      • time

        protected java.util.Calendar time
        Calendar instance used for passing current time values to the animation timing system.
      • waitTime

        protected long waitTime
        The number of milliseconds to wait until the next animation tick. This is returned by getWaitTime().
      • times

        protected long[] times
        The past tick times.
      • sumTime

        protected long sumTime
        The sum of the times in times.
      • timeIndex

        protected int timeIndex
        The current index into times.
      • engRef

        protected java.lang.ref.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.
      • MAX_EXCEPTION_COUNT

        protected static final int MAX_EXCEPTION_COUNT
        The maximum number of consecutive exceptions to allow before stopping the report of them.

      • 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.
    • Method Detail

      • resume

        public void resume()
        Forces an animation update, if the RunnableQueue is currently waiting.
      • getWaitTime

        public long getWaitTime()
        Returns the system time that can be safely waited until before this Runnable is run again.
