All Implemented Interfaces:

java.lang.Runnable, Animator

public class AnimationImp
extends java.lang.Thread
implements Animator

This class implements the Animation front end for the JSIM Simulation package. It uses a shared data Structure to receive AnimatorMessages from the Simulator and then repaints the Animation to reflect these changes.
