Find ItemPropertyDescriptors by EClass instead of concrete instance [message #899807]

Is there a way to get an all IItemPropertyDescriptors by its EClass instead of providing a concrete instance of that type?

E.g.

I have the type MyType for which the gen model will generate a MyTypeItemProvider.
If I want to get all IItemPropertyDescriptors, I have to do it this way:

AdapterFactoryItemDelegator afid = new AdapterFactoryItemDelegator(new ComposedAdapterFactory(ComposedAdapterFactory.Descriptor.Registry.INSTANCE));

MyType obj = MyModelFactory.eInstance.createMyType();
List<IItemPropertyDescriptor> desc = afid.getPropertyDescriptors(obj);

If I just provide the EClass to the getPropertyDescriptors(), then I will get the EClassItemProvider of ecore's edit model...

Any hints?

That's all there is available.
