Abstract Value Members

  1. abstract val argType: V

    Type of parsed argument list.

  2. abstract def parse(s: List[(String, List[String])]): Either[String, Option[A]]

    Takes a list of arguments to all option invocations: for example, "-a 1 2 -a 3 4 5" would produce List(("a",List(1,2)),("a",List(3,4,5))).

    Takes a list of arguments to all option invocations: for example, "-a 1 2 -a 3 4 5" would produce List(("a",List(1,2)),("a",List(3,4,5))).

    • parse returns Left, if there was an error while parsing.
    • if no option was found, it returns Right(None).
    • if option was found, it returns Right(...).
  3. abstract val tag: scala.reflect.api.JavaUniverse.TypeTag[A]

    TypeTag, holding the type for this builder.
