std::scoped...ator_adaptor(3) C++ Standard Libarystd::scoped...ator_adaptor(3)

NAME
       std::scoped_allocator_adaptor::scoped_allocator_adaptor		     -
       std::scoped_allocator_adaptor::scoped_allocator_adaptor

Synopsis
	  Defined in header <scoped_allocator>
	  scoped_allocator_adaptor();
       (1) (since C++11)
	  template< class OuterA2 >
	  scoped_allocator_adaptor(	 OuterA2&&	outerAlloc,	 const
       (2) (since C++11)
	  InnerAllocs&... innerAllocs) noexcept;
	  scoped_allocator_adaptor(  const  scoped_allocator_adaptor&  other )
       (3) (since C++11)
	  noexcept;
	  scoped_allocator_adaptor(   scoped_allocator_adaptor&&    other    )
       (4) (since C++11)
	  noexcept;
	  template< class OuterA2 >
	  scoped_allocator_adaptor(   const  scoped_allocator_adaptor<OuterA2,
       (5) (since C++11)
	  InnerAllocs...>& other ) noexcept;
	  template< class OuterA2 >
	  scoped_allocator_adaptor(	     scoped_allocator_adaptor<OuterA2,
       (6) (since C++11)
	  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<Out-
       erA2>(outerAlloc), and
	  the inner allocators with innerAllocs.... This overload participates
       in overload
	  resolution only if std::is_constructible<OuterAlloc, OuterA2>::value
       is true.
	  3) Copy-constructor: initializes each	allocator from the correspond-
       ing allocator of
	  other
	  4) Move-constructor: moves each allocator from the corresponding al-
       locator of other
	  into *this
	  5)  Initializes  each	 allocator from	the corresponding allocator of
       other. This
	  overload participates	in overload resolution only 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 participates	in overload resolution only 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 retroac-
       tively to
	  previously published C++ standards.

	     DR	      Applied	 to		    Behavior	as   published
       Correct behavior
	  LWG	2782   C++11	    constructors   taking   OuterA2    weren't
       constraint added
			      constrained, interfering with metaprogramming
