FILE_TYPE
Enumerate the supported file types.
vtkTypeBool GetSwapBytes()
Set/Get the byte swapping to explicitly swap the bytes of a file.
int FileType
Used to decide which reader should be used.
size_t Count
Count of the number of alliquots processed.
Store vtkAlgorithm input/output information.
virtual int RequestData(vtkInformation *request, vtkInformationVector **inputVector, vtkInformationVector *outputVector)
This is called by the superclass.
void SetFileTypeToText()
Get/Set the file type.
