Member Function Documentation

CreateSession()

TProof * TProofMgrLite::CreateSession ( const char *  cfg = 0, const char *  = 0, Int_t  loglevel = -1  )

virtual

Create a new session.

Reimplemented from TProofMgr.

Definition at line 51 of file TProofMgrLite.cxx.

GetSessionLogs()

TProofLog * TProofMgrLite::GetSessionLogs ( Int_t  isess = 0, const char *  stag = 0, const char *  pattern = "-v | SvcMsg", Bool_t  rescan = kFALSE  )

virtual

Get logs or log tails from last session associated with this manager instance.

The arguments allow to specify a session different from the last one: isess specifies a position relative to the last one, i.e. 1 for the next to last session; the absolute value is taken so -1 and 1 are equivalent. stag specifies the unique tag of the wanted session The special value stag = "NR" allows to just initialize the TProofLog object w/o retrieving the files; this may be useful when the number of workers is large and only a subset of logs is required. If 'stag' is specified 'isess' is ignored (unless stag = "NR"). If 'pattern' is specified only the lines containing it are retrieved (remote grep functionality); to filter out a pattern 'pat' use pattern = "-v pat". Returns a TProofLog object (to be deleted by the caller) on success, 0 if something wrong happened.

Reimplemented from TProofMgr.

Definition at line 129 of file TProofMgrLite.cxx.

ReadBuffer() [1/2]

TObjString * TProofMgrLite::ReadBuffer ( const char *  fin, const char *  pattern  )

virtual

Read lines containing 'pattern' in 'file'.

Returns a TObjString with the content or 0, in case of failure

Reimplemented from TProofMgr.

Definition at line 353 of file TProofMgrLite.cxx.

ReadBuffer() [2/2]

TObjString * TProofMgrLite::ReadBuffer ( const char *  fin, Long64_t  ofs, Int_t  len  )

virtual

Read 'len' bytes from offset 'ofs' of the local file 'fin'.

Returns a TObjString with the content or 0, in case of failure

Reimplemented from TProofMgr.
