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
template<typename _Del  = deleter_type, typename  = _Require<is_move_constructible<_Del>>> unique_ptr (pointer __p, __enable_if_t<!is_lvalue_reference< _Del >::value, _Del && > __d) noexcept
template<typename _Del  = deleter_type, typename  = _Require<is_copy_constructible<_Del>>> unique_ptr (pointer __p, const deleter_type &__d) noexcept
template<typename _Del  = deleter_type, typename _DelUnref  = typename remove_reference<_Del>::type> unique_ptr (pointer, __enable_if_t< is_lvalue_reference< _Del >::value, _DelUnref && >)=delete
unique_ptr (unique_ptr &&)=default
Move constructor.
template<typename _Up , typename _Ep , typename  = _Require<               __safe_conversion_up<_Up, _Ep>,       typename conditional<is_reference<_Dp>::value,    is_same<_Ep, _Dp>,    is_convertible<_Ep, _Dp>>::type>> unique_ptr (unique_ptr< _Up, _Ep > &&__u) 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.
