Method Detail

getRDFService

public RDFService getRDFService()

Specified by:

getRDFService in interface RDFServiceFactory

Returns:

RDFService - an RDFService instance

getShortTermRDFService

public RDFService getShortTermRDFService()

Description copied from interface: RDFServiceFactory

Returns an instance of RDFService that may not support being left idle for long periods of time. RDFService instances returned by this method should be immediately used and closed, not stored in (for example) session or context attributes. This method exists to enable performance improvements resulting from a lack of need to handle database connection or other service timeouts and reconnects. The results provided by RDFService instances returned by this method must be identical to those provided by instances returned by getRDFService().

Specified by:

getShortTermRDFService in interface RDFServiceFactory

Returns:

RDFService - an RDFService instance

registerListener

public void registerListener(ChangeListener changeListener)
                      throws RDFServiceException

Description copied from interface: RDFServiceFactory

Registers a listener to listen to changes in any graph in the RDF store. Any RDFService objects returned by this factory should notify this listener of changes.

Specified by:

registerListener in interface RDFServiceFactory

Parameters:

changeListener - - the change listener

Throws:

RDFServiceException

unregisterListener

public void unregisterListener(ChangeListener changeListener)
                        throws RDFServiceException

Description copied from interface: RDFServiceFactory

Unregisters a listener from listening to changes in the RDF store. Any RDFService objects returned by this factory should no longer notify this listener of changes.

Specified by:

unregisterListener in interface RDFServiceFactory

Parameters:

changeListener - - the change listener

Throws:

RDFServiceException

registerJenaModelChangedListener

public void registerJenaModelChangedListener(org.apache.jena.rdf.model.ModelChangedListener changeListener)
