20.13 Class template scoped_allocator_adaptor [allocator.adaptor]

20.13.3 Scoped allocator adaptor constructors [allocator.adaptor.cnstr]

scoped_allocator_adaptor();

Effects: value-initializes the OuterAlloc base class and the inner allocator object.

template <class OuterA2> scoped_allocator_adaptor(OuterA2&& outerAlloc, const InnerAllocs&... innerAllocs) noexcept;

Requires: OuterAlloc shall be constructible from OuterA2.

Effects: initializes the OuterAlloc base class with std::forward<OuterA2>(outerAlloc) and inner with innerAllocs... (hence recursively initializing each allocator within the adaptor with the corresponding allocator from the argument list).

scoped_allocator_adaptor(const scoped_allocator_adaptor& other) noexcept;

Effects: initializes each allocator within the adaptor with the corresponding allocator from other.

scoped_allocator_adaptor(scoped_allocator_adaptor&& other) noexcept;

Effects: move constructs each allocator within the adaptor with the corresponding allocator from other.

template <class OuterA2> scoped_allocator_adaptor(const scoped_allocator_adaptor<OuterA2, InnerAllocs...>& other) noexcept;

Requires: OuterAlloc shall be constructible from OuterA2.

Effects: initializes each allocator within the adaptor with the corresponding allocator from other.

template <class OuterA2> scoped_allocator_adaptor(scoped_allocator_adaptor<OuterA2, InnerAllocs...>&& other) noexcept;

Requires: OuterAlloc shall be constructible from OuterA2.

Effects: initializes each allocator within the adaptor with the corresponding allocator rvalue from other.
