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.

Definition at line 2574 of file regex.h.

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:

__a [IN] The start of the text to search.
__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.
