> (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>}})
