in scala.collection.immutable
object Set

object Set
extends java.lang.Object
with scala.ScalaObject

This class represents immutable sets. Concrete set implementations just have to provide functionality for the abstract methods in scala.collection.Set as well as for + and -.

Note that abstract immutable.Set's are not covariant in their type parameter. This is because some subclasses cannot support the + method for arbitrary types.
