Field Detail

fbMainIsRunning

private Bool_t fbMainIsRunning

will just wait on incoming commands without processing main loop.

public TGo4Slave()

public TGo4Slave(const char * name, Bool_t isserver, const char * serverhost, UInt_t negotport)

public virtual synchronized ~TGo4Slave()

public virtual TGo4TaskStatus* CreateStatus()

create a status object with information on the
current (slave) task. this object may be sent to the
master or may be used to restore current status by
memento mechanism

public virtual void ExecuteString(const Text_t* command)

public TGo4ThreadHandler* GetThreadHandler()

public virtual Int_t Initialization()

Overrides the ThreadManager Initialization; is used to setup the
client connections on demand; checks for fbConnectRequest flag

public virtual void KillMain()

Kill the main thread; method to be called from
command, should be overridden in user
implementation

public Bool_t& MainIsRunning()

public TGo4Command* NextCommand()

Delivers next command from command queue.

public virtual void RestartMain()

Restart the main thread; method to be called from
command, should be overridden in user
implementation

public void SendObject(TObject* obj, const char * receiver)

Send object via data channel to the server.

public void SendStatus(TGo4Status* stat, const char * receiver)

General start method of slave application to be called from remote
command; should be re-implemented by application

public virtual void Stop()

General stop method of slave application to be called from remote
command; should be re-implemented by application

public virtual void Terminate(Bool_t termapp)

public virtual void TerminateFast()

protected virtual void UpdateStatus(TGo4TaskStatus* state)

method needed by method
CreateStatus of any status subclasses to
set the values of the clienttask specific
part of the status object.

public void UpdateStatusBuffer()

Create status object and stream it into the
status send buffer. To be executed from
