Class Tuple2<A,B>

java.lang.Object

org.whaka.util.function.Tuple2<A,B>

All Implemented Interfaces:

java.util.Map.Entry<A,B>

public final class Tuple2<A,B>
extends java.lang.Object
implements java.util.Map.Entry<A,B>

Final immutable container for 2 objects of different types.

Values might be accessed directly: _1 and _2, or thru getters: get_1() and get_2().

Class also implements Map.Entry, so getters: getKey() and getValue() are available.
