Function documentation

TFileInfo(const char* url = 0, Long64_t size = -1, const char* uuid = 0, const char* md5 = 0, Long64_t entries = -1, Long64_t first = -1, Long64_t last = -1, TObject* meta = 0)
 Constructor.
~TFileInfo()
 Destructor.
TUrl * NextUrl()
 Iterator Function, init Iteration with ResetUrl().
 The first Call to NextUrl() will return the 1st element,
 the seconde the 2nd element aso.
TUrl * FindByUrl(const char* url)
 Find an element from a URL.
Bool_t AddUrl(const char* url)
 Add a new URL
Bool_t RemoveUrl(const char* url)
 Remove an URL.
void AddMetaDataObject(TObject* obj)
 Add's a meta data object to the file info object
void RemoveMetaDataObject()
 Remove all the metadata obejects.
Int_t Compare(const TObject* obj) const
 Compare TFileInfo object by their first urls.
void Print(Option_t* options = "") const
 Print information about this object.
TList * CreateList(const char* file)
 Open the text 'file' and create TList of TFileInfo objects.
 The 'file' must include one url per line.
 The function returns a TList of TFileInfos (possibly empty) or
 0 if 'file' can not be opened.
TList * CreateListMatching(const char* files)
 Find all the files matching 'files' and return a TList of corresponding
 TFileInfo objects. 'files' can include wildcards after the last slash.
 If 'files' is the full path of a file, a list with only one element is
 created. If no files match the selection, 0 is returned
TFileInfo(const TFileInfo& )
TFileInfo& operator=(const TFileInfo& )
void ResetUrl()
{ fCurrentUrl = (TUrl*)fUrlList->First(); }
TUrl * GetCurrentUrl()
{ return ((fCurrentUrl)?fCurrentUrl:0) ; }
TUrl * GetFirstUrl()
{ return (TUrl*)fUrlList->First(); }
Long64_t GetSize()
{ return fSize; }
Long64_t GetEntries()
{ return fEntries; }
Long64_t GetFirst()
{ return fFirst; }
Long64_t GetLast()
{ return fLast; }
TUUID * GetUUID()
{ return fUUID; }
TMD5 * GetMD5()
{ return fMD5; }
TObject * GetMetaObject()
{ return fMetaDataObject; }
void SetFirst(Long64_t first)
{ fFirst = first; }
void SetLast(Long64_t last)
{ fLast = last; }
void SetEntries(Long64_t entries)
{ fEntries = entries; }
Bool_t IsSortable()
{ return kTRUE; }
