weak_ptr& operator=( const weak_ptr& r );

template< class Y >

(2) (depuis C++11)
template< class Y >
weak_ptr& operator=( const shared_ptr<Y>& r );
(3) (depuis C++11)
Remplace l'objet géré avec celui géré par r. L'objet est partagé avec r. Si r gère aucun objet, aucun objet *this gère aussi. Equivalent à 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).
