public interface Dataset

Query is over a Dataset, a collection of named graphs and a background graph (also called the default graph or unnamed graph).

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() Get the default graph as a Jena 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) Get a graph by name as a Jena Model
java.util.Iterator<java.lang.String>	listNames() List the names

Method Detail

getNamedModel

com.hp.hpl.jena.rdf.model.Model getNamedModel(java.lang.String uri)

Get a graph by name as a Jena Model

containsNamedModel

boolean containsNamedModel(java.lang.String uri)

Does the dataset contain a model with the name supplied?

listNames

java.util.Iterator<java.lang.String> listNames()

List the names

getLock

com.hp.hpl.jena.shared.Lock getLock()

Get the lock for this dataset

asDatasetGraph
