Return a shared_ptr<const ELEMENT_TYPE> that shares ownership with an existing shared_ptr object that managed this object, and throw a std::bad_weak_ptr exception if there is no shared_ptr currently managing this object. If multiple groups of shared_ptrs are managing this object, the returned shared_ptr will share ownership with the group that first managed this object.
