public abstract class UserDataAdapter

extends Object

implements UserDataListener

An abstract adapter class for receiving user data events. The methods in this class are empty. This class exists as convenience for creating listener objects.

Extend this class to create a UserDataEvent listener and override the methods for the events of interest. (If you implement the UserDataListener interface, you have to define all of the methods in it. This abstract class defines empty method bodies for them all, so you can concentrate on defining methods only for events you care about.)

Create a listener object using the extended class and then register it with a UserManager using the UserManager's UserManager.addUserDataListener(users.events.UserDataListener) method. When a user is added or removed, the relevant method in the listener object is invoked, and the UserDataEvent is passed to it.
