Class DatasetOne

java.lang.Object

org.apache.jena.sparql.core.DatasetImpl

org.apache.jena.sparql.core.DatasetOne

All Implemented Interfaces:

Dataset, Transactional

public class DatasetOne
extends DatasetImpl

A dataset that just hold a single model as the default graph. It is particularly appropriate for use with inference models.

API Note:

This class makes the use of DatasetImpl with one fixed model clearer. It may become useful to have a separate implementation altogether at some time.
