Methods get...Edges return OWLGraphEdges with no ontology attribute set #66

Closed GoogleCodeExporter closed 9 years ago

Hi, 

OWLGraphEdges returned by method such as getIncomingEdges or getOutgoingEdges 
have no ontology set (getOntology() returns null).

This is problematic when trying to remove or add axioms based on such 
OWLGraphEdges. For instance: 

OWLSubClassOfAxiom ax = factory.getOWLSubClassOfAxiom((OWLClassExpression) 
edge.getSource(), (OWLClassExpression) edgeToTargetExpression(edge));
RemoveAxiom remove = new RemoveAxiom(edge.getOntology(), ax);
manager.applyChange(remove);
//fail with exception: 
//org.semanticweb.owlapi.model.ImmutableOWLOntologyChangeException: Cannot 
apply changes to immutable ontology: null

It would be great if the returned OWLGraphEdges had their ontology attribute 
set.
