• AnimationScheduler

  public AnimationScheduler()

Method Detail

• get

  public static AnimationScheduler get()

  Returns the default implementation of the AnimationScheduler API.

• requestAnimationFrame

  public AnimationScheduler.AnimationHandle requestAnimationFrame(AnimationScheduler.AnimationCallback callback)

  Schedule an animation, letting the browser decide when to trigger the next step in the animation.

  NOTE: If you are animating an element, use requestAnimationFrame(AnimationCallback, Element) instead so the browser can optimize for the specified element.

  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.

  Parameters:

  callback - the callback to fire

  Returns:

  a handle to the requested animation frame
