * An animation can also be cancelled by calling the `$animate.cancel(promise)` method with the provided
+ * promise that was returned when the animation was started.
+ *
+ * ```js
+ * var promise = $animate.addClass(element, 'super-long-animation');
+ * promise.then(function() {
+ * //this will still be called even if cancelled
+ * });
+ *
+ * element.on('click', function() {
+ * //tooo lazy to wait for the animation to end
+ * $animate.cancel(promise);
+ * });
+ * ```
+ *
+ * (Keep in mind that the promise cancellation is unique to `$animate` since promises in
+ * general cannot be cancelled.)
