- * @class Truncate
- *
- * @brief Helper function to truncate an integral value to an int.
- *
- * Very useful since ACE methods return int very often and the value's
- * source is often a different-size integral type, such as size_t.
- * This function hides the truncation logic and resolves compiler
- * diagnostics.
- *
- * @internal Internal use only.
