Method Detail

requestAnimationFrame

public AnimationScheduler.AnimationHandle 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

isNativelySupported

protected boolean isNativelySupported()

Description copied from class: AnimationSchedulerImpl

Check if the implementation is natively supported.

Specified by:: isNativelySupported in class AnimationSchedulerImpl

Returns:: true if natively supported, false if not
