    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).
