createStep

public ProcessingStep createStep(Iterator<String> argIt)
                          throws ArgException

Description copied from interface: ProcessingFilter

Creates a new ProcessingStep based on a sequence of command-line arguments. The argIt argument is an iterator over the command-line arguments positioned just before any arguments intended for this filter. If legal, any that can be comprehended by this filter should be read (iterated over) and removed, and a ProcessingStep should accordingly be returned. In the case of a successful return, it is essential that no arguments other than the ones intended for this filter are read from the iterator.

If the argument list is badly-formed as far as this filter is concerned, an ArgException should be thrown.

Parameters:

argIt - iterator over command-line arguments positioned at the first one

Throws:

ArgException
