In Spring4D how to register multiple auto factories for same interface

Question

I want to provide the constructor arguments to the following class via the container but am unable to find a way of registering the multiple auto factories.

TItemFactory = class(TInterfacedObject, IItemFactory)
private
  fFactories: TArray<Func<IHost,IItem>>;
protected
  function CreateInstance(Host: IHost): TArray<IItem>;
public
  constructor Create(Factories: TArray<Func<IHost,IItem>>);
end;

If I wanted to have multiple types of items I could register them as

GlobalContainer.RegisterType<IItem,TItem1>('Item1');
GlobalContainer.RegisterType<IItem,TItem2>('Item2');

If I only had one type of item I could easily

GlobalContainer.RegisterType<IItem,TItem1>;
GlobalContainer.RegisterFactory<Func<IHost,IItem>>;

But I can see there is no point in naming multiple auto factories as they only reference IItem and not TItem1 or TItem2.

Simple, look at the parameters of RegisterFactory, there are two overloads where you can specify the resolvedServiceName.

GlobalContainer.RegisterFactory<Func<IHost, IItem>>('ItemFactory1', 'Item1');
GlobalContainer.RegisterFactory<Func<IHost, IItem>>('ItemFactory2', 'Item2');
