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.
