javax.naming.event

public Interface NamespaceChangeListener

extends NamingListener
Specifies the methods that a listener interested in namespace changes must implement. Specifically, the listener is interested in NamingEvents with event types of OBJECT_ADDED, OBJECT_RENAMED, or OBJECT_REMOVED.

Such a listener must:

  1. Implement this interface and its methods.
  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 OBJECT_CHANGED event types should also implement the ObjectChangeListener interface.
