20.5 Class template scoped_allocator_adaptor [allocator.adaptor]

20.5.3 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;

Constraints: is_constructible_v<OuterAlloc, OuterA2> is true.

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;

Constraints: is_constructible_v<OuterAlloc, const OuterA2&> is true.

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;

Constraints: is_constructible_v<OuterAlloc, OuterA2> is true.

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