| /** |
| * This interface is the root of listener interfaces that |
| * handle <tt>NamingEvent</tt>s. |
| * It does not make sense for a listener to implement just this interface. |
| * A listener typically implements a subinterface of <tt>NamingListener</tt>, |
| * such as <tt>ObjectChangeListener</tt> or <tt>NamespaceChangeListener</tt>. |
| *<p> |
| * This interface contains a single method, <tt>namingExceptionThrown()</tt>, |
| * that must be implemented so that the listener can be notified of |
| * exceptions that are thrown (by the service provider) while gathering |
| * information about the events that they're interested in. |
| * When this method is invoked, the listener has been automatically deregistered |
| * from the <tt>EventContext</tt> with which it has registered. |
| *<p> |
| * For example, suppose a listener implements <tt>ObjectChangeListener</tt> and |
| * registers with a <tt>EventContext</tt>. |
| * Then, if the connection to the server is subsequently broken, |
| * the listener will receive a <tt>NamingExceptionEvent</tt> and may |
| * take some corrective action, such as notifying the user of the application. |
