CODE:

        FilterController filterController = Lookup.getDefault().lookup(FilterController.class);        EdgePartitionFilter EdgePartitionFilter = new EdgePartitionFilter(graphModel.getEdgeTable().getColumn("kind"), appearanceModel);        EdgePartitionFilter.unselectAll();        EdgePartitionFilter.addPart("Function");        Query query = filterController.createQuery(EdgePartitionFilter);        GraphView view = filterController.filter(query);        graphModel.setVisibleView(view);                                  graph = graphModel.getDirectedGraphVisible();        System.out.println("Nodes: " + graph.getNodeCount() + " Edges: " + graph.getEdgeCount());
