Public Member Functions


template<typename _Del = _Dp, typename = _DeleterConstraint<_Del>> constexpr unique_ptr () noexcept
Default constructor, creates a unique_ptr that owns nothing. template<typename _Up , typename > unique_ptr (auto_ptr< _Up > &&__u) noexcept
unique_ptr (const unique_ptr &)=delete
template<typename _Del = _Dp, typename = _DeleterConstraint<_Del>> constexpr unique_ptr (nullptr_t) noexcept
Creates a unique_ptr that owns nothing. template<typename _Del = _Dp, typename = _DeleterConstraint<_Del>> unique_ptr (pointer __p) noexcept

Converting constructor from another type. ~unique_ptr () noexcept
Destructor, invokes the deleter if the stored pointer is not null. pointer get () const noexcept
Return the stored pointer. const deleter_type & get_deleter () const noexcept
Return a reference to the stored deleter. deleter_type & get_deleter () noexcept
Return a reference to the stored deleter. operator bool () const noexcept
Return true if the stored pointer is not null. add_lvalue_reference< element_type >::type operator* () const
Dereference the stored pointer. pointer operator-> () const noexcept
Return the stored pointer. unique_ptr & operator= (const unique_ptr &)=delete
unique_ptr & operator= (nullptr_t) noexcept
Reset the unique_ptr to empty, invoking the deleter if necessary. unique_ptr & operator= (unique_ptr &&)=default
Move assignment operator. template<typename _Up , typename _Ep > enable_if< __and_< __safe_conversion_up< _Up, _Ep >, is_assignable< deleter_type &, _Ep && > >::value, unique_ptr & >::type operator= (unique_ptr< _Up, _Ep > &&__u) noexcept
Assignment from another type. pointer release () noexcept
Release ownership of any stored pointer. void reset (pointer __p=pointer()) noexcept
Replace the stored pointer. void swap (unique_ptr &__u) noexcept
Exchange the pointer and deleter with another object.
(Note that these are not member functions.)
