* `animate` is an animation-specific function that is designed to be used inside of Angular2's animation
* DSL language. If this information is new, please navigate to the
* {@link ComponentMetadata#animations-anchor component animations metadata
* page} to gain a better understanding of how animations in Angular2 are used.
*
* `animate` specifies an animation step that will apply the provided `styles` data for a given amount of
* time based on the provided `timing` expression value. Calls to `animate` are expected to be
* used within {@link sequence an animation sequence}, {@link group group}, or {@link transition transition}.
*
* ### Usage
*
* The `animate` function accepts two input parameters: `timing` and `styles`:
*
* - `timing` is a string based value that can be a combination of a duration with optional
* delay and easing values. The format for the expression breaks down to `duration delay easing`
* (therefore a value such as `1s 100ms ease-out` will be parse itself into `duration=1000, delay=100, easing=ease-out`.
* If a numeric value is provided then that will be used as the `duration` value in millisecond form.
* - `styles` is the style input data which can either be a call to {@link style style} or {@link keyframes keyframes}.
* If left empty then the styles from the destination state will be collected and used (this is useful when
* describing an animation step that will complete an animation by {@link transition#the-final-animate-call animating to the final state}).
*
* ```typescript
* // various functions for specifying timing data
* animate(500, style(...))
* animate("1s", style(...))
* animate("100ms 0.5s", style(...))
* animate("5s ease", style(...))
* animate("5s 10ms cubic-bezier(.17,.67,.88,.1)", style(...))
*
* // either style() of keyframes() can be used
* animate(500, style({ background: "red" }))
* animate(500, keyframes([
* style({ background: "blue" })),
* style({ background: "red" }))
* ])
* ```
*

* DSL language. If this information is new, please navigate to the
* {@link ComponentMetadata#animations-anchor component animations metadata
* page} to gain a better understanding of how animations in Angular2 are used.
*
* `group` specifies a list of animation steps that are all run in parallel. Grouped animations
* are useful when a series of styles must be animated/closed off
* at different statrting/ending times.
*
* The `group` function can either be used within a {@link sequence sequence} or a {@link transition transition}
* and it will only continue to the next instruction once all of the inner animation steps
* have completed.
*
* ### Usage
*
* The `steps` data that is passed into the `group` animation function can either consist
* of {@link style style} or {@link animate animate} function calls. Each call to `style()` or `animate()`
* within a group will be executed instantly (use {@link keyframes keyframes} or a
* {@link animate#usage animate() with a delay value} to offset styles to be applied at a later time).

*
* `sequence` Specifies a list of animation steps that are run one by one. (`sequence` is used
* by default when an array is passed as animation data into {@link transition transition}.)
*
* The `sequence` function can either be used within a {@link group group} or a {@link transition transition}
* and it will only continue to the next instruction once each of the inner animation steps

* of {@link style style} or {@link animate animate} function calls. A call to `style()` will apply the
* provided styling data immediately while a call to `animate()` will apply its styling
* data over a given time depending on its timing data.

*
* `style` declares a key/value object containing CSS properties/styles that can then
* be used for {@link state animation states}, within an {@link sequence animation sequence}, or as styling data for both {@link animate animate} and {@link keyframes keyframes}.
*
* ### Usage
*
* `style` takes in a key/value string map as data and expects one or more CSS property/value
* pairs to be defined.
*
* ```typescript
* // string values are used for css properties
* style({ background: "red", color: "blue" })
*
* // numerical (pixel) values are also supported
* style({ width: 100, height: 0 })
* ```
*
* #### Auto-styles (using `*`)
*
* When an asterix (`*`) character is used as a value then it will be detected from the element being animated
* and applied as animation data when the animation starts.
*
* This feature proves useful for a state depending on layout and/or environment factors; in such cases
* the styles are calculated just before the animation starts.
*
* ```typescript
* // the steps below will animate from 0 to the
* // actual height of the element
* style({ height: 0 }),
* animate("1s", style({ height: "*" }))
* ```

* DSL language. If this information is new, please navigate to the
* {@link ComponentMetadata#animations-anchor component animations metadata
* page} to gain a better understanding of how animations in Angular2 are used.
*
* `state` declares an animation state within the given trigger. When a state is
* active within a component then its associated styles will persist on
* the element that the trigger is attached to (even when the animation ends).
*
* To animate between states, have a look at the animation {@link transition transition}
* DSL function. To register states to an animation trigger please have a look
* at the {@link trigger trigger} function.
*
* #### The `void` state
*
* The `void` state value is a reserved word that angular uses to determine when the element is not apart
* of the application anymore (e.g. when an `ngIf` evaluates to false then the state of the associated element
* is void).
*
*
* ### Usage
*
* `state` will declare an animation state with its associated styles
* within the given trigger.
*
* - `stateNameExpr` can be one or more state names separated by commas.
* - `styles` refers to the {@link style styling data} that will be persisted on the element once the state
* has been reached.
*
* ```typescript
* // "void" is a reserved name for a state and is used to represent
* // the state in which an element is detached from from the application.
* state("void", style({ height: 0 }))
*
* // user-defined states
* state("closed", style({ height: 0 }))
* state("open, visible", style({ height: "*" }))
* ```

* DSL language. If this information is new, please navigate to the
* {@link ComponentMetadata#animations-anchor component animations metadata
* page} to gain a better understanding of how animations in Angular2 are used.
*
* `keyframes` specifies a collection of {@link style style} entries each optionally characterized by an `offset` value.
*
* ### Usage
*
* The `keyframes` animation function is designed to be used alongside the {@link animate animate}
* animation function. Instead of applying animations from where they are
* currently to their destination, keyframes can describe how each style entry is applied
* and at what point within the animation arc (much like CSS Keyframe Animations do).
*
* For each `style()` entry an `offset` value can be set. Doing so allows to specifiy at
* what percentage of the animate time the styles will be applied.
*
* ```typescript
* // the provided offset values describe when each backgroundColor value is applied.
* animate("5s", keyframes([
* style({ backgroundColor: "red", offset: 0 }),
* style({ backgroundColor: "blue", offset: 0.2 }),
* style({ backgroundColor: "orange", offset: 0.3 }),
* style({ backgroundColor: "black", offset: 1 })
* ]))
* ```
*
* Alternatively, if there are no `offset` values used within the style entries then the offsets will
* be calculated automatically.
*
* ```typescript
* animate("5s", keyframes([
* style({ backgroundColor: "red" }) // offset = 0
* style({ backgroundColor: "blue" }) // offset = 0.33
* style({ backgroundColor: "orange" }) // offset = 0.66
* style({ backgroundColor: "black" }) // offset = 1
* ]))
* ```

* DSL language. If this information is new, please navigate to the
* {@link ComponentMetadata#animations-anchor component animations metadata
* page} to gain a better understanding of how animations in Angular2 are used.
*
* `transition` declares the {@link sequence sequence of animation steps} that will be run when the provided
* `stateChangeExpr` value is satisfied. The `stateChangeExpr` consists of a `state1 => state2` which consists
* of two known states (use an asterix (`*`) to refer to a dynamic starting and/or ending state).
*
* Animation transitions are placed within an {@link trigger animation trigger}. For an transition to animate to
* a state value and persist its styles then one or more {@link state animation states} is expected to be defined.
*
* ### Usage
*
* An animation transition is kicked off the `stateChangeExpr` predicate evaluates to true based on what the
* previous state is and what the current state has become. In other words, if a transition is defined that
* matches the old/current state criteria then the associated animation will be triggered.
*
* ```typescript
* // all transition/state changes are defined within an animation trigger
* trigger("myAnimationTrigger", [
* // if a state is defined then its styles will be persisted when the
* // animation has fully completed itself
* state("on", style({ background: "green" })),
* state("off", style({ background: "grey" })),
*
* // a transition animation that will be kicked off when the state value
* // bound to "myAnimationTrigger" changes from "on" to "off"
* transition("on => off", animate(500)),
*
* // it is also possible to do run the same animation for both directions
* transition("on <=> off", animate(500)),
*
* // or to define multiple states pairs separated by commas
* transition("on => off, off => void", animate(500)),
*
* // this is a catch-all state change for when an element is inserted into
* // the page and the destination state is unknown
* transition("void => *", [
* style({ opacity: 0 }),
* animate(500)
* ]),
*
* // this will capture a state change between any states
* transition("* => *", animate("1s 0s")),
* ])
* ```
*
* The template associated with this component will make use of the `myAnimationTrigger`
* animation trigger by binding to an element within its template code.
*
* ```html
* <!-- somewhere inside of my-component-tpl.html -->
* <div @myAnimationTrigger="myStatusExp">...</div>
* ```
*
* #### The final `animate` call
*
* If the final step within the transition steps is a call to `animate()` that **only**
* uses a timing value with **no style data** then it will be automatically used as the final animation
* arc for the element to animate itself to the final state. This involves an automatic mix of
* adding/removing CSS styles so that the element will be in the exact state it should be for the
* applied state to be presented correctly.
*
* ```
* // start off by hiding the element, but make sure that it animates properly to whatever state
* // is currently active for "myAnimationTrigger"
* transition("void => *", [
* style({ opacity: 0 }),
* animate(500)
* ])
* ```

/**
* Animations are defined on components via an animation-like DSL. This DSL approach to describing
* animations allows for a flexibility that both benefits developers and the framework.
*
* Animations work by listening on state changes that occur on an element within
* the template. When a state change occurs, Angular can then take advantage and animate the
* arc in between. This works similar to how CSS transitions work, however, by having a
* programmatic DSL, animations are not limited to environments that are DOM-specific.
* (Angular can also perform optimizations behind the scenes to make animations more performant.)
*
* For animations to be available for use, animation state changes are placed within
* {@link trigger animation triggers} which are housed inside of the `animations` annotation
* metadata. Within a trigger both {@link state state} and {@link transition transition} entries
* can be placed.
*
* ```typescript
* @Component({
* selector: 'animation-cmp',
* templateUrl: 'animation-cmp.html',
* animations: [
* // this here is our animation trigger that
* // will contain our state change animations.
* trigger('myTriggerName', [
* // the styles defined for the `on` and `off`
* // states declared below are persisted on the
* // element once the animation completes.
* state('on', style({ opacity: 1 }),
* state('off', style({ opacity: 0 }),
*
* // this here is our animation that kicks off when
* // this state change jump is true
* transition('on => off', [
* animate("1s")
* ])
* ])
* ]
* })
* ```
*
* As depicted in the code above, a group of related animation states are all contained within
* an animation `trigger` (the code example above called the trigger `myTriggerName`).
* When a trigger is created then it can be bound onto an element within the component's
* template via a property prefixed by an `@` symbol followed by trigger name and an expression that
* is used to determine the state value for that trigger.
*
* ```html
* <!-- animation-cmp.html -->
* <div @myTriggerName="expression">...</div>
* ```
*
* For state changes to be executed, the `expression` value must change value from its existing value
* to something that we have set an animation to animate on (in the example above we are listening
* to a change of state between `on` and `off`). The `expression` value attached to the trigger
* must be something that can be evaluated with the template/component context.
*
* ### DSL Animation Functions
*
* Please visit each of the animation DSL functions listed below to gain a better understanding
* of how and why they are used for crafting animations in Angular2:
*
* - {@link trigger trigger()}
* - {@link state state()}
* - {@link transition transition()}
* - {@link group group()}
* - {@link sequence sequence()}
* - {@link style style()}
* - {@link animate animate()}
