  • Constructor Details

    • RestrictionImpl

      public RestrictionImpl(org.apache.jena.graph.Node n, org.apache.jena.enhanced.EnhGraph m)

  • Method Details

    • findRootStatement

      public Optional<OntStatement> findRootStatement()
      Description copied from class: OntObjectImpl
      Finds the first declaration root statement. The graph may contain several triples with predicate rdf:type and this ontology object as a subject. In this case, the result is unpredictable.
      Overrides:
      findRootStatement in class OntClassImpl
      Returns:
      Optional around OntStatement that supports plain annotation assertions

    • objectType

      public Class<? extends OntClass> objectType()
      Description copied from class: OntObjectImpl
      Gets a public ont-object type identifier.
      Specified by:
      objectType in interface OntObject
      Specified by:
      objectType in class OntClassImpl
      Returns:
      Class, the actual type of this object

    • 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
