/**
* Contains methods for registering listeners to be notified
* of events fired when objects named in a directory context changes.
*<p>
* The methods in this interface support identification of objects by
* <A HREF="ftp://ftp.isi.edu/in-notes/rfc2254.txt">RFC 2254</a>
* search filters.
*
*<P>Using the search filter, it is possible to register interest in objects
* that do not exist at the time of registration but later come into existence and
* satisfy the filter. However, there might be limitations in the extent
* to which this can be supported by the service provider and underlying
* protocol/service. If the caller submits a filter that cannot be
* supported in this way, <tt>addNamingListener()</tt> throws an
* <tt>InvalidSearchFilterException</tt>.
*<p>
* See <tt>EventContext</tt> for a description of event source
* and target, and information about listener registration/deregistration
* that are also applicable to methods in this interface.
* See the
* <a href=package-summary.html#THREADING>package description</a>
* for information on threading issues.
*<p>
* A <tt>SearchControls</tt> or array object
* passed as a parameter to any method is owned by the caller.
* The service provider will not modify the object or keep a reference to it.
