    template< class OuterAlloc, class... InnerAlloc > class scoped_allocator_adaptor : public OuterAlloc;
    		 (depuis C++11)
    Le modèle de classe std::scoped_allocator_adaptor est un allocateur qui peut être utilisé avec des conteneurs à plusieurs niveaux (vecteur d'ensembles de listes de tuples de cartes, etc.) Il est instancié avec une OuterAlloc allocateur de type externe et zéro ou plusieurs types d'affectation interne InnerAlloc.... Un conteneur construit directement avec un scoped_allocator_adaptor utilise OuterAlloc d'allouer ses éléments, mais si un élément est lui-même un conteneur, il utilise l'allocateur intérieure de la première. Les éléments de ce conteneur, si elles sont elles-mêmes conteneurs, utiliser l'allocateur secondes intérieure, etc S'il ya plus de niveaux pour le récipient supérieur au nombre de répartiteurs d'air, l'allocateur dernier intérieure est réutilisée pour tous les autres récipients emboîtés .
    Original:
    The std::scoped_allocator_adaptor class template is an allocator which can be used with multilevel containers (vector of sets of lists of tuples of maps, etc). It is instantiated with one outer allocator type OuterAlloc and zero or more inner allocator types InnerAlloc.... A container constructed directly with a scoped_allocator_adaptor uses OuterAlloc to allocate its elements, but if an element is itself a container, it uses the first inner allocator. The elements of that container, if they are themselves containers, use the second inner allocator, etc. If there are more levels to the container than there are inner allocators, the last inner allocator is reused for all further nested containers.

    Dans le but de scoped_allocator_adaptor, si le dispositif d'attribution interne suivante est A, tout T classe pour laquelle std::uses_allocator<T,A>::value == true participe à la récurrence comme s'il s'agissait d'un conteneur. En outre, std::pair est traité comme tel récipient par des surcharges spécifiques de scoped_allocator_adaptor::construct .
    Original:
    For the purpose of scoped_allocator_adaptor, if the next inner allocator is A, any class T for which std::uses_allocator<T,A>::value == true participates in the recursion as if it was a container. Additionally, std::pair is treated as such a container by specific overloads of scoped_allocator_adaptor::construct.
