Class Triplets<K1,K2,V>

java.lang.Object

com.atomicleopard.expressive.collection.Triplets<K1,K2,V>

Type Parameters:

K1 -

K2 -

V -

public class Triplets<K1,K2,V>
extends Object

Triplets is a simple implementation allowing three correlated values to be stored against eachother. It is identical in behaviour to a Map with two key values, rather than one.
