Detailed Description

template<typename BidirIt, typename CharT = typename std::iterator_traits<BidirIt>::value_type, typename Traits = std::regex_traits<CharT>>
class real::compat::regex_iterator< BidirIt, CharT, Traits >

Iterates the non-overlapping matches of a pattern in a sequence (std::regex_iterator).

Same per-operation routing as regex_replace — a real-backed, non-nullable pattern drives real's linear traversal (repeated region search — a non-nullable pattern never matches empty, so the position always advances past the match and the ECMAScript and real sequences agree); the std backend and nullable patterns wrap std::regex_iterator (whose empty-match advance is ECMAScript's). The default-constructed iterator is the end sentinel.

Template Parameters

BidirIt A contiguous iterator into the searched sequence.
