std::scoped_allocator_adaptor<OuterAlloc,InnerAlloc...>::inner_allocator
// 1)
inner_allocator_type& inner_allocator() noexcept;
// 2)
const inner_allocator_type& inner_allocator() const noexcept;
Obtains a reference to the inner allocator used to declare this scoped_allocator_adaptor.
If sizeof...(InnerAllocs) == 0
, that is, no inner allocators were declared, returns *this
.
Otherwise returns a reference to std::scoped_allocator_adaptor<InnerAllocs...>
, that is,
a scoped allocator composed of all inner allocators of *this
, with the first inner allocator becoming the outer allocator.
Parameters
(none)
Return value
A reference to the inner allocator, which is itself a std::scoped_allocator_adaptor.
