Hi Emanuel,
Not with a direct method. You can obtain those sets with a modified version
of previous solution.
// create the ontology...
OntModel model = ModelFactory.createOntologyModel();
OntClass classA = model.createClass("http://bla.bla/A");
OntClass classB = model.createClass("http://bla.bla/B");
OntClass classC = model.createClass("http://bla.bla/C");
OntClass classD = model.createClass("http://bla.bla/D");
classA.addDisjointWith(classB);
classA.addDisjointWith(classC);
classC.addDisjointWith(classD);
// list disjoint sets...
ResIterator classesHasDisjoint = model
.listResourcesWithProperty(OWL.disjointWith);
while (classesHasDisjoint.hasNext()) {
OntClass cls = classesHasDisjoint.next().as(OntClass.class);
List<OntClass> disjointList = cls.listDisjointWith().toList();
disjointList.add(0, cls);
System.out.println(disjointList);
}
Console output:
[http://bla.bla/A, http://bla.bla/C, http://bla.bla/B]
[http://bla.bla/C, http://bla.bla/D]
Best,
Tayfun
