All Implemented Interfaces:

public class DatasetGraphOneNgImpl extends org.apache.jena.sparql.core.DatasetGraphBaseFind implements DatasetGraphOneNg
Adapted from DatasetGraphOne ~ Claus Stadler DatasetGraph of a single named graph graph.

Fixed as one graph (the default) - named graphs can not be added nor the default graph changed, only the contents modified.

This dataset passes transactions down to a nominated backing DatasetGraph.

It is particular suitable for use in streams where each element is a single named graph.
