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 Summary

Fields

Modifier and Type	Field	Description
protected boolean	additive	Whether this animation adds to ones below it in the animation sandwich or replaces them.
protected int	calcMode	The interpolation mode of this animator.
protected boolean	cumulative	Whether this animation accumulates from previous iterations.
protected Cubic[]	keySplineCubics	Cubics built from the bezier control points in keySplines.
protected float[]	keySplines	Bezier control points that control the pacing of the animation.
protected float[]	keyTimes	Time values to control the pacing of the animation.

Field Details

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.

Constructor Details

InterpolatingAnimation

public InterpolatingAnimation(TimedElement timedElement,
 AnimatableElement animatableElement,
 int calcMode,
 float[] keyTimes,
 float[] keySplines,
 boolean additive,
 boolean cumulative)

Creates a new InterpolatingAnimation.

Method Details

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.
