Detailed Description

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

Struct holding two objects of arbitrary type.

Definition at line 88 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 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.

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.
