    • testAnnotationAxiomOverlaps

      public static boolean testAnnotationAxiomOverlaps(org.apache.jena.ontapi.model.OntStatement statement, AxiomsSettings conf, org.semanticweb.owlapi.model.AxiomType<? extends org.semanticweb.owlapi.model.OWLObjectPropertyAxiom> o, org.semanticweb.owlapi.model.AxiomType<? extends org.semanticweb.owlapi.model.OWLDataPropertyAxiom> d)
      Auxiliary method for simplification code. Used in Annotation Translators. If the specified statement also belongs to the another type of axiom and such situation is prohibited in the config then returns false. This is for three kinds of statements:
      • A1 rdfs:subPropertyOf A2
      • A rdfs:domain U
      • A rdfs:range U
      Each of them is wider than the analogous statement for object or data property, e.g. P rdfs:range C could be treated as A rdfs:range U, but not vice versa.
      Parameters:
      statement - OntStatement to test, not null
      conf - AxiomsSettings, not null
      o - AxiomType.SUB_OBJECT_PROPERTY or AxiomType.OBJECT_PROPERTY_DOMAIN or AxiomType.OBJECT_PROPERTY_RANGE
      d - AxiomType.SUB_DATA_PROPERTY or AxiomType.DATA_PROPERTY_DOMAIN or AxiomType.DATA_PROPERTY_RANGE
      Returns:
      true if the statement is good to be represented in the form of annotation axiom
