Known Subclasses:

is a RowIterator base for RowIterators reading files.

It analyzes the sourceToken to see if it's a string, in which case it opens it as a file name and leaves the file object in self.inputFile.

Otherwise, it assumes sourceToken already is a file object and binds it to self.inputFile. It then tries to come up with a sensible designation for sourceToken.

It also inspects the parent grammar for a gunzip attribute. If it is present and true, the input file will be unzipped transparently.
