public abstract class MovingBodyAdapter
extends Object
implements MovingBody

Normal users can ignore this class. A class that implements many of the methods of MovingBody by delegating the work to Shape objects. This class is only made available for those wishing to create new type of MovingBody classes. Created: Sat Jan 31 14:56:17 2004
