java.lang.Object
   javax.management.NotificationFilterSupport

NotificationFilterSupport
public class NotificationFilterSupport implements NotificationFilter,Serializable(Code)
Provides an implementation of the javax.management.NotificationFilter interface. The filtering is performed on the notification type attribute.

This class manages a list of enabled notification types. A method allows users to enable/disable as many notification types as required.

Then, before sending a notification to a listener registered with a filter, the notification broadcaster compares this notification type with all notification types enabled by the filter. The notification will be sent to the listener only if its filter enables this notification type.

Example:

 NotificationFilterSupport myFilter = new NotificationFilterSupport();
 myFilter.enableType("my_example.my_type");
 myBroadcaster.addListener(myListener, myFilter, null);
 
The listener myListener will only receive notifications the type of which equals/starts with "my_example.my_type".
See Also:   javax.management.NotificationBroadcaster.addNotificationListener


Field Summary
protected  VectorenabledTypes
     Vector that contains the enabled notification types.

Constructor Summary
public  NotificationFilterSupport()
    

Method Summary
public  voiddisableAllTypes()
     Disables all the notification types.
public  voiddisableType(String prefix)
     Disables all the notifications whose type matches the specified prefix to be sent to the listener.
public  voidenableType(String prefix)
     Enables all the notifications whose type matches the specified prefix to be sent to the listener.
public  VectorgetEnabledTypes()
     Gets all the enabled notification types for this filter.
public  booleanisNotificationEnabled(Notification notification)
     Invoked before sending the specified notification to the listener. This filter compares the notification type with each enabled type. If the notification type matches one of the enabled type, the notification has to be sent to the listener and this method returns true.
Parameters:
  notification - The notification to be sent.

Field Detail
enabledTypes
protected Vector enabledTypes(Code)
Vector that contains the enabled notification types. The default value is an empty vector.




Constructor Detail
NotificationFilterSupport
public NotificationFilterSupport()(Code)
Creates a NotificationFilterSupport Default constructor




Method Detail
disableAllTypes
public void disableAllTypes()(Code)
Disables all the notification types.



disableType
public void disableType(String prefix)(Code)
Disables all the notifications whose type matches the specified prefix to be sent to the listener. If the specified prefix is not in the list of enabled notification types, this method has no effect.
Parameters:
  prefix - The prefix.



enableType
public void enableType(String prefix) throws IllegalArgumentException(Code)

Parameters:
  prefix - The prefix.
throws:
  IllegalArgumentException - The prefix parameter is null.



getEnabledTypes
public Vector getEnabledTypes()(Code)
Gets all the enabled notification types for this filter. The list containing all the enabled notification types.



isNotificationEnabled
public boolean isNotificationEnabled(Notification notification)(Code)
Invoked before sending the specified notification to the listener. This filter compares the notification type with each enabled type. If the notification type matches one of the enabled type, the notification has to be sent to the listener and this method returns true.
Parameters:
