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:
- Implement this interface and its method (objectChanged())
- 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.
A listener that wants to be notified of namespace change events
should also implement the NamespaceChangeListener
interface.

- 1.3
