```
public class DatasetGraphViewGraphs
extends DatasetGraphWrapper
```
Wrap a DatasetGraph with implementations of DatasetGraph.getDefaultGraph() and DatasetGraph.getGraph(org.apache.jena.graph.Node) that use the view graph mechanism.

public Graph getDefaultGraph()

    Description copied from interface: DatasetGraph
    
    Get the default graph as a Jena Graph
    
    Specified by:
    
    getDefaultGraph in interface DatasetGraph
    
    Overrides:
    
    getDefaultGraph in class DatasetGraphWrapper
  - getGraph
```
public Graph getGraph(Node graphNode)
```
    Description copied from interface: DatasetGraph
    
    Get the graph named by graphNode : returns null when there is no such graph. NB Whether a dataset contains a graph if there are no triples is not defined - see the specific implementation. Some datasets are "open" - they have all graphs even if no triples.
