scala.Unit

abstract final class Unit extends AnyVal

Unit is a subtype of scala.AnyVal. There is only one value of type Unit , () , and it is not represented by any object in the underlying runtime system. A method with return type Unit is analogous to a Java method which is declared void .

Value Members From scala.Any

final def ##(): Int

Equivalent to x.hashCode except for boxed numeric types and null . For numerics, it returns a hash value which is consistent with value equality: if two value type instances compare as true, then ## will produce the same hash value for each of them. For null returns a hashcode where null.hashCode throws a NullPointerException .

  • returns
    • a hash value consistent with ==
  • Definition Classes
    • Any (defined at scala.Any###)
