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.

Definition at line 272 of file stl_pair.h.

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

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

typedef _BiIter std::pair< _BiIter , _BiIter >::second_type [inherited]¶

first_type is the first bound type

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

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:

template<typename _BiIter> int std::sub_match< _BiIter >::compare (const value_type * __s) const [inline]¶

Compares this sub_match to a C-style string.

Parameters:

Return values:

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

Gets the length of the matching sequence.

Definition at line 844 of file regex.h.

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.

Definition at line 857 of file regex.h.

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

Gets the matching sequence as a string.

Returns:
