typename conditional< is_reference< deleter_type >::value, deleter_type, const deleter_type &>::type  __d 
)
inlinenoexcept

Takes ownership of a pointer.

Parameters
__pA pointer to an array of a type safely convertible to an array of element_type
__dA reference to a deleter.

The deleter will be initialized with __d

Definition at line 485 of file unique_ptr.h.

◆ unique_ptr() [4/6]

template<typename _Tp , typename _Dp >
template<typename _Up , typename = typename enable_if< __safe_conversion_raw<_Up>::value, bool>::type>
std::unique_ptr< _Tp[], _Dp >::unique_ptr ( _Up  __p,
typename remove_reference< deleter_type >::type &&  __d 
)
inlinenoexcept

Takes ownership of a pointer.

Parameters
__pA pointer to an array of a type safely convertible to an array of element_type
__dA reference to a deleter.

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

Definition at line 501 of file unique_ptr.h.

◆ unique_ptr() [5/6]

template<typename _Tp , typename _Dp >
std::unique_ptr< _Tp[], _Dp >::unique_ptr ( unique_ptr< _Tp[], _Dp > &&  __u)
inlinenoexcept

Move constructor.

Definition at line 508 of file unique_ptr.h.

◆ unique_ptr() [6/6]

template<typename _Tp , typename _Dp >
template<typename _Up = _Dp, typename = _DeleterConstraint<_Up>>
constexpr std::unique_ptr< _Tp[], _Dp >::unique_ptr ( nullptr_t  )
inlinenoexcept

Creates a unique_ptr that owns nothing.

Definition at line 514 of file unique_ptr.h.

◆ ~unique_ptr()

template<typename _Tp , typename _Dp >
std::unique_ptr< _Tp[], _Dp >::~unique_ptr ( )
inline

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

◆ get_deleter() [1/2]

template<typename _Tp , typename _Dp >
deleter_type& std::unique_ptr< _Tp[], _Dp >::get_deleter ( )
inlinenoexcept

Return a reference to the stored deleter.

Definition at line 592 of file unique_ptr.h.

◆ get_deleter() [2/2]

template<typename _Tp , typename _Dp >
const deleter_type& std::unique_ptr< _Tp[], _Dp >::get_deleter ( ) const

template<typename _Tp , typename _Dp >
unique_ptr& std::unique_ptr< _Tp[], _Dp >::operator= ( unique_ptr< _Tp[], _Dp > &&  __u)
inlinenoexcept

Move assignment operator.

Parameters
__uThe object to transfer ownership from.

Invokes the deleter first if this object owns a pointer.

References std::get_deleter().

◆ operator=() [2/3]

template<typename _Tp , typename _Dp >
template<typename _Up , typename _Ep >

inlinenoexcept

Assignment from another type.

Parameters
__uThe object to transfer ownership from, which owns a convertible pointer to an array object.

Invokes the deleter first if this object owns a pointer.

Definition at line 560 of file unique_ptr.h.
