Abstract Value Members

  1. abstract def empty: Optional

    Creates an empty optional value.

  2. abstract def fold[A](oa: Optional, onNone: ⇒ A, onSome: (Value) ⇒ A): A

    Folds optional value just like Option.fold.

  3. abstract def of(value: Value): Optional

    Creates non-empty optional value (should handle nulls as empty).
