Function documentation

TXNetFileStager(const char* stager = "")
 Constructor. Init a TXNetSystem instance to the XRD system.
Bool_t IsStaged(const char* path)
 Check if the file defined by 'path' is ready to be used.
Bool_t Stage(TCollection* pathlist, Option_t* opt = 0)
 Issue a stage request for file defined by 'path'. The string 'opt'
 defines 'option' and 'priority' for 'Prepare': the format is
    opt = "option=o priority=p".
Bool_t Stage(const char* path, Option_t* opt = 0)
 Issue a stage request for file defined by 'path'. The string 'opt'
 defines 'option' and 'priority' for 'Prepare': the format is
                opt = "option=o priority=p".
void GetPrefix(const char* url, TString& pfx)
 Isolate prefix in url
void Print(Option_t* option = "") const
 Print basic info about this stager
Int_t Locate(const char* path, TString& endpath)
 Get actual end-point url for a path
 Returns 0 in case of success and 1 if any error occured
Int_t LocateCollection(TFileCollection* fc, Bool_t addDummyUrl = kFALSE)
 Bulk locate request for a collection of files. A noop prepare command is
 issued beforehand to fill redirector's cache, then Locate() is issued on
 each file. Results are saved back to the input collection: when a file is
 found, the staged bit is set to on, and its endpoint URL is added, if
 different from the redirector's URL. If a file is not found, the staged
 bit is set to off.
 If addDummyUrl is kTRUE, in case file is not staged or redirector is
 identical to endpoint URL, a dummy URL is prepended, respectively:
 "noop://redir" and "noop://none".
 If the collection contains URLs with "anchors" (i.e., #fileName.root),
 they are ignored by xrootd.
 The Locate() command preserves anchors, but needs single paths to be full
 URLs beginning with root://.
 Returns < 0 in case of errors, and the number of files processed in case
 of success.
Bool_t Matches(const char* s)
 Returns kTRUE if stager 's' is compatible with current stager.
 Avoids multiple instantiations of the potentially the same TXNetSystem.
TXNetFileStager(const char* stager = "")
Bool_t IsValid() const
{ return (fSystem ? kTRUE : kFALSE); }
