Interface Triple<T1,T2,T3>
-
- Type Parameters:
T1- The type of the first valueT2- The type of the second valueT3- The type of the third value
- All Superinterfaces:
ViewableAsTriple<T1,T2,T3>
public interface Triple<T1,T2,T3> extends ViewableAsTriple<T1,T2,T3>
A triple is a simple composition of three arbitrary values (objects). A triple captures no semantics of the three values, and they are only referred to as "the first", "the second", and "the third" value.
