Class UnorderedPair

public class UnorderedPair extends AbstractUnmodifiableCollection implements Serializable

A simple mutable unordered pair implementation. The individual elements may be changed, but the size of this implementation cannot. For convenience, the elements are referred to as "first" and "second", but this has no effect on .equals().
