TSlave

This class describes a PROOF slave server.
It contains information like the slaves host name, ordinal number,
performance index, socket, etc. Objects of this class can only be
created via TProof member functions.

Function documentation

TSlave(const char* host, const char* ord, Int_t perf, const char* image, TProof* proof, Int_t stype, const char* workdir, const char* msd)
 Create a PROOF slave object. Called via the TProof ctor.
TSlave(const TSlave& s)
 Default constructor used by derived classes
void Init(const char* host, Int_t port, Int_t stype)
 Init a PROOF slave object. Called via the TSlave ctor.
 The Init method is technology specific and is overwritten by derived
 classes.
Int_t SetupServ(Int_t stype, const char* conffile)
 Init a PROOF slave object. Called via the TSlave ctor.
 The Init method is technology specific and is overwritten by derived
 classes.
void Init(TSocket* s, Int_t stype)
 Init a PROOF slave object using the connection opened via s. Used to
 avoid double opening when an attempt via TXSlave found a remote proofd.
~TSlave()
 Destroy slave.
void Close(Option_t* opt = "")
 Close slave socket.
Int_t Compare(const TObject* obj) const
 Used to sort slaves by performance index.
void Print(Option_t* option = "") const
 Printf info about slave.
void SetInputHandler(TFileHandler* ih)
 Adopt and register input handler for this slave. Handler will be deleted
 by the slave.
Int_t OldAuthSetup(Bool_t master, TString wconf)
 Setup authentication related stuff for old versions.
 Provided for backward compatibility.
TSlave * Create(const char* url, const char* ord, Int_t perf, const char* image, TProof* proof, Int_t stype, const char* workdir, const char* msd)
 Static method returning the appropriate TSlave object for the remote
 server.
Int_t Ping()
 Ping the remote master or slave servers.
 Returns 0 if ok, -1 in case of error
void Interrupt(Int_t type)
 Send interrupt OOB byte to master or slave servers.
 Returns 0 if ok, -1 in case of error
void StopProcess(Bool_t abort, Int_t timeout)
 Sent stop/abort request to PROOF server.
TObjString * SendCoordinator(Int_t kind, const char* msg = 0, Int_t int2 = 0)
 Send message to intermediate coordinator. Only meaningful when there is one,
 i.e. in XPD framework
void SetAlias(const char* alias)
 Set an alias for this session. If reconnection is supported, the alias
 will be communicated to the remote coordinator so that it can be recovered
 when reconnecting
