Hi Dana,
You can do it just like this,
EList<EObject> contents = new ResourceSetImpl().getResource(uri,
true).getContents();
OperationalTransformation transf =
(OperationalTransformation)contents.get(0);
ModelType modelType =
(ModelType)transf.getModelParameter().get(0).getType();
EPackage usedMetamodel = modelType.getMetamodel().get(0);
Well, code a little bit more defensive then me ;).
Note, the AST classes are still from internal packages, though the AST
metamodel structure is pretty stable. It will be open, but can't say when
we have higher prio tasks at the moment.
Regards,
/Radek
