Description

This component provides a union type, UnionTestType, that supports the set of operations for a single unconstrained (value-semantic) attribute type. UnionTestType can be used during testing as the parameterized type of a class templates to ensure union types will function correctly. Note that this is particular valuable when testing a container template that supports different types of contained elements.

• data: value of this type

Usage

This section illustrates intended use of this component.

Example 1: Constructing And Using The Union

Suppose we wanted to show how objects of UnionTestType can be created and used.

UnionTestType X;
 
X.setData(-1);
assert(X.data() == -1);
 
UnionTestType Y = X;
assert(Y == X);
 
UnionTestType Z(X);
assert(Z == X);
