trait SetProxy
[source: scala/collection/immutable/SetProxy.scala]
trait SetProxy[A]
extends Set[A] with SetProxyLike[A, Set[A]]

This is a simple wrapper class for scala.collection.immutable.Set.

It is most useful for assembling customized set abstractions dynamically using object composition and forwarding.
