如何获取OWLClassExpression中的元素

Question

请问是否要在OWLClass element之类的ObjectUnionOf OWLClassExpression中提取ObjectUnionOf(<OWLClass> <OWLClass>)， owl-api 中应使用哪种方法我用来获取这两个 OWLClasses ？

Answer 1

方法是OWLObjectVisitor：

OWLObjectVisitorAdapter visitorAdapter = new OWLObjectVisitorAdapter() {
 @Override
 public void visit(OWLObjectUnionOf ce) {
  for (OWLClassExpression e : ce.getOperands()) {
      if (!e.isAnonymous()) {
     System.out.println("VisitorAdaptor OWLClass:"+e);
         }
     }
    }
  };
classExpression.accept(visitorAdapter);
