    - #### MBeanServerNotificationFilter

          public MBeanServerNotificationFilter()

      Creates a filter selecting all MBeanServerNotification notifications for all ObjectNames.

  - ### Method Detail

    - #### disableAllObjectNames

          public void disableAllObjectNames()

      Disables any MBeanServerNotification (all ObjectNames are deselected).

    - #### disableObjectName

          public void disableObjectName(ObjectName objectName)
                                 throws IllegalArgumentException

      Disables MBeanServerNotifications concerning given ObjectName.
      Parameters:
        `objectName` - ObjectName no longer of interest
      Throws:
        `IllegalArgumentException` - if the given ObjectName is null

    - #### enableAllObjectNames

          public void enableAllObjectNames()

      Enables all MBeanServerNotifications (all ObjectNames are selected).

    - #### enableObjectName

          public void enableObjectName(ObjectName objectName)
                                throws IllegalArgumentException

      Enables MBeanServerNotifications concerning given ObjectName.
      Parameters:
        `objectName` - ObjectName of interest
      Throws:
        `IllegalArgumentException` - if the given ObjectName is null

    - #### getEnabledObjectNames

          public Vector<ObjectName> getEnabledObjectNames()

      Gets all the ObjectNames enabled.
      Returns:
        Vector of ObjectNames:

        - null means all ObjectNames are implicitly selected, except the ObjectNames explicitly deselected

        - empty means all ObjectNames are deselected, i.e. no ObjectName selected.

    - #### getDisabledObjectNames

          public Vector<ObjectName> getDisabledObjectNames()

      Gets all the ObjectNames disabled.
      Returns:
        Vector of ObjectNames:

        - null means all ObjectNames are implicitly deselected, except the ObjectNames explicitly selected

        - empty means all ObjectNames are selected, i.e. no ObjectName deselected.

    - #### isNotificationEnabled

          public boolean isNotificationEnabled(Notification notif)
                                        throws IllegalArgumentException

      Invoked before sending the specified notification to the listener.

      If:

      - the ObjectName of the concerned MBean is selected (explicitly OR (implicitly and not explicitly deselected))

      AND

      - the type of the operation (registration or unregistration) is selected

      then the notification is sent to the listener.

      Specified by:
