-----------------------------------
Summary: Add find operations for {{DatasetGraph}} for the union
graph.
Key: JENA-1074
URL: https://issues.apache.org/jira/browse/JENA-1074
Project: Apache Jena
Issue Type: Brainstorming
Components: ARQ
Affects Versions: Jena 3.0.0
Reporter: Andy Seaborne
Priority: Minor
(This follows on from JENA-1064)
{{DatasetGraphBaseFind}} now has a {{find}} operations for the union graph
added to make implementation easier.
Should operation(s) be exposed in the core interface {{DatasetGraph}} (the
application contract)? If so, how?
The operations to consider include:
* {{findInUnionGraph}} ({{Iterator<Triple>}})
* {{findQuadsInUnionGraph}} ({{Iterator<Quad>}})
* {{findInDftGraph}} ({{Iterator<Quad>}} - inconsistent naming with above)
At the moment {{findInDftGraph}} returns quads and documents
{{DatasetGraph.getDefaultGraph().find()}} as being the way to get triples. This
suggests a different style where {{DatasetGraph}} has:
* {{DatasetGraph.getUnionGraph()}}
* {{DatasetGraphFind.findInUnionGraph}} ({{Iterator<Quad>}})
