public ProcessingStep createStep(java.util.Iterator<java.lang.String> argIt)
```
    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.
    
    Specified by:
    
    createStep in interface ProcessingFilter
    
    Parameters:
    
    argIt - iterator over command-line arguments positioned at the first one
  - wrap

    Description copied from interface: ProcessingStep
