Method Detail

startup

public void startup(Application application,
                    ComponentStartupStatus ss)

Description copied from interface: Application.Component

This should be called only once, and should be the first call on this Component.

getRDFServiceFactory

public RDFServiceFactory getRDFServiceFactory()

getRDFService

public RDFService getRDFService()

getDataset

public com.hp.hpl.jena.query.Dataset getDataset()

getModelMaker

public com.hp.hpl.jena.rdf.model.ModelMaker getModelMaker()

getShortTermOntModels

public OntModelCache getShortTermOntModels(RDFService shortTermRdfService,
                                           OntModelCache longTermOntModelCache)

Use models from the short-term RDFService, since there is less contention for the database connections that way. The exceptions are the memory-mapped models. By keeping them, we also keep their sub-models. Set up the Union models again also, so they will reference the short-term models.

toString

public String toString()

Overrides:

toString in class Object

shutdown

public void shutdown(Application application)

Description copied from interface: Application.Component

This should be called only once, and should be the last call on this Component.
