Detailed Description

template<class _T1, class _T2>
struct std::pair< _T1, _T2 >

Struct holding two objects of arbitrary type.

Template Parameters:
_T1Type of first object.
_T2Type of second object.

Member Typedef Documentation

template<class _T1, class _T2>
typedef _T2 std::pair< _T1, _T2 >::second_type

first_type is the first bound type

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 _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.
