31 * This interface is for handling <tt>UnsolicitedNotificationEvent</tt>.
32 * "Unsolicited notification" is defined in
33 * <A HREF="ftp://ftp.isi.edu/in-notes/rfc2251.txt">RFC 2251</A>.
34 * It allows the server to send unsolicited notifications to the client.
35 * A <tt>UnsolicitedNotificationListener</tt> must:
36 *<ol>
37 * <li>Implement this interface and its method
38 * <li>Implement <tt>NamingListener.namingExceptionThrown()</tt> so
39 * that it will be notified of exceptions thrown while attempting to
40 * collect unsolicited notification events.
41 * <li>Register with the context using one of the <tt>addNamingListener()</tt>
42 * methods from <tt>EventContext</tt> or <tt>EventDirContext</tt>.
43 * Only the <tt>NamingListener</tt> argument of these methods are applicable;
44 * the rest are ignored for a <tt>UnsolicitedNotificationListener</tt>.
45 * (These arguments might be applicable to the listener if it implements
46 * other listener interfaces).
