I wouldn't say its elegant, but it does work for my purposes:
public class MallRotPosPathInterpolator extends RotPosPathInterpolator
{
public MallRotPosPathInterpolator(
Alpha alpha, TransformGroup target, Transform3D axisOfRotPos, float[]
knots,
Quat4f[] quats, Point3f[] positions)
{
super(alpha, target, axisOfRotPos, knots, quats, positions);
}
// Override to disable interpolator, if alpha has finished
public void processStimulus(Enumeration wakeupCriteria)
{
super.processStimulus(wakeupCriteria);
if(getAlpha().finished())
setEnable(false);
}
}
Hope this helps
