All Implemented Interfaces:

Iterable<T>, Collection<T>, Set<T>

public class PairSet<T>
extends AbstractSet<T>
implements Set<T>

An unmodifiable Set implementation that is a wrapper around a pair of sets without additional storage for set elements. There may be common elements in two sets which will be not be visible to the outside, i.e. iterator will discard duplicates on-the-fly.
