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:
__p A pointer to an object of element_type
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:
__p A pointer to an object of element_type
__d A reference to a deleter.
The deleter will be initialized with __d
Definition at line 184 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:
__p A pointer to an object of element_type
__d An rvalue reference to a deleter.
The deleter will be initialized with std::move(__d)
Definition at line 196 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 203 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 208 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 223 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 235 of file unique_ptr.h.

(unique_ptr< _Tp, _Dp > && __u) [inline], [noexcept]
Move assignment operator.
Parameters:
__u The object to transfer ownership from.
Invokes the deleter first if this object owns a pointer.
Definition at line 252 of file unique_ptr.h.
template<typename _Tp, typename _Dp = default_delete<_Tp>> template<typename _Up , typename _Ep > enable_if<

Parameters:
__u The object to transfer ownership from, which owns a convertible pointer to a non-array object.
