          com.google.gwt.animation.client.testing.StubAnimationScheduler

    public class StubAnimationScheduler

extends AnimationScheduler

A stub implementation of `AnimationScheduler` that does not execute the callbacks. Use `getAnimationCallbacks()` to retrieve and execute callbacks manually.

Nested Class Summary
`class` | `StubAnimationScheduler.StubAnimationHandle` A handle to the requested animation frame created by `AnimationScheduler.requestAnimationFrame(AnimationCallback, Element)`.

Constructor Summary
`StubAnimationScheduler()`

Method Summary
`java.util.List<AnimationScheduler.AnimationCallback>` | `getAnimationCallbacks()` Get the list of all animation callbacks that have been requested and have not been canceled.
`StubAnimationScheduler.StubAnimationHandle` | `requestAnimationFrame(AnimationScheduler.AnimationCallback callback, Element element)` Schedule an animation, letting the browser decide when to trigger the next step in the animation.

Constructor Detail

### StubAnimationScheduler

    public StubAnimationScheduler()

Method Detail

### getAnimationCallbacks

    public java.util.List<AnimationScheduler.AnimationCallback> getAnimationCallbacks()

  Get the list of all animation callbacks that have been requested and have not been canceled.

  Returns:
    the list of callbacks.

### requestAnimationFrame

    public StubAnimationScheduler.StubAnimationHandle requestAnimationFrame(AnimationScheduler.AnimationCallback callback,
                                                                            Element element)

  Description copied from class: `AnimationScheduler`
  Schedule an animation, letting the browser decide when to trigger the next step in the animation.

  Using this method instead of a timeout is preferred because the browser is in the best position to decide how frequently to trigger the callback for an animation of the specified element. The browser can balance multiple animations and trigger callbacks at the optimal rate for smooth performance.

  Specified by:
    `requestAnimationFrame` in class `AnimationScheduler`
  Parameters:
    `callback` - the callback to fire
    `element` - the element being animated
  Returns:
    a handle to the requested animation frame
