Function documentation

TFFitsIO(TFIOElement* element, const char* fileName)
 opens a file or creates a new file if the file does not exist and creates
 a new HDU in the FITS file.
TFFitsIO(TFIOElement* element, void* fptr, int cycle)
 constructor
~TFFitsIO()
 destructor
TFIOElement * TFRead(const char* fileName, const char* name, Int_t cycle = 0, FMode mode = kFRead, TClass* classType = NULL)
 tries to open an element in a FITS file and converts it into TFIOElement
 or one of its derived classes.
 In case there is a problem an Error is written to TFError and NULL is
 returned.
Bool_t IsOpen()
 return kTRUE if an element is successfull open
const char * GetFileName()
 returns the filename of an element.
 returns NULL if the element is not open or in case of a cfitsio error
Int_t GetCycle()
 returns the cycle number == HDU number.
 First element in FITS file (primary header) has cycle 1
void CreateElement()
 creates a new element
Int_t DeleteElement()
 deletes this HDU and deletes the file if if is the last HDU
 Note: cfitsio will replace the first HDU == primary array by
 an empty one if this primary array should be deleted.
Int_t SaveElement(Int_t compLevel = -1)
 saves the current element into the FITS file
TFFitsIO(const TFFitsIO& )
{}
TFFitsIO(TFIOElement* element, const char* fileName)
void SetCompressionLevel(Int_t level)
{}
Int_t GetCompressionLevel()
{return 0;}
