Class InterpolatingAnimation

  • Direct Known Subclasses:
    MotionAnimation, SimpleAnimation

    public abstract class InterpolatingAnimation
    extends AbstractAnimation
    An abstract animation class for those animations that interpolate values. Specifically, this is for animations that have the 'calcMode', 'keyTimes', 'keySplines', 'additive' and 'cumulative' attributes.

    • Field Detail

      • calcMode

        protected int calcMode
        The interpolation mode of this animator. This should take one of the CALC_MODE_* constants defined in AbstractAnimation.
      • keyTimes

        protected float[] keyTimes
        Time values to control the pacing of the animation.
      • keySplines

        protected float[] keySplines
        Bezier control points that control the pacing of the animation.
      • keySplineCubics

        protected Cubic[] keySplineCubics
        Cubics built from the bezier control points in keySplines.
      • additive

        protected boolean additive
        Whether this animation adds to ones below it in the animation sandwich or replaces them.
      • cumulative

        protected boolean cumulative
        Whether this animation accumulates from previous iterations.

      • InterpolatingAnimation

        public InterpolatingAnimation​(TimedElement timedElement,
                                      AnimatableElement animatableElement,

                                      float[] keySplines,
                                      boolean additive,
                                      boolean cumulative)
        Creates a new InterpolatingAnimation.
    • Method Detail

      • willReplace

        protected boolean willReplace()
        Returns whether this animation will replace values on animations lower in the sandwich.
        Overrides:
        willReplace in class AbstractAnimation
      • sampledLastValue

        protected void sampledLastValue​(int repeatIteration)
        Called when the element is sampled for its "last" value.
        Overrides:
        sampledLastValue in class AbstractAnimation
      • sampledAt

        protected void sampledAt​(float simpleTime,
                                 float simpleDur,
                                 int repeatIteration)
        Called when the element is sampled at the given time.
        Specified by:
        sampledAt in class AbstractAnimation
      • sampledAtUnitTime

        protected abstract void sampledAtUnitTime​(float unitTime,
                                                  int repeatIteration)
        Called when the element is sampled at the given unit time. This updates the AbstractAnimation.value of the animation if active.
