java.lang.Object
   |
   +----improv.event.ImprovObservable
public abstract class ImprovObservable
extends Object
This class is the superclass of all Improv Objects which generate events It is more flexible than the standard Observable class provided in Java. Because it allows each observer to register an object which will be passed back to the observer when an ImprovEvent is generated. An observer may also register itself more than once, providing multiple object arguments.
