Description

This component provides a single, unconstrained (value-semantic) attribute class, NonAssignableTestType, that does not not support assignment. This is particularly valuable when testing container operations that works with non-assignable types.

Attributes

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

• data: representation of the class value

Usage

This section illustrates intended use of this component.

Example 1: Demonstrating The Type Cannot Be Assigned To

Suppose we wanted to show NonAssignableTestType can't be assigned to:

First, we create two NonAssignableTestType objects, X and Y:

NonAssignableTestType X(1);
NonAssignableTestType Y(2);

Now, we show that assigning X from Y will not compile:

X = Y; // This will not compile
