std::experimental::weak_ptr
is a modified version of
std::weak_ptr
that interoperates with
std::experimental::shared_ptr
and has support for arrays.

Member functions
constructs new

(public member function) |
Members and non-members identical to std:: weak_ptr
Member functions
The following member functions work with std::experimental::shared_ptr instead of std::shared_ptr and std::experimental::weak_ptr instead of std::weak_ptr . The behavior is otherwise identical.
destroys a
weak_ptr
(public member function of
std::weak_ptr<T>
)
|
|
assigns the
weak_ptr
(public member function of
std::weak_ptr<T>
)
|
|
Modifiers |
|
|
releases the ownership of the managed object
(public member function of
std::weak_ptr<T>
)
|
|
|
swaps the managed objects
(public member function of
std::weak_ptr<T>
)
|
|
Observers |
|
returns the number of
shared_ptr
objects that manage the object
(public member function of
std::weak_ptr<T>
)
|
|
|
checks whether the referenced object was already deleted
(public member function of
std::weak_ptr<T>
)
|
|
creates a
shared_ptr
that manages the referenced object
(public member function of
std::weak_ptr<T>
)
|
|
|
provides owner-based ordering of weak pointers
(public member function of
std::weak_ptr<T>
)
|
|
Non-member functions
This non-member function is declared in the
std::experimental
namespace, and work with
std::experimental::weak_ptr
rather than
std::weak_ptr
, but otherwise behaves identically to the corresponding C++14 function.

(C++11)

algorithm
