Method Detail

getDatasetWrapper

protected DatasetWrapper getDatasetWrapper()

Specified by:

getDatasetWrapper in class RDFServiceJena

changeSetUpdate

public boolean changeSetUpdate(ChangeSet changeSet)
                        throws RDFServiceException

Description copied from interface: RDFService

Performs a series of additions to and or removals from specified graphs in the RDF store. preConditionSparql is executed against the union of all the graphs in the knowledge base before any updates are made. If the precondition query returns a non-empty result, no updates are made made.

Specified by:

changeSetUpdate in interface RDFService

Specified by:

changeSetUpdate in class RDFServiceJena

Parameters:

changeSet - - a set of changes to be performed on the RDF store.

Returns:

boolean - indicates whether the precondition was satisfied

Throws:

RDFServiceException

createQueryExecution

protected com.hp.hpl.jena.query.QueryExecution createQueryExecution(String queryString,
                                                                    com.hp.hpl.jena.query.Query q,
                                                                    com.hp.hpl.jena.query.Dataset d)

Overrides:

createQueryExecution in class RDFServiceJena

close

public void close()

Description copied from interface: RDFService

Frees any resources held by this RDFService object The implementation of this method should be idempotent so that multiple invocations do not cause an error.

Specified by:

close in interface RDFService

Overrides:

close in class RDFServiceJena
