Function documentation

TFIOElement()
 Default constructor. The element is not associated with a element
 in a file.
 Don't use this constructor. The element should have at least a name.
TFIOElement(const char * name)
 The element is not associated with an element in a file.
 It exist only in memory. name is the id of the new element.
TFIOElement(const char* name, const char* fileName)
 A new element is created. It is associated with an element in a
 file. name is the id of the new element.
 fileName is the file name of the ASRO, ROOT or FITS file with this new
 element. The file  may already exist or will be created. Other objects
 with the same name can exist without problem in the same file. Each object
 with the same name has a unique cycle number. Use GetCycle() to ask for
 this cycle number. Use the function TFRead() to read and update an already
 existing element from a ASRO, a ROOT or a FITS file.
TFIOElement(const TFIOElement & ioelement)
 Copy constructor. But even if the input element is associated with an
 element in a file, this new table is NOT associated with this or
 an other element in a file. It will exist only in memory, but can be
 saved in a new file using the SaveElement() method.
~TFIOElement()
 The associated file is closed, the element is NOT updated. Use
 SaveElement() to update the changes in the file.
void NewFile(const char* fileName)
 protected function to create a new element in a file
Int_t SaveElement(const char* fileName = NULL, Int_t compLevel = -1)
 Updates the element in the file with the data of this element in
 memory. If fileName is defined the old file is closed and the element
 is written into this new file named fileName.
 compLevel defines the compression level in the ASRO or ROOT file. To set
 compLevel and to update the element in the same file set fileName
 to an empty string "".
 This function without any parameter has to be used to update the
 file with any change of the element in memory.
void CloseElement()
 Closes the element in the associated file. It does not update the
 element in the file. The element still exist in memory after
 a call of this function.
Int_t DeleteElement(Bool_t updateMemory = kFALSE)
 Deletes the element in the file, but not in memory.
 Closes the file and deletes the file if this element is the
 last element in the file.
 Updated the element in memory before the file is deleted if
 updateMemory is set to kTRUE. The default is kFALSE.
void Print(Option_t* option = "") const
  Prints Class name, name of object and file name and cycle number
  of object if if is connected to a file.
  Calls Print function of TFHeader to print the header attributes
void SetIO(TFVirtualIO* io)
{fio = io;}
void SetFileAccess(FMode mode)
{fFileAccess = mode;}
Bool_t IsFileConnected()
{return fio != NULL && fio->IsOpen();}
const char * GetFileName()
{return fio ? fio->GetFileName() : NULL;}
Int_t GetCycle()
{return fio ? fio->GetCycle() : 0;}
void SetCompressionLevel(Int_t level)
{if (fio) fio->SetCompressionLevel(level);}
Int_t GetCompressionLevel()
{return fio ? fio->GetCompressionLevel() : 0;}
void UpdateMemory()
{}
