This method may start a gui window that contains the output of the slave task.

) [virtual]

Start connection to the slave.
If master is server, this will launch a client slave on the remotehost, by means of LaunchClient method of TGo4ServerTask. If master is client, this method will try to connect to an existing slave (analysis) server. Parameters: name - arbitrary name of slave remotehost - nodename of slave process negport - negotiationport (if slave already running as server ) remotedir - directory to start slave application remotecommand - executable name of slave mode - embedding mode (Qt, Xterm - ssh, rsh) of the slave output startserver - start slave server itself before connecting this master to it role - master role when connecting to slave server passwd - login passwd

Bool_t TGo4Master::DisconnectSlave ( const char * name = 0,

Bool_t waitforslave = kTRUE

) [virtual]

Disconnect slave process.
If master is server, this will remove taskhandler of specified name, or current task handler. If master is client, this will remove the existing client connection (name argument is nop). If waitforslave is false, master will not wait for slave disconnect acknowledgement (fast disconnect mode).

) [virtual]

method using a shell script to create a new linux xterm with a slave executable as server.
May be overridden by specialised subclass methods to call the script appropriate for the respective client. mode specifiers: Bit1=0 - use rsh for starting analysis client Bit1=1 - use ssh for starting analysis slave Bit2=0 - client in xterm window Bit2=1 - client without xterm in same shell as gui Bit3=0 - client outside gui mainframe (not implemented) Bit3=1 - client embedded in gui mainframe (not implemented) specify these bits respectively, with kSecureShell, kNoXterm, kGuiEmbed
