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 99 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 108 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 112 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. Definition at line 124 of file stl_pair.h.
