Interface EventDirContext
- All Superinterfaces:

Context

,EventContext
public interface EventDirContext extends EventContext, DirContext
Contains methods for registering listeners to be notified of events fired when objects named in a directory context changes.
The methods in this interface support identification of objects by RFC 2254 search filters.
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, addNamingListener()
throws an InvalidSearchFilterException
.
See EventContext
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 package description for information on threading issues.
A SearchControls
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.

Method Detail
addNamingListener
void addNamingListener(Name target, String filter, SearchControls ctls, NamingListener l) throws NamingException
Adds a listener for receiving naming events fired when objects identified by the search filter filter
at the object named by target are modified.
The scope, returningObj flag, and returningAttributes flag from the search controls ctls
are used to control the selection of objects that the listener is interested in, and determines what information is returned in the eventual NamingEvent
object. Note that the requested information to be returned might not be present in the NamingEvent
object if they are unavailable or could not be obtained by the service provider or service.
- Parameters:
-
target
- The nonnull name of the object resolved relative to this context. -
filter
- The nonnull string filter (see RFC2254). -
ctls
- The possibly null search controls. If null, the default search controls are used. -
l
- The nonnull listener. - Throws:
-
NamingException
- If a problem was encountered while adding the listener. - See Also:
-
EventContext.removeNamingListener(javax.naming.event.NamingListener)
,DirContext.search(javax.naming.Name, java.lang.String, javax.naming.directory.SearchControls)
addNamingListener
void addNamingListener(String target, String filter, SearchControls ctls, NamingListener l) throws NamingException
Adds a listener for receiving naming events fired when objects identified by the search filter filter
at the object named by the string target name are modified. See the overload that accepts a Name
for details of how this method behaves.
- Parameters:
-
target
- The nonnull string name of the object resolved relative to this context. -
filter
- The nonnull string filter (see RFC2254). -
ctls
- The possibly null search controls. If null, the default search controls is used. -
l
- The nonnull listener. - Throws:
-
NamingException
- If a problem was encountered while adding the listener. - See Also:
-
EventContext.removeNamingListener(javax.naming.event.NamingListener)
,DirContext.search(java.lang.String, java.lang.String, javax.naming.directory.SearchControls)
addNamingListener
void addNamingListener(Name target, String filter, Object[] filterArgs, SearchControls ctls, NamingListener l) throws NamingException
Adds a listener for receiving naming events fired when objects identified by the search filter filter
and filter arguments at the object named by the target are modified. The scope, returningObj flag, and returningAttributes flag from the search controls ctls
are used to control the selection of objects that the listener is interested in, and determines what information is returned in the eventual NamingEvent
object. Note that the requested information to be returned might not be present in the NamingEvent
object if they are unavailable or could not be obtained by the service provider or service.
- Parameters:
-
target
- The nonnull name of the object resolved relative to this context. -
filter
- The nonnull string filter (see RFC2254). -
filterArgs
- The possibly null array of arguments for the filter. -
ctls
- The possibly null search controls. If null, the default search controls are used. -
l
- The nonnull listener. - Throws:
-
NamingException
- If a problem was encountered while adding the listener. - See Also:
-
EventContext.removeNamingListener(javax.naming.event.NamingListener)
,DirContext.search(javax.naming.Name, java.lang.String, java.lang.Object[], javax.naming.directory.SearchControls)
addNamingListener
void addNamingListener(String target, String filter, Object[] filterArgs, SearchControls ctls, NamingListener l) throws NamingException
Adds a listener for receiving naming events fired when objects identified by the search filter filter
and filter arguments at the object named by the string target name are modified. See the overload that accepts a Name
for details of how this method behaves.
- Parameters:
-
target
- The nonnull string name of the object resolved relative to this context. -
filter
- The nonnull string filter (see RFC2254). -
filterArgs
- The possibly null array of arguments for the filter. -
ctls
- The possibly null search controls. If null, the default search controls is used. -
l
- The nonnull listener. - Throws:
-
NamingException
- If a problem was encountered while adding the listener. - See Also:
