xtext inject or access RootModel into ScopeProvider

I am using Xtext 2.3.1

Within my ScopeProvider I want to use the currently parsed rootModel. How to do so? Can I inject the RootModel or can I use the context?

public class MyLanguageScopeProvider extends AbstractDeclarativeScopeProvider {

    public IScope scope_MyLangElement_ref(EObject context, EReference reference) {
        HashMap<QualifiedName, EObject> elements = new HashMap<QualifiedName, EObject>();

        // access model here, sth like:
        RootModel rootModel = // ....

        return new MapBasedScope(elements);
    }

}
Solution

  • EcoreUtil.getRootContainer(context) should do the trick.
