Field Detail

engRef

protected WeakReference engRef

A weak reference to the SVGAnimationEngine this AnimationTickRunnable is for. We make this a WeakReference so that a ticking animation engine does not prevent from being GCed.

exceptionCount

protected int exceptionCount

The number of consecutive exceptions that have been thrown. This is used to detect when exceptions are occurring every tick, and to stop reporting them when this happens.
