Detailed Description

  template<typename _Bi_iter, typename _Ch_type = typename iterator_traits<_Bi_iter>::value_type, typename _Rx_traits = regex_traits<_Ch_type>>
class std::regex_iterator< _Bi_iter, _Ch_type, _Rx_traits >"An iterator adaptor that will provide repeated calls of regex_search over a range until no more matches remain.
