Detailed Description

Function Documentation

template<typename _Tp >
_Tp* std::__addressof ( _Tp &  __r)
inlinenoexcept
template<typename _Tp >
_Tp* std::addressof ( _Tp &  __r)
inlinenoexcept

Returns the actual address of the object or function referenced by r, even in the presence of an overloaded operator&.

Parameters
__rReference to an object or function.
Returns
The actual address.

Definition at line 135 of file move.h.

References std::__addressof().

Referenced by std::pointer_traits< _Tp * >::pointer_to().

template<typename _Tp >
constexpr _Tp&& std::forward ( typename std::remove_reference< _Tp >::type &  __t)
noexcept

Forward an lvalue.

Returns
The parameter cast to the specified type.

This function is used to implement "perfect forwarding".

Definition at line 76 of file move.h.

template<typename _Tp >
constexpr _Tp&& std::forward ( typename std::remove_reference< _Tp >::type &&  __t)
noexcept

Forward an rvalue.

Returns
The parameter cast to the specified type.

This function is used to implement "perfect forwarding".

Definition at line 87 of file move.h.

template<class _T1 , class _T2 >
constexpr pair<typename __decay_and_strip<_T1>::__type, typename __decay_and_strip<_T2>::__type> std::make_pair ( _T1 &&  __x,
_T2 &&  __y 
)
template<typename _Tp >
constexpr conditional<__move_if_noexcept_cond<_Tp>::value, const _Tp&, _Tp&&>::type std::move_if_noexcept ( _Tp &  __x)
noexcept

Conditionally convert a value to an rvalue.

Parameters
__xA thing of arbitrary type.
Returns
The parameter, possibly cast to an rvalue-reference.

Same as std::move unless the type's move constructor could throw and the type is copyable, in which case an lvalue-reference is returned instead.

Definition at line 121 of file move.h.

References std::move().

template<class _T1 , class _T2 >
constexpr bool std::operator!= ( const pair< _T1, _T2 > &  __x,
const pair< _T1, _T2 > &  __y 
)
inline

Uses operator== to find the result.

Definition at line 227 of file stl_pair.h.

template<class _T1 , class _T2 >
constexpr bool std::operator< ( const pair< _T1, _T2 > &  __x,
const pair< _T1, _T2 > &  __y

template<class _T1 , class _T2 >
constexpr bool std::operator<= ( const pair< _T1, _T2 > &  __x,
const pair< _T1, _T2 > &  __y 
)
inline

Uses operator< to find the result.

Definition at line 239 of file stl_pair.h.

template<class _T1 , class _T2 >
constexpr bool std::operator== ( const pair< _T1, _T2 > &  __x,
const pair< _T1, _T2 > &  __y 
)
inline

Two pairs of the same type are equal iff their members are equal.

template<typename _Tp , size_t _Nm>
void std::swap ( _Tp(&)  __a[_Nm],
_Tp(&)  __b[_Nm]
