Andy Seaborne commented on JENA-553:
------------------------------------
Here is an alternative implementation of {{DatasetGraphAltDefaultGraph}} that
copies and changes the structure of the dataset, hence avoiding all the
problems of consistently intercepting methods.
However, it requires {{listGraphNodes}} which is potentially expensive. As a
common case will be to access and change just one of the named graph, finding
all graphs is potentially expensive for no real value. Better would be a
{{DatasetGraph}} that derives from {{DatasetGraphCollection}} (as does
{{DatasetGraphMap}}).
{noformat}
static class DatasetGraphAltDefaultGraph extends DatasetGraphMap
{
public DatasetGraphAltDefaultGraph(DatasetGraph dsg, Graph dftGraph) {
super(dftGraph) ;
Iterator<Node> gNames = dsg.listGraphNodes() ;
while(gNames.hasNext()) {
Node gn = gNames.next() ;
addGraph(gn, dsg.getGraph(gn)) ;
}
}
}

> Key: JENA-553
> URL: https://issues.apache.org/jira/browse/JENA-553
> Project: Apache Jena
> Issue Type: Bug
> Components: ARQ
> Affects Versions: Jena 2.11.0, Fuseki 1.0.0
> Reporter: Michael Brunnbauer
>
> This does not generate the triple with "test1" as object:
> {noformat}
> drop graph <http://mytest>;
> insert data { graph <http://mytest> { _:b0 <http://test> "test" }};
> WITH <http://mytest>
> DELETE { ?s ?p "test" }
> INSERT { ?s ?p "test1" }
> WHERE { ?s ?p "test" }
> {noformat}
> But this does (without WITH on default graph):
> {noformat}
> drop DEFAULT;
> insert data { _:b0 <http://test> "test" };
> DELETE { ?s ?p "test" }
> INSERT { ?s ?p "test1" }
> WHERE { ?s ?p "test" }
> {noformat}
