[Bearbeiten] Notes

Diese Art Merkmal wird durch std::scoped_allocator_adaptor eingesetzt und kann durch individuelle Zuordnern verwendet werden, um zu bestimmen, ob das Objekt aufgebaut sich geeignet ist, unter Verwendung einer Zuweisungseinrichtung (zB ist ein Container), in welchem ​​Fall eine Zuweisungseinrichtung an den Konstruktor übergeben werden müssen .
Original:
This type trait is used by std::scoped_allocator_adaptor and may be used by custom allocators to determine whether the object being constructed is itself capable of using an allocator (e.g. is a container), in which case an allocator should be passed to its constructor.
