std::swap
 
weak_ptr& operator=( const weak_ptr& r );
(1) (seit C++11)
template< class Y >
weak_ptr& operator=( const weak_ptr<Y>& r );
(2) (seit C++11)
template< class Y >
weak_ptr& operator=( const shared_ptr<Y>& r );
(3) (seit C++11)
Ersetzt das verwaltete Objekt mit dem von r verwaltet. Die Aufgabe wird mit r geteilt. Wenn r kein Objekt verwaltet, verwaltet *this kein Objekt zu. Entspricht weak_ptr<T>(r).swap(*this) .
Original:
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).
