Purpose:

Provide an attribute class that is not equal comparable.

Classes:

bsltf::NonEqualComparableTestType

non-equal-comparable class

Component bsltf_templatetestfacility

Description:

This component provides a single, unconstrained (value-semantic) attribute class, NonEqualComparableTestType, that does not provide equality-comparison operators. This is particularly valuable when test containers that should work with non-equal-comparable 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 Equality Compared:

Suppose we wanted to show NonEqualComparableTestType can't be equal compared.

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

  NonEqualComparableTestType X(1);
  NonEqualComparableTestType Y(2);

Now, we show that equal comparing X and Y will not compile:

  assert(X != Y); // This will not compile
