std::experimental::weak_ptr is a modified version of std::weak_ptr that interoperates with std::experimental::shared_ptr
Member types
| Member type | Definition |
| element_type | std::remove_extent_t<T> |
Member functions
constructs new weak_ptr (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
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
|
(C++11)
|
specializes the std::swap algorithm (function template) |
