522 * @brief A specialization of vector for booleans which offers fixed time
523 * access to individual elements in any order.
527 * @tparam _Alloc Allocator type.
529 * Note that vector<bool> does not actually meet the requirements for being
530 * a container. This is because the reference and pointer types are not
531 * really references and pointers to bool. See DR96 for details. @see
532 * vector for function documentation.
534 * In some terminology a %vector can be described as a dynamic
535 * C-style array, it offers fast and efficient access to individual
536 * elements in any order and saves the user from worrying about
537 * memory and size allocation. Subscripting ( @c [] ) access is
538 * also provided as with C-style arrays.
