Method Summary
Bool_t	AddClient(const char * client, const char * host, Go4CommandMode_t role)           adds client task of name to manager: create server task handler and try to connect to client Command execution role depends on previous login passowrd
Bool_t	AddTaskHandler(TGo4TaskHandler* han)           adds external task handler to array
Go4CommandMode_t	ClientLogin()           Check account and password of the client that requests a connection to this server.
Int_t	ConnectClient(const char * client, const char * host, Go4CommandMode_t role)           used by connector runnable to wait for a client request to connect to this server task.
Int_t	DisConnectClient(const char * name, Bool_t clientwait)           disonnect an existing client by name, wait for negotiation OK if clientwait is true
Int_t	DisConnectClient(TGo4TaskHandler* taskhandler, Bool_t clientwait)           disonnect an existing client by name, wait for negotiation OK if clientwait is true
TGo4TaskHandler*	GetLastTaskHandler()           returns last task handler in list
TMutex*	GetMutex()
UInt_t	GetNegotiationPort()           returns the portnumber for client server negotiation port which is actually used by the running taskmanager
const UInt_t	GetTaskCount()           Number of entries in taskhandler list, i.e. number of connected clients
TGo4TaskHandler*	GetTaskHandler(const char * name)           returns certain task handler by name
Bool_t	HasControllerTask()
TGo4TaskHandler*	NewTaskHandler(const char * name)           creates new task handler with given name and adds it into array
TGo4TaskHandler*	NextTaskHandler(Bool_t reset)           For iteration over all connected task handlers.
private synchronized TGo4TaskManager&	operator=(const TGo4TaskManager& right)
Bool_t	RemoveTaskHandler(const char * name)           removes task handler from array by name
Int_t	ServeClient()           used by connector runnable to wait for a client connect/disonnect request

Field Detail

fbClientIsRemoved

private Bool_t fbClientIsRemoved

True if the last specified client is removed from server.
flag is set by connector thread who performs the DisconnectClient
of TaskManager; is reset by WaitForClientRemoved method.

private Bool_t fbHasControllerConnection

true if this server already has one connection to a
master client that has the controller role. Only one
controller or administrator taskhandler is allowed per server.

public const static const Int_t fgiDISCONCYCLES

cycles to wait for client disconnection

public const static const UInt_t fguDISCONTIME

time for each disonnection wait cycle

private UInt_t fuNegotiationPort

port number for the server client negotiation connections

private UInt_t fuTaskCount

private TMutex* fxListMutex

private TGo4ServerTask* fxServer

private TIterator* fxTaskIter

Iterator over list of tasks.

private TObjArray* fxTaskList

public TGo4TaskManager(const char * name, TGo4ServerTask* server, UInt_t negotiationport)

private TGo4TaskManager()

private TGo4TaskManager(const TGo4TaskManager& right)

public virtual synchronized ~TGo4TaskManager()

public Bool_t AddClient(const char * client, const char * host, Go4CommandMode_t role)

adds client task of name to manager: create server task handler and try to connect to client
Command execution role depends on previous login passowrd

public Bool_t AddTaskHandler(TGo4TaskHandler* han)

adds external task handler to array

public Go4CommandMode_t ClientLogin()

Check account and password of the client that requests a
connection to this server. Return value specifies
client access priorities as defined in TGo4Command.h
Returns 0 in case of incorrect login.

public Int_t ConnectClient(const char * client, const char * host, Go4CommandMode_t role)

used by connector runnable to wait for a client request to
connect to this server task. May specify mode of allowed commands
in case of client is master.

public Int_t DisConnectClient(const char * name, Bool_t clientwait)

disonnect an existing client by name, wait for negotiation OK
if clientwait is true

public Int_t DisConnectClient(TGo4TaskHandler* taskhandler, Bool_t clientwait)

disonnect an existing client by name, wait for negotiation OK
if clientwait is true

public TGo4TaskHandler* GetLastTaskHandler()

returns last task handler in list

public TMutex* GetMutex()

public UInt_t GetNegotiationPort()

returns the portnumber for client server
negotiation port which is actually used by
the running taskmanager

public const UInt_t GetTaskCount()

Number of entries in taskhandler list, i.e. number of connected clients

public TGo4TaskHandler* GetTaskHandler(const char * name)

returns certain task handler by name

public Bool_t HasControllerTask()

public TGo4TaskHandler* NewTaskHandler(const char * name)

creates new task handler with given name and adds it into array

public TGo4TaskHandler* NextTaskHandler(Bool_t reset)

For iteration over all connected task handlers. If
reset is true, internal iterator will be reset. Otherwies,
continue iterating list until last entry. Returns 0 when
iteration finishes.

private synchronized TGo4TaskManager& operator=(const TGo4TaskManager& right)

public Bool_t RemoveTaskHandler(const char * name)

removes task handler from array by name

public Int_t ServeClient()

used by connector runnable to wait for a client connect/disonnect request

public Int_t WaitForClientRemoved()
