How do Xtext dev manage to have custom impl for emf classes? [message #1015833]

Hi,

I noticed some of the implementation for the JavaVMTypes emf classes are custom ones.

What's the trick for having such a custom impl that is used everywhere (in particular if I have generated classes by another grammar extending some fo the JavaVMTypes emf classes)?

Thanks for any tips :)

Hi Xtext comes with a workflow component called ecoregenerator that
enables the generation gap pattern for ecore.

Hi, ok but I coudln't see it used for commons.types!

I saw that xbase was using it while refering to commons.types src folder, but that's all.

It works, and if I want my language, which relies on the EMF meta-model previously generated using this component, to also exploits the custom implementation (in a case of a grammar rule that returns a class with a custom impl), can I do it without having to manage the ecore model by hand instead of generating it with xtext?

Because with the default EcoreGeneratorFragment, the custom impl are not taken into account...

So, do you think I should report this as a bug maybe?
