/**
  * This interface is the root of listener interfaces that
  * handle <tt>NamingEvents.
  * It does not make sense for a listener to implement just this interface.
  * A listener typically implements a subinterface of <tt>NamingListener,
  * such as <tt>ObjectChangeListener or NamespaceChangeListener.
  *<p>
  * This interface contains a single method, <tt>namingExceptionThrown(),
  * 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 with which it has registered.
  *<p>
  * For example, suppose a listener implements <tt>ObjectChangeListener and
  * registers with a <tt>EventContext.
  * Then, if the connection to the server is subsequently broken,
  * the listener will receive a <tt>NamingExceptionEvent and may
  * take some corrective action, such as notifying the user of the application.
