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_token_iterator< _Bi_iter, _Ch_type, _Rx_traits >"Iterates over submatches in a range (or splits a text string).
The purpose of this iterator is to enumerate all, or all specified, matches of a regular expression within a text range. The dereferenced value of an iterator of this class is a std::sub_match object.

Constructor & Destructor Documentation¶
template<typename _Bi_iter , typename _Ch_type = typename iterator_traits<_Bi_iter>::value_type, typename _Rx_traits = regex_traits<_Ch_type>> std::regex_token_iterator< _Bi_iter, _Ch_type, _Rx_traits >::regex_token_iterator () [inline]¶
Default constructs a regex_token_iterator. A default-constructed regex_token_iterator is a singular iterator that will compare equal to the one-past-the-end value for any iterator of the same type.
template<typename _Bi_iter , typename _Ch_type = typename iterator_traits<_Bi_iter>::value_type, typename _Rx_traits = regex_traits<_Ch_type>> std::regex_token_iterator< _Bi_iter, _Ch_type, _Rx_traits >::regex_token_iterator (_Bi_iter __a, _Bi_iter __b, const regex_type & __re, int __submatch = 0, regex_constants::match_flag_type __m = regex_constants::match_default) [inline]¶
Constructs a regex_token_iterator...
Parameters
__b [IN] One-past-the-end of the text to search.
__re [IN] The regular expression to search for.
__submatch [IN] Which submatch to return. There are some special values for this parameter:
- -1 each enumerated subexpression does NOT match the regular expression (aka field splitting)
- 0 the entire string matching the subexpression is returned for each match within the text.
- >0 enumerates only the indicated subexpression from a match within the text.
__m [IN] Policy flags for match rules.
template<typename _Bi_iter , typename _Ch_type = typename iterator_traits<_Bi_iter>::value_type, typename _Rx_traits = regex_traits<_Ch_type>> std::regex_token_iterator< _Bi_iter, _Ch_type, _Rx_traits >::regex_token_iterator (_Bi_iter __a, _Bi_iter __b, const regex_type & __re, const std::vector< int > & __submatches, regex_constants::match_flag_type __m = regex_constants::match_default) [inline]¶
Constructs a regex_token_iterator...
Parameters
__b [IN] One-past-the-end of the text to search.
__re [IN] The regular expression to search for.
__submatches [IN] A list of subexpressions to return for each regular expression match within the text.
__m [IN] Policy flags for match rules.
template<typename _Bi_iter , typename _Ch_type = typename iterator_traits<_Bi_iter>::value_type, typename _Rx_traits = regex_traits<_Ch_type>> std::regex_token_iterator< _Bi_iter, _Ch_type, _Rx_traits >::regex_token_iterator (_Bi_iter __a, _Bi_iter __b, const regex_type & __re, initializer_list< int > __submatches, regex_constants::match_flag_type __m = regex_constants::match_default) [inline]¶
Constructs a regex_token_iterator...
Parameters
__b [IN] One-past-the-end of the text to search.
__re [IN] The regular expression to search for.
__submatches [IN] A list of subexpressions to return for each regular expression match within the text.
__m [IN] Policy flags for match rules.
template<typename _Bi_iter , typename _Ch_type = typename iterator_traits<_Bi_iter>::value_type, typename _Rx_traits = regex_traits<_Ch_type>> template<std::size_t _Nm> std::regex_token_iterator< _Bi_iter, _Ch_type, _Rx_traits >::regex_token_iterator (_Bi_iter __a, _Bi_iter __b, const regex_type & __re, const int(&) __submatches[_Nm], regex_constants::match_flag_type __m = regex_constants::match_default) [inline]¶
Constructs a regex_token_iterator...
Parameters
__b [IN] One-past-the-end of the text to search.
__re [IN] The regular expression to search for.
__submatches [IN] A list of subexpressions to return for each regular expression match within the text.
__m [IN] Policy flags for match rules.
template<typename _Bi_iter , typename _Ch_type = typename iterator_traits<_Bi_iter>::value_type, typename _Rx_traits = regex_traits<_Ch_type>> std::regex_token_iterator< _Bi_iter, _Ch_type, _Rx_traits >::regex_token_iterator (const regex_token_iterator< _Bi_iter, _Ch_type, _Rx_traits > & __rhs) [inline]¶
Copy constructs a regex_token_iterator.
