initClientProxy
 public ClientProxy initClientProxy(MonitoringClient v) throws RemoteException


  
 Establishes a ClientProxy for a
 MonitoringClient.

  

    
 Parameters:
    
 v - the MonitoringClient which requires a
 ClientProxy
    
 Returns:
    
 the created ClientProxy
    
 Throws: RemoteException
    
 a general network or Remote
 failure.
  


initCntlClientProxy
 public 
 public CntlClientProxy initCntlClientProxy(ControllingClient v) throws RemoteException


  
 Establishes a CntlClientProxy for a
 ControllingClient.  This implementation allows
 for only one ControllingClient; active control is
 granted with successful completion of this call.

  

    
 Parameters:
    
 v - the ControllingClient which requires a
 CntlClientProxy
    
 Returns:
    
 the created CntlClientProxy or
 null if a ControllingClient has
 already been established.
    
 Throws: RemoteException
    
 a general network or Remote
 failure.

                                    Vector x) throws RemoteException


  
 Basic utility function for disposing of client relationships.

  

    
 Parameters:
    
 v - client to be removed.
    
 x - Vector of currently registered proxies.
    
 Returns:
    
 true if successfully removed, otherwise
 false.
    
 Throws: RemoteException
    
 a general network or Remote
 failure.
  


removeClient
 public boolean removeClient(MonitoringClient v) throws RemoteException

 Returns:
    
 success or failure
    
 Throws: RemoteException
    
 a general network or Remote
 failure.
  


removeCntlClient
b>
 public boolean removeCntlClient(ControllingClient v) throws RemoteException


  
 Removes a ControllingClient. This function should
 also delete the client's CntlClientProxy
