protected  String[] flatten(Options options, String[] arguments, boolean stopAtNonOption)
          This flatten method does so using the following rules: If an Option exists for the first character of the arguments entry AND an Option does not exist for the whole argument then add the first character as an option to the processed tokens list e.g.
private  void init()
          Resets the members to their original state i.e.

Resets the members to their original state i.e. remove all of tokens entries.


flatten

protected String[] flatten(Options options,
                           String[] arguments,
                           boolean stopAtNonOption)

This flatten method does so using the following rules:

  1. If an Option exists for the first character of the arguments entry AND an Option does not exist for the whole argument then add the first character as an option to the processed tokens list e.g. "-D" and add the rest of the entry to the also.
  2. Otherwise just add the token to the processed tokens list.

Specified by:
flatten in class Parser
Parameters:
options - The Options to parse the arguments by.
stopAtNonOption - specifies whether to stop flattening when a non option has been encountered
Returns:
a String array of the flattened arguments
