class scoped_allocator_adaptor : public OuterAlloc;
 (начиная с C++11)
Шаблон std::scoped_allocator_adaptor класса распределитель, который можно использовать с многоуровневой контейнеров (вектор множества списков наборов карт и т.д.). Он создается с одним внешним OuterAlloc тип распределителя и ноль или более внутренних распределитель типа InnerAlloc.... Контейнер построен непосредственно с scoped_allocator_adaptor использует OuterAlloc выделить его элементы, но если элемент сам по себе является контейнером, он использует первый внутренний распределитель. Элементы этого контейнера, если они сами контейнеры, используйте второй внутренний распределитель, и т.д. Если есть больше уровней в контейнере, чем есть внутренние распределители, последний внутренний распределитель повторно используется для всех последующих вложенных контейнеров.
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.

Для scoped_allocator_adaptor, если следующий внутренний распределитель является A, любой класс T, для которых std::uses_allocator<T,A>::value == true участвует в рекурсию, как если бы это был контейнер. Кроме того, std::pair рассматривается как такой контейнер конкретных перегрузок 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.
