Constructor Detail

• Animation

  public Animation()

  Construct a new Animation.

• Animation

  protected Animation(AnimationScheduler scheduler)

  Construct a new AnimationScheduler using the specified scheduler to sheduler request frames.

  Parameters:

  scheduler - an AnimationScheduler instance

Method Detail

• cancel

  public void cancel()

  Immediately cancel this animation. If the animation is running or is scheduled to run, onCancel() will be called.

• run

  public void run(int duration)

  Immediately run this animation. If the animation is already running, it will be canceled first.

  This is equivalent to run(duration, null).

  Parameters:

  duration - the duration of the animation in milliseconds

  See Also:

  run(int, Element)

• run

  public void run(int duration,
         Element element)

  Immediately run this animation. If the animation is already running, it will be canceled first.

  If the element is not null, the onUpdate(double) method might be called only if the element may be visible (generally left at the appreciation of the browser). Otherwise, it will be called unconditionally.

  Parameters:

  duration - the duration of the animation in milliseconds

  element - the element that visually bounds the entire animation

• run

  public void run(int duration,
         double startTime)

  Run this animation at the given startTime. If the startTime has already passed, the animation will run synchronously as if it started at the specified start time. If the animation is already running, it will be canceled first.

  This is equivalent to run(duration, startTime, null).

  Parameters:

  duration - the duration of the animation in milliseconds

  startTime - the synchronized start time in milliseconds

  See Also:

  run(int, double, Element)

• run

  public void run(int duration,
         double startTime,
         Element element)

  Run this animation at the given startTime. If the startTime has already passed, the animation will run synchronously as if it started at the specified start time. If the animation is already running, it will be canceled first.

  If the element is not null, the onUpdate(double) method might be called only if the element may be visible (generally left at the appreciation of the browser). Otherwise, it will be called unconditionally.

  Parameters:

  duration - the duration of the animation in milliseconds

  startTime - the synchronized start time in milliseconds

  element - the element that visually bounds the entire animation

• isRunning

  public boolean isRunning()

  Returns true if the animation is running. Note that animation may be 'running' but no callbacks is executed yet.

• interpolate

  protected double interpolate(double progress)

  Interpolate the linear progress into a more natural easing function. Depending on the Animation, the return value of this method can be less than 0.0 or greater than 1.0.

  Parameters:

  progress - the linear progress, between 0.0 and 1.0

  Returns:

  the interpolated progress

• onCancel

  protected void onCancel()

  Called immediately after the animation is canceled. The default implementation of this method calls onComplete() only if the animation has actually started running.

• onComplete

  protected void onComplete()

  Called immediately after the animation completes.

• onStart

  protected void onStart()

  Called immediately before the animation starts.

• onUpdate

  protected abstract void onUpdate(double progress)

  Called when the animation should be updated. The value of progress is between 0.0 and 1.0 (inclusive) (unless you override the interpolate(double) method to provide a wider range of values). There is no guarantee that onUpdate(double) is called with 0.0 or 1.0. If you need to perform setup or tear down procedures, you can override onStart() and onComplete().

  Parameters:

  progress - a double, normally between 0.0 and 1.0 (inclusive)
