public RDFServiceModel(com.hp.hpl.jena.query.Dataset dataset)

Create an RDFService to access a Jena Dataset

Parameters:

dataset - Jena Dataset

Method Detail

getDatasetWrapper

protected DatasetWrapper getDatasetWrapper()

Specified by:

getDatasetWrapper in class RDFServiceJena

changeSetUpdate

public boolean changeSetUpdate(ChangeSet changeSet)

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
