[xtext] abstract types [message #46560]

Hi,

Would it make sense to mark some types in the generated Ecore model as
abstract? As for instance the type 'Type' generated from the example
grammar:

Model :
(imports+=Import)*
(elements+=Type)*;

Import :
'import' importURI=STRING;

Type:
DataType | Class;

...

As I remember it this wasn't possible in oAW Xtext, but I think this
should be possible in TMF Xtext.

Regards,

--knut

Hi Knut,

I like your suggestion although I don't think it will make it into Xtext
0.7.0. Please file a bug (an provide a patch ;-).
It is currently possible to use the IXtext2EcorePostProcessor to mark
"Type" as abstract.

Regards,
Sebastian
