Class DatasetImpl

java.lang.Object
  com.hp.hpl.jena.sparql.core.DatasetImpl

All Implemented Interfaces:

Dataset

public class DatasetImpl
extends java.lang.Object
implements Dataset

Wrapper around a DatasetGraph. See also DataSourceImpl.

Constructor Summary

DatasetImpl(DatasetGraph dsg)

DatasetImpl(com.hp.hpl.jena.rdf.model.Model model)

Method Summary

DatasetGraph	asDatasetGraph() Get the dataset in graph form
void	close() Close the dataset, potentially releasing any associated resources.
boolean	containsNamedModel(java.lang.String uri) Does the dataset contain a model with the name supplied?
com.hp.hpl.jena.rdf.model.Model	getDefaultModel() Return the default model
com.hp.hpl.jena.shared.Lock	getLock() Get the lock for this dataset
com.hp.hpl.jena.rdf.model.Model	getNamedModel(java.lang.String uri) Return a model for the named graph - repeated calls so not guarantee to return the same Java object
java.util.Iterator<java.lang.String>	listNames() List the names
