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()
 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
