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.
