[jira] [Created] (JENA-1478) DifferenceDatasetGraph.contains

Andy Seaborne created JENA-1478:
-----------------------------------

             Summary: DifferenceDatasetGraph.contains
                 Key: JENA-1478
                 URL: https://issues.apache.org/jira/browse/JENA-1478
             Project: Apache Jena
          Issue Type: Bug
    Affects Versions: Jena 3.6.0
            Reporter: Andy Seaborne
             Fix For: Jena 3.7.0


(Assuming "difference is set-difference" not symmetric difference")

defined "contains" as 

{noformat}
public boolean contains(Node g, Node s, Node p, Node o) {
    return both(dsg -> dsg.contains(g, s, p, o));
}
{noformat}

This should be:

{noformat}
public boolean contains(Node g, Node s, Node p, Node o) {
    return getLeft().contains(g, s, p, o) && ! getRight().contains(g, s, p, o);
}
{noformat}
