java.lang.Object

edu.cornell.mannlib.vitro.webapp.tboxreasoner.impl.jfact.JFactTBoxReasoner

All Implemented Interfaces:

TBoxReasoner

public class JFactTBoxReasoner
extends Object
implements TBoxReasoner

An implementation of the JFact reasoner for the TBox. It maintains a model of all the assertions it has been given, adding or removing statements as change sets are received. Each time a change is received, it will create a fresh ontology from the assertions model, and apply a reasoner to that ontology. A model of inferences is built by querying the reasoner. The assertions and inferences are combined into an OntModel, which is kept to answer queries. ----------------- This class it not thread-safe.
