Class ConfiguredReasonerListener

java.lang.Object

edu.cornell.mannlib.vitro.webapp.tboxreasoner.ConfiguredReasonerListener

All Implemented Interfaces:

org.apache.jena.rdf.model.ModelChangedListener

public class ConfiguredReasonerListener
extends Object
implements org.apache.jena.rdf.model.ModelChangedListener

Listens for changes on a model. When a change is announced, it is checked for worthiness. If worthy, it is added to a change set. When an ending EditEvent is received, the current change set is passed along to the reasoner driver, and a new change set is begun. Among the criteria for deciding on worthiness is the driving pattern set. In the constructor, a map is made from this set, to reduce the number of tests made against each statement. I don't know whether this optimization is justified. It is possible to "suspend" the listener, so it will ignore any changes. This is useful when the reasoner itself makes changes to the models, so those changes do not trigger additional reasoning.
