Notez que les opérateurs de comparaison pour comparer simplement
shared_ptr valeurs de pointeurs, les objets réels souligné sont pas comparés. Ayant défini pour operator<shared_ptr permet shared_ptrs être utilisés comme clés dans des conteneurs associatifs, comme std::map et std::set .Original:
Note that the comparison operators for
shared_ptr simply compare pointer values; the actual objects pointed to are not compared. Having operator< defined for shared_ptr allows shared_ptrs to be used as keys in associative containers, like std::map and std::set.The text has been machine-translated via Google Translate.
