Method Detail

getRDFService

RDFService getRDFService()

Returns:

RDFService - an RDFService instance

getShortTermRDFService

RDFService getShortTermRDFService()

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().

Returns:

RDFService - an RDFService instance

registerListener

void registerListener(ChangeListener changeListener)
               throws RDFServiceException

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.

Parameters:

changeListener - - the change listener

Throws:

RDFServiceException

unregisterListener

void unregisterListener(ChangeListener changeListener)
                 throws RDFServiceException

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.

Parameters:

changeListener - - the change listener

Throws:

RDFServiceException

registerJenaModelChangedListener

void registerJenaModelChangedListener(com.hp.hpl.jena.rdf.model.ModelChangedListener changeListener)
                               throws RDFServiceException

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

Parameters:

changeListener - - the change listener

Throws:

RDFServiceException

unregisterJenaModelChangedListener

void unregisterJenaModelChangedListener(com.hp.hpl.jena.rdf.model.ModelChangedListener changeListener)
                                 throws RDFServiceException

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

Parameters:

changeListener - - the change listener

Throws:

RDFServiceException
