Method Detail

ontologyUpdated

void ontologyUpdated(Ontology changedOntology,
                     Ontology sourceOntology,
                     java.util.List<OntologyChangeEvent> changes,
                     java.util.Set<Entity> addedEntities,
                     java.util.Set<Entity> removedEntities)

Called when an ontology has changed.

Parameters:

changedOntology - the ontology whose axioms have changed

sourceOntology - the ontology at which the axioms have changed

changes - the list of changes

addedEntities - the set of entities that were added to the model

removedEntities - the set of entities that were removed from the model

ontologyPropertyUpdated

void ontologyPropertyUpdated(Ontology changedOntology,
                             Ontology sourceOntology,
                             OntologyChangeEvent.ChangeType changeType,
                             java.lang.String ontologyPropertyURI,
                             java.lang.String value)

Called when an ontology property has been added or removed.

Parameters:

changedOntology - the ontology whose properties have changed

sourceOntology - the ontology at which the axioms have changed

changeType - the type of the changed

ontologyPropertyURI - the URI of the ontology property

value - the value of the ontology property

ontologyChangedDrastically

void ontologyChangedDrastically(Ontology changedOntology)

Called when the ontology has been changed in a drastic way. In this case the delta about the ontology changes is unavailable, and the client should process entire ontology from scratch.

Parameters:

changedOntology - the ontology

ontologyClosed

void ontologyClosed(Ontology closedOntology)

Called when the ontology has been closed.

Parameters:

closedOntology - the ontology
