Purpose:

Provide an attribute class to which can not be assigned.

Classes:

bsltf::NonAssignableTestType

non-assignable test type

See also:

Component bsltf_templatetestfacility

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
