I believe these classes are only used to create "the pipeline". You'll
notice in all the RequestData functions:
int vtkDelimitedTextReader::RequestData(
vtkInformation*,
vtkInformationVector**,
vtkInformationVector* outputVector)
I think they just carry around the input/output types and pointers to the
input/output objects.
Thanks,
David
