I use some java classes that are imported by java-stubs. Is there a way in MPS to generate a list<string> of the classes that inherit from a concrete abstract class that is defined in these java-stubs? This list could be very useful for a custom completion menu in my editor.
For concepts in MPS this would be quite easy but can you do the same for classes in java stubs? (I do not want to transfer the whole Java code to MPS.)
