Member Typedef Documentation

   template<class _T1, class _T2> typedef _T2 std::pair< _T1, _T2 >::second_type
       first_type is the first bound type

       Definition at line 91 of file stl_pair.h.

Constructor & Destructor Documentation

   template<class _T1, class _T2> constexpr std::pair< _T1, _T2 >::pair () [inline]
       second is a copy of the second object The default constructor creates first and second using their
       respective default constructors.

       Definition at line 100 of file stl_pair.h.

   template<class _T1, class _T2> constexpr std::pair< _T1, _T2 >::pair (const _T1 & __a, const _T2 & __b)
       [inline]
       Two objects may be passed to a pair constructor to be copied.

       Definition at line 104 of file stl_pair.h.

   template<class _T1, class _T2> template<class _U1 , class _U2 , class  = typename
       enable_if<__and_<is_convertible<const _U1&, _T1>,                    is_convertible<const _U2&,
       _T2>>::value>::type> constexpr std::pair< _T1, _T2 >::pair (const pair< _U1, _U2 > & __p) [inline]
       There is also a templated copy ctor for the pair class itself.
