trait
Set[A]
extends Iterable[A] with Set[A] with GenericSetTemplate[A, Set] with SetLike[A, Set[A]]
A generic trait for immutable sets. Concrete set implementations have
to provide functionality for the abstract methods in Set:
def contains(elem: A): Boolean
def iterator: Iterator[A]
def + (elem: A): This
def - (elem: A): This
where This is the type of the set.
