> Key: JENA-222
> URL: https://issues.apache.org/jira/browse/JENA-222
> Project: Apache Jena
> Issue Type: Bug
> Components: TDB

> Reporter: Rupert Westenthaler
> Assignee: Andy Seaborne
> Priority: Minor

> using
> Dataset dataset = TDBFactory.createDataset(dir);
> Model model dataset.getNamedModel("urn:x-arq:UnionGraph");
> Graph graph = model.getGraph();
> int size = graph.size();
> size will always report zero regardless of the amount of triples stored in
> the different named models of the dataset.
> I think this is because com.hp.hpl.jena.tdb.store.GraphNamedTDB#countThis()
> would need special treatment in case of "isQuadUnionGraph(graphNode) == true"
