This interface is for handling
UnsolicitedNotificationEvent.
"Unsolicited notification" is defined in
RFC 2251.
It allows the server to send unsolicited notifications to the client.
A
UnsolicitedNotificationListener must:
- Implement this interface and its method
- Implement NamingListener.namingExceptionThrown() so
that it will be notified of exceptions thrown while attempting to
collect unsolicited notification events.
- Register with the context using one of the addNamingListener()
methods from EventContext or EventDirContext.
Only the NamingListener argument of these methods are applicable;
the rest are ignored for a UnsolicitedNotificationListener.
(These arguments might be applicable to the listener if it implements
other listener interfaces).
