Function documentation

TFileInfo(const char* url = 0, Long64_t size = -1, const char* uuid = 0, const char* md5 = 0, TObject* meta = 0)
 Constructor.
~TFileInfo()
 Destructor.
TUrl * GetCurrentUrl()
 Return the current url.
TUrl * NextUrl()
 Iterator function, start iteration by calling ResetUrl().
 The first call to NextUrl() will return the 1st element,
 the seconde the 2nd element etc. Returns 0 in case no more urls.
TUrl * FindByUrl(const char* url)
 Find an element from a URL. Returns 0 if not found.
Bool_t AddUrl(const char* url, Bool_t infront = kFALSE)
 Add a new URL. If 'infront' is TRUE the new url is pushed at the beginning
 of the list; otherwise is pushed back.
 Returns kTRUE if successful, kFALSE otherwise.
Bool_t RemoveUrl(const char* url)
 Remove an URL. Returns kTRUE if successful, kFALSE otherwise.
Bool_t AddMetaData(TObject* meta)
 Add's a meta data object to the file info object. The object will be
 adopted by the TFileInfo and should not be deleted by the user.
 Typically objects of class TFileInfoMeta or derivatives should be added,
 but any class is accepted.
 Returns kTRUE if successful, kFALSE otherwise.
Bool_t RemoveMetaData(const char* meta = 0)
 Remove the metadata obeject. If meta is 0 remove all meta data objects.
 Returns kTRUE if successful, kFALSE otherwise.
TFileInfoMeta * GetMetaData(const char* meta = 0) const
 Get meta data object with specified name. If meta is 0
 get first meta data object. Returns 0 in case no
 suitable meta data object is found.
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.
TFileInfo(const TFileInfo& )
TFileInfo& operator=(const TFileInfo& )
void ResetUrl()
{ fCurrentUrl = (TUrl*)fUrlList->First(); }
TUrl * GetFirstUrl()
{ return (TUrl*)fUrlList->First(); }
Int_t GetNUrls()
{ return fUrlList->GetEntries(); }
Long64_t GetSize()
{ return fSize; }
TUUID * GetUUID()
{ return fUUID; }
TMD5 * GetMD5()
{ return fMD5; }
TList * GetMetaDataList()
{ return fMetaDataList; }
void SetSize(Long64_t size)
{ fSize = size; }
Bool_t IsSortable()
{ return kTRUE; }
