Package edu.cornell.mannlib.vitro.webapp.triplesource.impl.sparql

Class ContentTripleSourceSPARQL

java.lang.Object

edu.cornell.mannlib.vitro.webapp.modules.tripleSource.ContentTripleSource

edu.cornell.mannlib.vitro.webapp.triplesource.impl.sparql.ContentTripleSourceSPARQL

All Implemented Interfaces:

Application.Component, Application.Module, TripleSource

Direct Known Subclasses:

ContentTripleSourceVirtuoso

public class ContentTripleSourceSPARQL
extends ContentTripleSource

For a SPARQL endpoint, each connection is created as needed by the RDFService, so there is no need to manage connections here. As a result, we have a single RDFService, a RDFServiceFactory that always returns that single RDFService, a single instance of the Dataset and the ModelMaker. Memory-map the small content models, and add the standard decorators.
