Type Constructor

  1. def default(v: ⇒ A): Opt[A]

    Default value

    Default value

    Only if there is no value, creates new option with default value

    var o : Opt[String] = "foo"

o = o.default("bar")

println(o)  // Prints: Opt(foo)

o = \/

o = o.default("bar")

println(o)  // Prints: Opt(bar)

  2. def orOpt(that: ⇒ Opt[A]): Opt[A]

    Default option

    Default option

    Returns this Opt, or if it is void, then given default

    var o1 : Opt[String] = "foo"
val o2 : Opt[String] = "bar"

println(o1 orOpt o2)  // Prints: Opt(foo)

o1 = \/

println(o1 orOpt o2)  // Prints: Opt(bar)
