public class Event
extends EventObject
implements Cloneable

Base class for events. Events have a type and a source. The source is the instance that raised the event. There are different event types for a given event. The types are represented in a hierarchical structure. Events can be chained, which means a event listener can catch events and rethrow them as its own event.
