Class ConfigurationTripleSourceTDB

java.lang.Object

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

edu.cornell.mannlib.vitro.webapp.triplesource.impl.tdb.ConfigurationTripleSourceTDB

All Implemented Interfaces:

Application.Component, Application.Module, TripleSource

public class ConfigurationTripleSourceTDB
extends ConfigurationTripleSource

A TDB triple-store has no concept of connections, so we need not manage them 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. We keep a copy of the RDFService wrapped in an Unclosable shell, and hand that out when requested. The inner RDFService is only closed on shutdown(). Memory-map all of the configuration models, and add the standard decorators.
