public class JboEvent

extends java.util.EventObject

The superclass of events in the Business Components for Java framework.

The Business Components framework follows the standard Java/EJB event delegation model for propagating events among middle-tier objects. Publishers (also called senders) generate events, subscribers (also called listeners) respond to them. The framework sends an event from a publisher to a subscriber by passing an event instance to a subscriber method.

The publisher defines the set of events it generates, and associates them with listeners by providing addEventTypeListener methods.

Subscribers implement java.util.EventListener.
