Constructor & Destructor Documentation¶

template<typename _Tp, typename _Dp = default_delete<_Tp>> constexpr std::unique_ptr< _Tp, _Dp >:: unique_ptr () [inline], [noexcept]¶

Default constructor, creates a unique_ptr that owns nothing. Definition at line 157 of file unique_ptr.h.

template<typename _Tp, typename _Dp = default_delete<_Tp>> std::unique_ptr< _Tp, _Dp >:: unique_ptr (pointer__p) [inline], [explicit], [noexcept]¶

Takes ownership of a pointer. Parameters: 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) [inline], [noexcept]¶

Takes ownership of a pointer. Parameters: 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) [inline], [noexcept]¶

Takes ownership of a pointer. Parameters: 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) [inline], [noexcept]¶

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) [inline], [noexcept]¶

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) [inline], [noexcept]¶

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 () [inline], [noexcept]¶

Destructor, invokes the deleter if the stored pointer is not null. Definition at line 232 of file unique_ptr.h.
