Defined in header <scoped_allocator>
template< class OuterAlloc, class... InnerAlloc >
class scoped_allocator_adaptor : public OuterAlloc;
 (ya que C + +11)
La plantilla de clase std::scoped_allocator_adaptor es un asignador de que puede ser usado con recipientes de varios niveles (vector de conjuntos de listas de tuplas de mapas, etc.) Se crea una instancia de un tipo asignador OuterAlloc exterior y cero o más InnerAlloc... interior asignador de tipos. Un recipiente construido directamente con un scoped_allocator_adaptor OuterAlloc utiliza para asignar sus elementos, pero si un elemento en sí es un contenedor, se utiliza el asignador interior primero. Los elementos de ese contenedor, si ellos mismos son contenedores, utilizar el asignador segundo interior, etc Si hay más niveles en el recipiente que hay asignadores de interiores, se reutiliza el asignador interior pasado para todos los contenedores anidados más .
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.

Para el propósito de scoped_allocator_adaptor, si el asignador interior siguiente es A, cualquier T clase para la que std::uses_allocator<T,A>::value == true participa en la recursividad como si fuera un recipiente. Además, std::pair es tratado como tal recipiente por sobrecargas concretas 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.
