Elemento definito nell'header <scoped_allocator>
template<class OuterAlloc, class... InnerAlloc> class scoped_allocator_adaptor :public OuterAlloc;		(dal C++11)

Il modello di classe std::scoped_allocator_adaptor è un allocatore che possono essere utilizzati per i contenitori più livelli (vettore di insiemi di liste di tuple di mappe, ecc.) E 'un'istanza con un OuterAlloc esterno tipo allocatore e zero o più interiore InnerAlloc... allocatore tipi. Un contenitore costruito direttamente con un scoped_allocator_adaptorOuterAlloc utilizza per allocare suoi elementi, ma se un elemento è esso stesso un contenitore, utilizza l'allocatore primo interna. Gli elementi di tale contenitore, se essi stessi sono contenitori, utilizzare l'allocatore secondo interno, ecc Se ci sono più livelli per il contenitore che ci sono ripartitori interni, viene riutilizzato l'allocatore ultimo interno per tutti i contenitori ulteriori nidificati.

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.

Ai fini della scoped_allocator_adaptor, se l'allocatore prossima interno è A, qualsiasi T classe per cui std::uses_allocator<T,A>::value==true partecipa alla ricorsione come se fosse un contenitore. Inoltre, std::pair è trattata come un contenitore da sovraccarichi specifici di 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.
