Method Details

getLinkSource

public RDFLinkSource getLinkSource()

Specified by:

getLinkSource in interface HasRDFLinkSource

getServiceControl

public Optional<ServiceControl> getServiceControl()

Description copied from interface: RDFEngine

An engine may optionally expose a way to start and stop the underlying service. Note that only a call to AutoCloseable.close() must guarantee to stop the service and free any resources. Only calling ServiceControl.stop() is generally NOT sufficient.

Specified by:

getServiceControl in interface HasServiceControl

Specified by:

getServiceControl in interface RDFEngine

close

public void close()
           throws Exception

Specified by:

close in interface AutoCloseable

Throws:

Exception
