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.

Attributes:

  Name                Type         Default
  ------------------  -----------  -------
  data                int          0

• 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);
