Detailed Description

 

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

Struct holding two objects of arbitrary type.
Definition at line 87 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 90 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 99 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 103 of file stl_pair.h.

template<class _T1, class _T2> template<class _U1 , class _U2 > constexpr std::pair< _T1, _T2 >::pair (const pair< _U1, _U2 > &__p) [inline]

There is also a templated copy ctor for the pair class itself.
