- * @brief "Guard" that ensures lexer buffer switching is
- * exception-safe.
- *
- * Buffers are switched, if necessary, each time a token is
- * parsed/scanned. The buffer switching must be synchronized
- * externally. This class performs no synchronization.
- *
- * @note Note that allocation/deallocation is done once during the
- * processing of a service configurator directive. Memory
- * managements is done at a higher level, not in this class.
- * This is necessary to prevent an allocation/deallocation from
- * occurring when parsing/scanning each token.
