weak_ptr& operator=( const weak_ptr& r );
(1) (since C++11)
template< class Y >
weak_ptr& operator=( const weak_ptr<Y>& r );
(2) (since C++11)
template< class Y >
weak_ptr& operator=( const shared_ptr<Y>& r );
(3) (since C++11)

Replaces the managed object with the one managed by r. The object is shared with r. If r manages no object, *this manages no object too. Equivalent to weak_ptr<T>(r).swap(*this).

Notes

The implementation may meet the requirements without creating a temporary weak_ptr object.
