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 2580 of file regex.h.

_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.
