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.

Constructs a regex_iterator...

Parameters
__a[IN] The start of a text range to search.
__b[IN] One-past-the-end of the text range to search.
__re[IN] The regular expression to match.
__m[IN] Policy flags for match rules.
