20.7.1.2 unique_ptr for single objects.

Definition at line 129 of file unique_ptr.h.

Constructor & Destructor Documentation

template<typename _Tp, typename _Dp = default_delete<_Tp>>

constexpr std::unique_ptr< _Tp, _Dp >::unique_ptr ( )

inlinenoexcept

Default constructor, creates a unique_ptr that owns nothing.

Definition at line 157 of file unique_ptr.h.

Referenced by std::auto_ptr< _Tp >::auto_ptr().

template<typename _Tp, typename _Dp = default_delete<_Tp>>

std::unique_ptr< _Tp, _Dp >::unique_ptr ( pointer  __p )

inlineexplicitnoexcept

Takes ownership of a pointer.

Parameters

__p	A pointer to an object of element_type

The deleter will be value-initialized.

Definition at line 169 of file unique_ptr.h.

template<typename _Tp, typename _Dp = default_delete<_Tp>>

std::unique_ptr< _Tp, _Dp >::unique_ptr ( pointer  __p, typename conditional< is_reference< deleter_type >::value, deleter_type, const deleter_type & >::type  __d  )

inlinenoexcept

Takes ownership of a pointer.

Parameters

__p	A pointer to an object of element_type
__d	A reference to a deleter.

The deleter will be initialized with __d

Definition at line 181 of file unique_ptr.h.

template<typename _Tp, typename _Dp = default_delete<_Tp>>

std::unique_ptr< _Tp, _Dp >::unique_ptr ( pointer  __p, typename remove_reference< deleter_type >::type &&  __d  )

inlinenoexcept

Takes ownership of a pointer.

Parameters

__p	A pointer to an object of element_type
__d	An rvalue reference to a deleter.

The deleter will be initialized with std::move(__d)

Definition at line 193 of file unique_ptr.h.

template<typename _Tp, typename _Dp = default_delete<_Tp>>

constexpr std::unique_ptr< _Tp, _Dp >::unique_ptr ( nullptr_t  )

inlinenoexcept

Creates a unique_ptr that owns nothing.

Definition at line 200 of file unique_ptr.h.

template<typename _Tp, typename _Dp = default_delete<_Tp>>

std::unique_ptr< _Tp, _Dp >::unique_ptr ( unique_ptr< _Tp, _Dp > &&  __u )

inlinenoexcept

Move constructor.

Definition at line 205 of file unique_ptr.h.

template<typename _Tp, typename _Dp = default_delete<_Tp>>

template<typename _Up , typename _Ep , typename = _Require< is_convertible<typename unique_ptr<_Up, _Ep>::pointer, pointer>, __not_<is_array<_Up>>, typename conditional<is_reference<_Dp>::value, is_same<_Ep, _Dp>, is_convertible<_Ep, _Dp>>::type>>

std::unique_ptr< _Tp, _Dp >::unique_ptr ( unique_ptr< _Up, _Ep > &&  __u )

inlinenoexcept

Converting constructor from another type.

Requires that the pointer owned by __u is convertible to the type of pointer owned by this object, __u does not own an array, and __u has a compatible deleter type.

Definition at line 220 of file unique_ptr.h.

template<typename _Tp, typename _Dp = default_delete<_Tp>>

std::unique_ptr< _Tp, _Dp >::~unique_ptr ( )

inlinenoexcept

Destructor, invokes the deleter if the stored pointer is not null.

Definition at line 232 of file unique_ptr.h.

unique_ptr& std::unique_ptr< _Tp, _Dp >::operator= ( unique_ptr< _Tp, _Dp > &&  __u )

inlinenoexcept

Move assignment operator.

Parameters
