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< sub_match< _Bi_iter >, allocator< sub_match< _Bi_iter > > >::data(), std::end(), std::forward_list< _Tp, _Alloc >::remove(), and std::list< _Tp, _Alloc >::remove().

template<typename _Tp >

_Tp* std::addressof

(

_Tp &

__r

)

[inline]

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

(

)

[inline]

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

)

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

)

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

)

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

)

[inline]

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 [inline]

Swaps two values.

Parameters:

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

Returns:

Nothing.

template<typename _Tp , size_t _Nm>

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

Swap the contents of two arrays.
