  • Method Details

    • getArg

      A getArg()
    • arguments

      default Stream<A> arguments()
      Description copied from interface: OntSWRL.Atom
      Lists all arguments from this Atom.
      Specified by:
      arguments in interface OntSWRL.Atom<P extends OntObject>
      Returns:
      Stream of OntSWRL.Args
    • getModel

      OntModel getModel()
      Returns the ontology model associated with this resource. If the Resource was not created by a Model, the result may be null.
      Specified by:
      getModel in interface org.apache.jena.rdf.model.RDFNode
      Returns:
      OntModel
    • isLocal

      boolean isLocal()
      Determines if this Ontology Resource is locally defined. This means that the resource definition (i.e., a the root statement) belongs to the base ontology graph. If the ontology contains subgraphs (which should match owl:imports in OWL) and the resource is defined in one of them, than this method called from top-level interface will return false.
      Returns:
      true if this resource is local to the base model graph.
    • getAs

      default <X extends org.apache.jena.rdf.model.RDFNode> X getAs(Class<X> type)
      Safely converts this RDF resource to the given type interface, if it is possible. Otherwise, returns null. A calling of this method is effectively equivalent to the expression this.canAs(type) ? this.as(type) : null.
      Type Parameters:
      X - any subtype of RDFNode
      Parameters:
      type - a Class-type of the desired RDF view (interface)
      Returns:
      an instance of the type X or null
