All Implemented Interfaces:

java.util.EventListener, IMListener, java.io.Serializable

public abstract class IMAdapter

extends java.lang.Object

implements IMListener, java.io.Serializable

An abstract adapter class receiving instant messaging events.

The class that is interested in processing an instant messaging event either extends this class (overriding only the methods of interest) or implements the IMListener interface (and all the methods it contains).

The listener object created from that class is then registered with the instant messaging framework using the ProtocolManager.setIMListener(IMListener) method.
