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 2530 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.

__submatches [IN] A list of subexpressions to return for each regular expression match within the text.
 
__m [IN] Policy flags for match rules.
