std::scoped_allocator_adaptor<OuterAlloc,InnerAlloc...>::scoped_allocator_adaptor: std::scoped_allocator_adaptor<OuterAlloc,InnerAlloc...>::scoped_allocator_adaptor

NAME

std::scoped_allocator_adaptor<OuterAlloc,InnerAlloc...>::scoped_allocator_adaptor - std::scoped_allocator_adaptor<OuterAlloc,InnerAlloc...>::scoped_allocator_adaptor

Synopsis

Defined in header <scoped_allocator>
scoped_allocator_adaptor(); (1) (since C++11)
template< class OuterA2 > (2) (since C++11)
scoped_allocator_adaptor( OuterA2&& outerAlloc, const InnerAllocs&... innerAllocs) noexcept;
scoped_allocator_adaptor( const scoped_allocator_adaptor& other ) noexcept; (3) (since C++11)
scoped_allocator_adaptor( scoped_allocator_adaptor&& other ) noexcept; (4) (since C++11)
template< class OuterA2 > (5) (since C++11)
scoped_allocator_adaptor( const scoped_allocator_adaptor<OuterA2, InnerAllocs...>& other ) noexcept;
template< class OuterA2 > (6) (since C++11)
scoped_allocator_adaptor( scoped_allocator_adaptor<OuterA2, InnerAllocs...>&& other ) noexcept;

1) Default constructor: value-initializes the OuterAlloc base class and the inner allocator member object, if used by the implementation.
2) Constructs the base class OuterAlloc from std::forward<OuterA2>(outerAlloc), and the inner allocators with innerAllocs.... This overload only participates in overload resolution if std::is_constructible<OuterAlloc, OuterA2>::value is true.
3) Copy-constructor: initializes each allocator from the corresponding allocator of other
4) Move-constructor: moves each allocator from the corresponding allocator of other into *this
5) Initializes each allocator from the corresponding allocator of other. This overload only participates in overload resolution if std::is_constructible<OuterAlloc, const OuterA2&>::value is true.
6) Initializes each allocator from the corresponding allocator of other, using move semantics. This overload only participates in overload resolution if std::is_constructible<OuterAlloc, OuterA2>::value is true.

Parameters

outerAlloc - constructor argument for the outer allocator
innerAllocs... - constructor arguments for the inner allocators
other - another std::scoped_allocator_adaptor

Defect reports

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

DR Applied to Behavior as published Correct behavior
LWG_2782 C++11 constructors taking OuterA2 weren't constrained, interfering with metaprogramming constraint added
