## Interface UnsolicitedNotificationListener

- All Superinterfaces:
    EventListener, NamingListener

      public interface UnsolicitedNotificationListener
      extends NamingListener

  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:
  1. Implement this interface and its method
  2. Implement `NamingListener.namingExceptionThrown()` so that it will be notified of exceptions thrown while attempting to collect unsolicited notification events.
  3. 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).
  Since:
    1.3
