+--edu.umd.cs.jazz.event.ZGroupAdapter
- All Implemented Interfaces:
- java.util.EventListener, java.io.Serializable, ZGroupListener
- public class ZGroupAdapter
- extends java.lang.Object
- implements ZGroupListener, java.io.Serializable
ZGroupAdapater is an abstract adapter class for receiving group events. The methods in this class are empty. This class exists as convenience for creating listener objects. Based on Swing's ComponentListener.
Extend this class to create a ZGroupEvent
listener and override the methods for the events of interest. (If you implement the ZGroupListener
interface, you have to define all of the methods in it. This abstract class defines null methods for them all, so you can only have to define methods for events you care about.)
Create a listener object using your class and then register it with a group using the group's addGroupListener
method. When the group's state changes, the relevant method in the listener object is invoked, and the ZGroupEvent
is passed to it.
Warning: Serialized and ZSerialized objects of this class will not be compatible with future Jazz releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Jazz. A future release of Jazz will provide support for long term persistence.
