Purpose:

Provide an enumeration of move-state, including unsupported.

Classes:

bsltf::MoveState

namespace for move-state enumeration

Description:

This component provides a struct, bsltf_MoveState, which serves as a namespace for enumerating the move-state of an object, including an unknown value indicating that the test type does not support tracking of this information. An object is involved in a move operation if that object was either the source or target of a move construction or move assignment. It's up to the test type to support moved-into or moved-from or both using separate instances of this enum.

Enumerators:

  Name          Description
  -----------   -------------------------------------------------------------
  e_NOT_MOVED   The type was not involved in a move operation.

  e_MOVED       The type was involved in a move operation.

  e_UNKNOWN     The type does not expose move-state infromation.

Usage:

This section illustrates intended use of this component.

Example 1: Basic Syntax:

The following snippets of code provide a simple illustration of using bsltf::MoveState.

First, we create a variable value of type bsltf::MoveState::Enum and initialize it with the enumerator value bsltf::MoveState::e_MOVED:

  bsltf::MoveState::Enum value = bsltf::MoveState::e_MOVED;

Now, we store the address of its ASCII representation in a pointer variable, asciiValue, of type const char *:

  const char *asciiValue = bsltf::MoveState::toAscii(value);

Finally, we verify the value of asciiValue:

  assert(0 == strcmp(asciiValue, "MOVED"));
