public class ObjectUnion<B,T1 extends B,T2 extends B>
extends ObjectProxy<B>

An instance of a union of type T1 or type T2, of which neither is a superclass of the other. The base type of a union is the most specific class that is a supertype of both, T1 and T2. The union implements the methods of the supertype. ObjectUnion implements the union with base type Object.

Since:

2.0

Constructor Summary

protected	ObjectUnion(T1 base) Creates an object union of type 1 with the given value.
protected	ObjectUnion(T2 base, boolean dummy) Creates an object union of type 2 with the given value.

Method Summary

T1	getBase1() Allows a type safe get of the base value.
T2	getBase2() Allows a type safe get of the base value.
boolean	isOfType1() Gives information about the base type of this union.
static <B,T1 extends B,T2 extends B> ObjectUnion<B,T1,T2>	newInstance1(T1 base) Constructs an ObjectUnion of type T1.
static <B,T1 extends B,T2 extends B> ObjectUnion<B,T1,T2>	newInstance2(T2 base) Constructs an ObjectUnion of type T2.
