Detailed Description

Components deemed generally useful. Includes pair, tuple, forward/move helpers, ratio, function object, metaprogramming and type traits, time, date, and memory functions.

Function Documentation

template<typename _Tp >

_Tp* std::__addressof ( _Tp &  __r )

inline

Same as C++11 std::addressof.

Definition at line 47 of file move.h.

Referenced by std::addressof(), std::begin(), std::vector< _State >::data(), std::end(), std::forward_list< _Tp, _Alloc >::remove(), and std::list< _Tp, _Alloc >::remove().

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

__r	Reference to an object or function.

Returns

The actual address.

Definition at line 136 of file move.h.

References std::__addressof().

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

template<typename _Tp >

add_rvalue_reference< _Tp >::type std::declval ( )

inlinenoexcept

Utility to simplify expressions used in unevaluated operands.

Definition at line 1774 of file type_traits.

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 77 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 88 of file move.h.

template<typename _Tp >

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

noexcept

Convert a value to an rvalue.

Parameters

__t	A thing of arbitrary type.

Returns

The parameter cast to an rvalue-reference to allow moving it.

Definition at line 102 of file move.h.

template<typename _Tp >

conditional<__move_if_noexcept_cond<_Tp>::value, const _Tp&, _Tp&&>::type std::move_if_noexcept ( _Tp &  __x )

inlinenoexcept

Conditionally convert a value to an rvalue.

Parameters

__x	A 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 122 of file move.h.

template<typename _Tp >

void std::swap ( _Tp &  __a, _Tp &  __b  ) const

inlinenoexcept

Swaps two values.

Parameters

__a	A thing of arbitrary type.
__b	Another thing of arbitrary type.

Returns

Nothing.

Definition at line 167 of file move.h.

template<typename _Tp , size_t _Nm>

void std::swap ( _Tp(&)  __a[_Nm], _Tp(&)  __b[_Nm]  )

inlinenoexcept

Swap the contents of two arrays.

Definition at line 186 of file move.h.
