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.

using std::pair< _BiIter , _BiIter >::_PCCP = _PCC<true, _BiIter , _BiIter > [inherited]

Two objects may be passed to a pair constructor to be copied.

template<typename _BiIter > int std::sub_match< _BiIter >::compare (const string_type & __s) const [inline]

Compares this `sub_match` to a string.

Parameters

__s A string to compare to this `sub_match`.

Return values

negative This matched sequence will collate before `__s`.
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

__s Another matched sequence to compare to this one.

Return values

negative This matched sequence will collate before `__s`.
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

__s A string to compare to this `sub_match`.

Return values

negative This matched sequence will collate before `__s`.
zero This matched sequence is equivalent to `__s`.
positive This matched sequence will collate after `__s`.

template<typename _BiIter > difference_type std::sub_match< _BiIter >::length () const [inline], [noexcept]

Gets the length of the matching sequence.

References std::distance(), std::pair< _BiIter, _BiIter >::first, and std::pair< _BiIter, _BiIter >::second.

template<typename _BiIter > std::sub_match< _BiIter >::operator string_type () const [inline]

Gets the matching sequence as a string.

Returns

the matching sequence as a string.

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.

template<typename _BiIter > string_type std::sub_match< _BiIter >::str () const [inline]

Gets the matching sequence as a string.

Returns
