createStep
Description copied from interface:ProcessingFilter
Creates a new ProcessingStep based on a sequence of command-line arguments. TheargIt
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 aProcessingStep
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:
