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.
TSlave(const char *url, const char *ord, Int_t perf,
const char *image, TProof *proof, Int_t stype,
const char *workdir, const char *msd)
: fImage(image), fProofWorkDir(workdir),
fWorkDir(workdir), fPort(-1),
fOrdinal(ord), fPerfIdx(perf),
fProtocol(0), fSocket(0), fProof(proof),
fInput(0), fBytesRead(0), fRealTime(0),
fCpuTime(0), fSlaveType((ESlaveType)stype), fStatus(0),
fParallel(0), fMsd(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.
void 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 *) 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
TObjString* SendCoordinator(Int_t, const char *)
Send message to intermediate coordinator. Only meaningful when there is one,
i.e. in XPD framework
void SetAlias(const char *)
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
