[GitHub] jena issue #260: JENA-1074: Provide a union graph for DatasetGraph

Github user afs commented on the issue:

    https://github.com/apache/jena/pull/260
  
    The PR keeps "find" operations on `DatasetGraph` returning `Iterator<Quad>`. A graph is used for`Iterator<Triple>`.
    
    The PR adds one new operation: `DatasetGraph.getUnionGraph()`.
    
    The implementation in `DatasetGraphBase` uses `GraphUnionRead` which uses `DatasetGraph.findNG(Quad.unionGraph, ?, ?, ?)`.
    
    `Graph.find()` (no arguments) is added for convenience and to match `DatasetGraph.find()`.
