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

constructs new weak_ptr (public member function) [edit]

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> ) [edit]
|
|
assigns the weak_ptr (public member function of std::weak_ptr<T> ) [edit]
|
Modifiers
|
|
releases the ownership of the managed object (public member function of std::weak_ptr<T> ) [edit]
|
|
swaps the managed objects (public member function of std::weak_ptr<T> ) [edit]
|
Observers
|
|
returns the number of shared_ptr objects that manage the object (public member function of std::weak_ptr<T> ) [edit]
|
|
checks whether the referenced object was already deleted (public member function of std::weak_ptr<T> ) [edit]
|
|
creates a shared_ptr that manages the referenced object (public member function of std::weak_ptr<T> ) [edit]
|
|
provides owner-based ordering of weak pointers (public member function of std::weak_ptr<T> ) [edit]
|
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.
