Detailed Description

This class controls a client application running in a task which is controlled by another server task via transport channels which are held by a task handler object. Apart from the transport threads, the application class which inherits from client task may provide working threads to serve the data queues and do the actual work

Bool_t TGo4ClientTask::DisconnectServer ( Bool_t isterminating = kFALSE )

Disconnect the current server task, but do not terminate the client. Return value indicates success state: true if disconnected, false if connection is still existing. If isterminating=true, work threads are not restarted again.
