final
trait
Nothing
extends
Any
Class Nothing
is - together with class
Null
- at the bottom of the
Scala type
hierarchy.
Type Nothing
is a subtype of every other type
(including Null
); there
exist no instances of this type. Even though type
Nothing
is empty, it is nevertheless useful as a
type parameter. For instance, the Scala library defines a value
Nil
of type
List[Nothing]
. Because lists
are covariant in Scala,
this makes Nil
an
instance of List[T]
, for
any element type T
.
