Interface NamespaceChangeListener
- All Superinterfaces:
-
EventListener
,NamingListener
public interface NamespaceChangeListener extends NamingListener
Specifies the methods that a listener interested in namespace changes must implement. Specifically, the listener is interested in NamingEvent
s with event types of OBJECT_ADDED, OBJECT_RENAMED
, or OBJECT_REMOVED
.
Such a listener must:
- Implement this interface and its methods.
- Implement
NamingListener.namingExceptionThrown()
so that it will be notified of exceptions thrown while attempting to collect information about the events. - Register with the source using the source's
addNamingListener()
method.
OBJECT_CHANGED
event types should also implement the ObjectChangeListener
interface.- Since:
- 1.3
