file sets as stored by Grid file catalogs, by PROOF or any other
collection of TFile names.

Function documentation

TFileCollection(const char* name = 0, const char* title = 0, const char* file = 0, Int_t nfiles = -1, Int_t firstfile = 1)
 TFileCollection constructor. Specify a name and title describing
 the list. If textfile is specified the file is opened and a
 TFileCollection is created containing the files in the textfile.
~TFileCollection()
 Cleanup.
Int_t Add(TFileInfo *info)
 Add TFileInfo to the collection.
Int_t AddFromFile(const char* file, Int_t nfiles = -1, Int_t firstfile = 1)
 Add file names contained in the specified text file.
 The file should contain one url per line; empty lines or lines starting with '#'
 (commented lines) are ignored.
 If nfiles > 0 only nfiles files are added, starting from file 'firstfile' (>= 1).
 The method returns the number of added files.
Int_t Add(const char *dir)
 Add all files matching the specified pattern to the collection.
 'dir' can include wildcards after the last slash, which causes all
 matching files in that directory to be added.
 If dir is the full path of a file, only one element is added.
 Return value is the number of added files.
TFileCollection * GetStagedSubset()
 Creates a subset of the files that have the kStaged & !kCorrupted bit set.
Int_t Update(Long64_t avgsize = -1)
 Update accumulated information about the elements of the collection
 (e.g. fTotalSize). If 'avgsize' > 0, use an average file size of 'avgsize'
 bytes when the size info is not available.
 Also updates the meta data information by summarizing
 the meta data of the contained objects.
 Return -1 in case of any failure, 0 if the total size is exact, 1 if
 incomplete, 2 if complete but (at least partially) estimated.
void Print(Option_t* option = "") const
 Prints the contents of the TFileCollection.
 If option contains "M": prints meta data entries,
 if option contains "F": prints all the files in the collection.
void SetAnchor(const char* anchor)
 Calls TUrl::SetAnchor() for all URLs contained in all TFileInfos.
void SetBitAll(UInt_t f)
 Set the bit for all TFileInfos
void ResetBitAll(UInt_t f)
 Reset the bit for all TFileInfos
const char * GetDefaultTreeName()
 Returns the name of the first tree in the meta data list.
 Returns 0 in case no trees are found in the meta data list.
Long64_t GetTotalEntries(const char* tree) const
 Returns the number of entries for the specified tree (retrieved from meta data).
 If tree is not specified, use the default tree name.
 Returns -1 in case the specified tree is not found.
TFileInfoMeta * GetMetaData(const char* meta = 0) const
 Returns the meta data object with the soecified meta name.
 Returns 0 in case specified meta data is not found.
void SetDefaultMetaData(const char* meta)
 Moves the indicated meta data in the first position, so that
 it becomes efectively the default.
void RemoveMetaData(const char* meta = 0)
 Removes the indicated meta data object in all TFileInfos and this object
 If no name is given all metadata is removed
void Sort()
 Sort the collection.
TObjString * ExportInfo(const char* name = 0)
 Export the relevant info as a string; use 'name' as collection name,
 if defined, else use GetName().
 The output object must be destroyed by the caller
TFileCollection(const TFileCollection& )
TFileCollection& operator=(const TFileCollection& )
THashList * GetList()
{ return fList; }
void SetList(THashList* list)
{ fList = list; }
Long64_t GetTotalSize()
{ return fTotalSize; }
Long64_t GetNFiles()
{ return fNFiles; }
Long64_t GetNStagedFiles()
{ return fNStagedFiles; }
Long64_t GetNCorruptFiles()
{ return fNCorruptFiles; }
Float_t GetStagedPercentage()
{ return (fNFiles > 0) ? 100. * fNStagedFiles / fNFiles : 0; }
Float_t GetCorruptedPercentage()
{ return (fNFiles > 0) ? 100. * fNCorruptFiles / fNFiles : 0; }
