Value Members From scala.Unit

def box(x: Unit): BoxedUnit

Transform a value type into a boxed reference type.

  • x
    • the Unit to be boxed
  • returns
    • a scala.runtime.BoxedUnit offering x as its underlying value.

(defined at scala.Unit)

def unbox(x: AnyRef): Unit

Transform a boxed type into a value type. Note that this method is not typesafe: it accepts any Object, but will throw an exception if the argument is not a scala.runtime.BoxedUnit.

  • x
    • the scala.runtime.BoxedUnit to be unboxed.
  • returns
    • the Unit value ()
  • Exceptions thrown
    • ClassCastException if the argument is not a scala.runtime.BoxedUnit (defined at scala.Unit)
