    - #### getRaw

          public abstract List<String> getRaw()

      Retrieves a read-only list of the raw arguments. This list may be empty, but is never null. In the case of a standalone application, it is the ordered list of arguments specified on the command line. For named parameters, each <name,value> pair is represented as a single argument of the form: "--name=value".
      Returns:
        a read-only list of raw application arguments

    - #### getUnnamed

          public abstract List<String> getUnnamed()

      Retrieves a read-only list of the unnamed parameters. This list may be empty, but is never null. The named parameters, that is the parameters that are represented as <name,value> pairs, are filtered out.
      Returns:
        a read-only list of unnamed parameters.

    - #### getNamed

          public abstract Map<String,​String> getNamed()

      Retrieves a read-only map of the named parameters. It may be empty, but is never null. Named parameters include any command line arguments of the form: "--name=value".
      Returns:
        a read-only map of named parameters.
