Method Detail

containsUnreferencedEntity

public static boolean containsUnreferencedEntity(OWLOntology ontology,
                                                 OWLDescription desc)

Determines if a class description contains any unreferenced entities with respect to the ontology that contains the entailments which are being explained.

Parameters:

desc - The description to be searched

Returns:

true if the description references entities that the ontology that contains entailments which are being explained, otherwise false

removeAxiom

public static java.util.Set<OWLOntology> removeAxiom(OWLAxiom axiom,
                                                     java.util.Set<OWLOntology> ontologies,
                                                     OWLOntologyManager manager)
                                              throws OWLOntologyChangeException

Removes an axiom from all the given ontologies that contains the axiom and returns those ontologies.

Parameters:

axiom - axiom being removed

ontologies - ontologies from which axiom is being removed

manager - manager to apply the actual change

Returns:

set of ontologies that have been affected

Throws:

OWLOntologyChangeException
