Method Detail

• getDescriptionLines

  protected java.lang.String[] getDescriptionLines()

  Specified by:

  getDescriptionLines in class BasicFilter

• createStep

  public ProcessingStep createStep(java.util.Iterator 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. If its usageFrament is blank, it will be filled in later using this mode's usage text.

  Parameters:

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