Detailed Description
template<class _T1, class _T2>
struct std::pair< _T1, _T2 >" Struct holding two objects of arbitrary type.
Template Parameters:
_T1 Type of first object.
_T2 Type of second object.
Definition at line 96 of file stl_pair.h.
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.
