Interface Pair<T1,T2>

All Superinterfaces:
Comparable<Pair<T1,T2>>, Serializable
All Known Subinterfaces:
Twin<T>
public interface Pair<T1,T2> extends Serializable, Comparable<Pair<T1,T2>>
A Pair is a container that holds two related objects. It is the equivalent of an Association in Smalltalk, or an implementation of Map.Entry in the JDK. An instance of this interface can be created by calling Tuples.pair(Object, Object) or Tuples.twin(Object, Object).
