# Class Animation

java.lang.Object
javafx.animation.Animation

Direct Known Subclasses:
  `Timeline`, `Transition`

public abstract class Animation extends Object
The class `Animation` provides the core functionality of all animations used in the JavaFX runtime.

An animation can run in a loop by setting `cycleCount`. To make an animation run back and forth while looping, set the `autoReverse` -flag.

Call `play()` or `playFromStart()` to play an `Animation` . The `Animation` progresses in the direction and speed specified by `rate`, and stops when its duration is elapsed. An `Animation` with indefinite duration (a `cycleCount` of `INDEFINITE`) runs repeatedly until the `stop()` method is explicitly called, which will stop the running `Animation` and reset its play head to the initial position.

An `Animation` can be paused by calling `pause()`, and the next `play()` call will resume the `Animation` from where it was paused.

An `Animation`'s play head can be randomly positioned, whether it is running or not. If the `Animation` is running, the play head jumps to the specified position immediately and continues playing from new position. If the `Animation` is not running, the next `play()` will start the `Animation` from the specified position.

Inverting the value of `rate` toggles the play direction.

The animation runs on the JavaFX Application Thread.

  JavaFX 2.0

- ## Property Details

  - ### rate

    public final DoubleProperty rateProperty
    Defines the direction/speed at which the `Animation` is expected to be played.

    The absolute value of `rate` indicates the speed at which the `Animation` is to be played, while the sign of `rate` indicates the direction. A positive value of `rate` indicates forward play, a negative value indicates backward play and `0.0` to stop a running `Animation`.

    Rate `1.0` is normal play, `2.0` is 2 time normal, `-1.0` is backwards, etc.

    Inverting the rate of a running `Animation` will cause the `Animation` to reverse direction in place and play back over the portion of the `Animation` that has already elapsed.

    Default value:
      1.0
    See Also:
      - `getRate()`
      - `setRate(double)`
      - `rateProperty()`

  - ### currentRate

    public final ReadOnlyDoubleProperty currentRateProperty
    Read-only variable to indicate current direction/speed at which the `Animation` is being played.

    `currentRate` is not necessarily equal to `rate`. `currentRate` is set to `0.0` when animation is paused or stopped. `currentRate` may also point in the opposite direction of `rate` during reverse cycles when `autoReverse` is `true`.

    Default value:
      0.0

    Returns:
      the `status` property
    See Also:
      - `getStatus()`
      - `setStatus(Animation.Status)`

    Default value:
      null
    Returns:
      the `onFinished` property
    See Also:
      - `getOnFinished()`
      - `setOnFinished(EventHandler)`

  - ### getCuePoints

    public final ObservableMap<String,Duration> getCuePoints()
    The cue points can be used to mark important positions of the `Animation`. Once a cue point was defined, it can be used as an argument of `jumpTo()` and `playFrom()` to move to the associated position quickly.

    Every `Animation` has two predefined cue points `"start"` and `"end"`, which are set at the start respectively the end of the `Animation`. The predefined cuepoints do not appear in the map, attempts to override them have no effect.

    Another option to define a cue point in a `Animation` is to set the `name` property of a `KeyFrame`.

    Returns:
      `ObservableMap` of cue points

  - ### jumpTo

    public void jumpTo(Duration time)
    Jumps to a given position in this `Animation`. If the given time is less than `Duration.ZERO`, this method will jump to the start of the animation. If the given time is larger than the duration of this `Animation`, this method will jump to the end.
    Parameters:
      `time` - the new position
    Throws:
      `NullPointerException` - if `time` is `null`
      `IllegalArgumentException` - if `time` is `Duration.UNKNOWN`
      `IllegalStateException` - if embedded in another animation, such as `SequentialTransition` or `ParallelTransition`

  - ### jumpTo

    public void jumpTo(String cuePoint)
    Jumps to a predefined position in this `Animation`. This method looks for an entry in cue points and jumps to the associated position, if it finds one.

    If the cue point is behind the end of this `Animation`, calling `jumpTo` will result in a jump to the end. If the cue point has a negative `Duration` it will result in a jump to the beginning. If the cue point has a value of `Duration.UNKNOWN` calling `jumpTo` will have no effect for this cue point.

    There are two predefined cue points `"start"` and `"end"` which are defined to be at the start respectively the end of this `Animation`.

    Parameters:
      `cuePoint` - the name of the cue point
    Throws:
      `NullPointerException` - if `cuePoint` is `null`
      `IllegalStateException` - if embedded in another animation, such as `SequentialTransition` or `ParallelTransition`
    See Also:
      - `getCuePoints()`

  - ### playFrom

    public void playFrom(String cuePoint)
    A convenience method to play this `Animation` from a predefined position. The position has to be predefined in cue points. Calling this method is equivalent to

         animation.jumpTo(cuePoint);
         animation.play();

    Note that unlike `playFromStart()` calling this method will not change the playing direction of this `Animation`.

    Note: if this method is not called on the JavaFX Application Thread, it is delegated to it automatically. In this case, the call is asynchronous and may not happen immediately.

    Parameters:
      `cuePoint` - name of the cue point
    Throws:
      `NullPointerException` - if `cuePoint` is `null`
      `IllegalStateException` - if embedded in another animation, such as `SequentialTransition` or `ParallelTransition`
    See Also:
      - `getCuePoints()`

  - ### playFrom

    public void playFrom(Duration time)
    A convenience method to play this `Animation` from a specific position. Calling this method is equivalent to

         animation.jumpTo(time);
         animation.play();

    Note that unlike `playFromStart()` calling this method will not change the playing direction of this `Animation`.

    Note: if this method is not called on the JavaFX Application Thread, it is delegated to it automatically. In this case, the call is asynchronous and may not happen immediately.

    Parameters:
      `time` - position where to play from
    Throws:
      `NullPointerException` - if `time` is `null`
      `IllegalArgumentException` - if `time` is `Duration.UNKNOWN`
      `IllegalStateException` - if embedded in another animation, such as `SequentialTransition` or `ParallelTransition`

  - ### playFromStart

    public void playFromStart()
    Plays an `Animation` from initial position in forward direction.

    It is equivalent to

    `animation.stop();
    animation.setRate = setRate(Math.abs(animation.getRate()));
    animation.jumpTo(Duration.ZERO);
    animation.play();
    `

    Note: if this method is not called on the JavaFX Application Thread, it is delegated to it automatically. In this case, the call is asynchronous and may not happen immediately.

    Throws:
      `IllegalStateException` - if embedded in another animation, such as `SequentialTransition` or `ParallelTransition`

  - ### play

    public void play()
    Plays `Animation` from current position in the direction indicated by `rate`. If the `Animation` is running, it has no effect.

    When `rate` > 0 (forward play), if an `Animation` is already positioned at the end, the first cycle will not be played, it is considered to have already finished. This also applies to a backward ( `rate` < 0) cycle if an `Animation` is positioned at the beginning. However, if the `Animation` has `cycleCount` > 1, following cycle(s) will be played as usual.

    When the `Animation` reaches the end, the `Animation` is stopped and the play head remains at the end.

    To play an `Animation` backwards from the end:
    `animation.setRate(negative rate);
    animation.jumpTo(overall duration of animation);
    animation.play();
    `

    Note: if this method is not called on the JavaFX Application Thread, it is delegated to it automatically. In this case, the call is asynchronous and may not happen immediately.

    Throws:
      `IllegalStateException` - if embedded in another animation, such as `SequentialTransition` or `ParallelTransition`

  - ### stop

    public void stop()
    Stops the animation and resets the play head to its initial position. If the animation is already stopped, this method has no effect.

    Note: if this method is not called on the JavaFX Application Thread, it is delegated to it automatically. In this case, the call is asynchronous and may not happen immediately.

    Throws:
      `IllegalStateException` - if embedded in another animation, such as `SequentialTransition` or `ParallelTransition`

  - ### pause

    public void pause()
    Pauses the animation. If the animation is not currently running, this method has no effect.

    Note: if this method is not called on the JavaFX Application Thread, it is delegated to it automatically. In this case, the call is asynchronous and may not happen immediately.

    Throws:
      `IllegalStateException` - if embedded in another animation, such as `SequentialTransition` or `ParallelTransition`

  - ### getTargetFramerate

    public final double getTargetFramerate()
    The target framerate is the maximum framerate at which this `Animation` will run, in frames per second. This can be used, for example, to keep particularly complex `Animations` from over-consuming system resources. By default, an `Animation`'s framerate is not explicitly limited, meaning the `Animation` will run at an optimal framerate for the underlying platform.
    Returns:
      the target framerate
