class std::unique_ptr< _Tp, _Dp >"A move-only smart pointer that manages unique ownership of a resource.

Since

C++11

Default constructor, creates a unique_ptr that owns nothing.

Takes ownership of a pointer.

Parameters

The deleter will be value-initialized.

Takes ownership of a pointer.

Parameters

The deleter will be initialized with __d

Takes ownership of a pointer.

Parameters

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

Creates a unique_ptr that owns nothing.

Move constructor.

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.

Converting constructor from auto_ptr.

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

References std::unique_ptr< _Tp, _Dp >::get_deleter(), and std::move().

Return the stored pointer.

Referenced by std::unique_ptr< _Tp, _Dp >::operator bool(), std::unique_ptr< _Tp, _Dp >::operator*(), and std::unique_ptr< _Tp, _Dp >::operator->().

Return a reference to the stored deleter.

Return a reference to the stored deleter.

Referenced by std::unique_ptr< _Tp, _Dp >::~unique_ptr(), and std::unique_ptr< _Tp, _Dp >::operator=().

Return true if the stored pointer is not null.

References std::unique_ptr< _Tp, _Dp >::get().

Dereference the stored pointer.

References std::unique_ptr< _Tp, _Dp >::get().

Return the stored pointer.

References std::unique_ptr< _Tp, _Dp >::get().

Reset the unique_ptr to empty, invoking the deleter if necessary.

References std::unique_ptr< _Tp, _Dp >::reset().

Move assignment operator. Invokes the deleter if this object owns a pointer.

Assignment from another type.

Parameters

Invokes the deleter if this object owns a pointer.

References std::unique_ptr< _Tp, _Dp >::get_deleter(), and std::unique_ptr< _Tp, _Dp >::reset().

Release ownership of any stored pointer.

Replace the stored pointer.

Parameters

The deleter will be invoked if a pointer is already owned.

References std::move().

Referenced by std::unique_ptr< _Tp, _Dp >::operator=(), and std::unique_ptr< _Tp, _Dp >::operator=().

Exchange the pointer and deleter with another object.
