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
__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.
