[cellml-dev] RDF Representation

Hi,

When I generate stub classes from the IDL file, I get Stubs with the
queryInterface and addRef and releaseRef methods. However, as they only
implement the RDFRepresentation interface and multiple inheritance is not
possible in Java, I can't see a way that I can use the methods generated by
that in order to access queryInterface.

If you have any ideas how to work around this, I would be very grateful.
Annotating CellML models will be much more difficult if I can't use the
CellML DOM API to access the RDF.

Thank you,
Morgan

You will need to query_interface the model (casting is not
sufficient)... this may be an oversight in the Java bindings, because
I'm not sure we provided a way to do that, as add_ref and release_ref
are handled automatically, and in hiding them from manual use by Java
programs, I think we have also hidden query_interface.

This is something I will need to look into next week.

Best wishes,
Andrew
