[jira] [Commented] (JENA-1786) DatasetGraphMonitor exposes unwrapped graphs

["Pavel Mikhailovskii (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/JENA-1786?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16984277#comment-16984277 ] 

Pavel Mikhailovskii commented on JENA-1786:
-------------------------------------------

It's actually a more generic problem and should probably be fixed in DatasetGraphWrapper.

> Both DatasetGraphMonitor.getDefaultGraph and DatasetGraphMonitor.getGraph  expose unwrapped graphs from the underlying DatasetGraph. Any changes made to those graphs skip DatasetGraphMonitor's change monitoring. 
> To reproduce:
> {code:java}
>    public class TestDatasetMonitor extends BaseTest {
>     ...
>     @Test public void countChanges_05() {
>         DatasetGraph dsgBase = DatasetGraphFactory.create() ;
>         DatasetChangesCounter dsgChanges = new DatasetChangesCounter() ;
>         DatasetGraph dsg = new DatasetGraphMonitor(dsgBase, dsgChanges) ;
>         check(dsgChanges, 0, 0, 0, 0) ;
>         Graph g = dsg.getDefaultGraph();
>         g.add(quad1.asTriple()) ;
>         g.delete(quad1.asTriple()) ;
>         g.add(quad1.asTriple()) ;
>         g.delete(quad1.asTriple()) ;
>         check(dsgChanges, 2, 2, 0, 0) ; 
>     }
> {code}
