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.
