Detailed Description¶
template<typename _BiIter>¶
class std::sub_match< _BiIter >"A sequence of characters matched by a particular marked sub-expression.
An object of this class is essentially a pair of iterators marking a matched subexpression within a regular expression pattern match. Such objects can be converted to and compared with std::basic_string objects of a similar base character type as the pattern matched by the regular expression.
The iterators that make up the pair are the usual half-open interval referencing the actual original pattern matched.

using std::pair< _BiIter , _BiIter >::_PCCFP = _PCC<!is_same<_BiIter , _U1>::value || !is_same<_BiIter , _U2>::value, _BiIter , _BiIter > [inherited]¶
There is also a templated copy ctor for the pair class itself.

template<typename _BiIter > int std::sub_match< _BiIter >::_M_compare (const value_type * __s, size_t __n) const [inline]¶
Definition at line 942 of file regex.h.
template<typename _BiIter > int std::sub_match< _BiIter >::compare (const string_type & __s) const [inline]¶
Compares this `sub_match` to a string.
Parameters
Return values
zero This matched sequence is equivalent to `__s`.
positive This matched sequence will collate after `__s`.
Definition at line 932 of file regex.h.
template<typename _BiIter > int std::sub_match< _BiIter >::compare (const sub_match< _BiIter > & __s) const [inline]¶
Compares this and another matched sequence.
Parameters
Return values
zero This matched sequence is equivalent to `__s`.
positive This matched sequence will collate after `__s`.
Definition at line 918 of file regex.h.
template<typename _BiIter > int std::sub_match< _BiIter >::compare (const value_type * __s) const [inline]¶
Compares this `sub_match` to a string.
Parameters
Return values
zero This matched sequence is equivalent to `__s`.
positive This matched sequence will collate after `__s`.
Definition at line 936 of file regex.h.
template<typename _BiIter > difference_type std::sub_match< _BiIter >::length () const [inline], [noexcept]¶
Gets the length of the matching sequence.

template<typename _BiIter > std::sub_match< _BiIter >::operator string_type () const [inline]¶
Gets the matching sequence as a string.
Returns
This is the implicit conversion operator. It is identical to the str() member function except that it will want to pop up in unexpected places and cause a great deal of confusion and cursing from the unwary.
