    Description copied from interface: RMIConnection
    
    Handles the method MBeanServerConnection.isInstanceOf(ObjectName, String).
    
    Specified by:
    
    isInstanceOf in interface RMIConnection
    
    Parameters:
    name - The ObjectName of the MBean.
    className - The name of the class.
    delegationSubject - The Subject containing the delegation principals or null if the authentication principal is used instead.

  - addNotificationListeners
    public Integer[] addNotificationListeners(ObjectName[] names, MarshalledObject[] filters, Subject[] delegationSubjects) throws InstanceNotFoundException, IOException
    
    Description copied from interface: RMIConnection
    
    Handles the method MBeanServerConnection.addNotificationListener(ObjectName, NotificationListener, NotificationFilter, Object).
    
    Register for notifications from the given MBeans that match the given filters. The remote client can subsequently retrieve the notifications using the fetchNotifications method.
    
    For each listener, the original NotificationListener and handback are kept on the client side; in order for the client to be able to identify them, the server generates and returns a unique listenerID. This listenerID is forwarded with the Notifications to the remote client.
    
    If any one of the given (name, filter) pairs cannot be registered, then the operation fails with an exception, and no names or filters are registered.
    
    Specified by:
    
    addNotificationListeners in interface RMIConnection
    
    Parameters:
    names - the ObjectNames identifying the MBeans emitting the Notifications.
    filters - an array of marshalled representations of the NotificationFilters. Elements of this array can be null.
    delegationSubjects - the Subjects on behalf of which the listeners are being added. Elements of this array can be null. Also, the delegationSubjects parameter itself can be null, which is equivalent to an array of null values with the same size as the names and filters arrays.
    
    Returns:
    an array of listenerIDs identifying the local listeners. This array has the same number of elements as the parameters.
    
    Throws:
    
    InstanceNotFoundException - if one of the names does not correspond to any registered MBean.
    
    IOException - if a general communication exception occurred.
  - addNotificationListener
    public void addNotificationListener(ObjectName name, ObjectName listener, MarshalledObject filter, MarshalledObject handback, Subject delegationSubject) throws InstanceNotFoundException, IOException
    
    Description copied from interface: RMIConnection
    
    Handles the method MBeanServerConnection.addNotificationListener(ObjectName, ObjectName, NotificationFilter, Object). The NotificationFilter parameter is wrapped in a MarshalledObject. The Object (handback) parameter is also wrapped in a MarshalledObject.
    
    Specified by:
    
    addNotificationListener in interface RMIConnection
    
    Parameters:
    name - The name of the MBean on which the listener should be added.
    listener - The object name of the listener which will handle the notifications emitted by the registered MBean.
    filter - The filter object, encapsulated into a MarshalledObject. If filter encapsulated in the MarshalledObject has a null value, no filtering will be performed before handling notifications.
    handback - The context to be sent to the listener when a notification is emitted, encapsulated into a MarshalledObject.
    delegationSubject - The Subject containing the delegation principals or null if the authentication principal is used instead.
    
    Throws:
    
    InstanceNotFoundException - The MBean name of the notification listener or of the notification broadcaster does not match any of the registered MBeans.
    
    IOException - if a general communication exception occurred.

    Description copied from interface: RMIConnection
    
    Handles the removeNotificationListener(ObjectName, NotificationListener) and removeNotificationListener(ObjectName, NotificationListener, NotificationFilter, Object) methods.
    
    This method removes one or more NotificationListeners from a given MBean in the MBean server.
    
    The NotificationListeners are identified by the IDs which were returned by the RMIConnection.addNotificationListeners(ObjectName[], MarshalledObject[], Subject[]) method.

    delegationSubject - The Subject containing the delegation principals or null if the authentication principal is used instead.
    
    Throws:
    
    InstanceNotFoundException - if the given name does not correspond to any registered MBean.
    
    ListenerNotFoundException - if one of the listeners was not found on the server side. This exception can happen if the MBean discarded a listener for some reason other than a call to MBeanServer.removeNotificationListener.
    
    IOException - if a general communication exception occurred.

  - fetchNotifications
    public NotificationResult fetchNotifications(long clientSequenceNumber, int maxNotifications, long timeout) throws IOException
    
    Description copied from interface: RMIConnection
    
    Retrieves notifications from the connector server. This method can block until there is at least one notification or until the specified timeout is reached. The method can also return at any time with zero notifications.
    
    A notification can be included in the result if its sequence number is no less than clientSequenceNumber and this client has registered at least one listener for the MBean generating the notification, with a filter that accepts the notification. Each listener that is interested in the notification is identified by an Integer ID that was returned by RMIConnection.addNotificationListeners(ObjectName[], MarshalledObject[], Subject[]).
    
    Specified by:
    
    fetchNotifications in interface RMIConnection
    
    Parameters:
    clientSequenceNumber - the first sequence number that the client is interested in. If negative, it is interpreted as meaning the sequence number that the next notification will have.
    maxNotifications - the maximum number of different notifications to return. The TargetedNotification array in the returned NotificationResult can have more elements than this if the same notification appears more than once. The behavior is unspecified if this parameter is negative.
    timeout - the maximum time in milliseconds to wait for a notification to arrive. This can be 0 to indicate that the method should not wait if there are no notifications, but should return at once. It can be Long.MAX_VALUE to indicate that there is no timeout. The behavior is unspecified if this parameter is negative.
    
    Returns:
    A NotificationResult.
    
    Throws:
    
    IOException - if a general communication exception occurred.
  - toString
    public String toString()
    
    Returns a string representation of this object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read.
    
    Overrides:
    
    toString in class Object
    
    Returns:
    a String representation of this object.
