Hi Ed
Yes, but all auto-generated EObjects have a no argument constructor, so
he can just create an instance from the class.

Ed

It sounded more like he had the interface for it and the constructor for
the generated class is protected by default...

Hi Ed(s) :)
yes, I only have the java.lang.Class, and I'd need a solution who would
work also in 'standalone' mode... for the moment, I'll do without
thanks

Exactly as you said.
You can imagine that the underlying context is Xtext :)

Lorenzo,
With the Xcore work, we have indexing support for *.genmodel/*.ecore as
well as for *.xcore so I imagine you'll be able to reuse that at some
point soon: https://github.com/merks/Xcore
