std::experi...al::weak_ptr(3) C++ Standard Libarystd::experi...al::weak_ptr(3)

NAME
       std::experimental::weak_ptr - std::experimental::weak_ptr

Synopsis
	  Defined in header <experimental/memory>
	  template< class T > class weak_ptr;	   (library fundamentals TS)

	  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 types
	  Member type  Definition
	  element_type std::remove_extent_t<T>

Member functions
	  constructor	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::experimen-
       tal::shared_ptr instead of
	  std::shared_ptr    and    std::experimental::weak_ptr	  instead   of
       std::weak_ptr. The
	  behavior is otherwise	identical.

	  destructor   destroys	a weak_ptr
		       (public member function of std::weak_ptr<T>)
	  operator=    assigns the weak_ptr
		       (public member function of std::weak_ptr<T>)

Modifiers
	  reset	       releases	the ownership of the managed object
		       (public member function of std::weak_ptr<T>)
	  swap	       swaps the managed objects
		       (public member function of std::weak_ptr<T>)

Observers
	  use_count    returns the number of shared_ptr	 objects  that	manage
       the object
		       (public member function of std::weak_ptr<T>)
	  expired	checks	whether	 the  referenced  object  was  already
       deleted
		       (public member function of std::weak_ptr<T>)
	  lock	       creates a shared_ptr that manages the referenced	object
		       (public member function of std::weak_ptr<T>)
	  owner_before 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	 name-
       space, and work
	  with std::experimental::weak_ptr rather than std::weak_ptr, but oth-
       erwise behaves
	  identically to the corresponding C++14 function.

	  std::swap(std::weak_ptr) specializes the std::swap algorithm
	  (C++11)		   (function template)
