Interface ObjectChangeListener

All Superinterfaces:
EventListener, NamingListener

public interface ObjectChangeListener
extends NamingListener

Specifies the method that a listener of a NamingEvent with event type of OBJECT_CHANGED must implement.

An OBJECT_CHANGED event type is fired when (the contents of) an object has changed. This might mean that its attributes have been modified, added, or removed, and/or that the object itself has been replaced. How the object has changed can be determined by examining the NamingEvent's old and new bindings.

A listener interested in OBJECT_CHANGED event types must:

  1. Implement this interface and its method (objectChanged())
  2. Implement NamingListener.namingExceptionThrown() so that it will be notified of exceptions thrown while attempting to collect information about the events.
  3. Register with the source using the source's addNamingListener() method.
A listener that wants to be notified of namespace change events should also implement the NamespaceChangeListener interface.
