Detailed Description

Function Documentation

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

Same as C++11 std::addressof.

Definition at line 47 of file move.h.

Referenced by std::_Destroy(), std::addressof(), __gnu_debug::_Safe_local_iterator< _Iterator, _Sequence >::operator->(), and __gnu_debug::_Safe_iterator< _Iterator, _Sequence >::operator->().

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 
)

A convenience wrapper for creating a pair from two objects.

Parameters
__xThe first object.
__yThe second object.
Returns
A newly-constructed pair<> object of the appropriate type.

The standard requires that the objects be passed by reference-to-const, but LWG issue #181 says they should be passed by const value. We follow the LWG by default.

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

Convert a value to an rvalue.

Parameters
__tA thing of arbitrary type.
Returns
The parameter cast to an rvalue-reference to allow moving it.

Definition at line 101 of file move.h.

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.
