public static interface OntClass.NaryRestriction<O extends OntObject,P extends OntRelationalProperty> extends OntClass.Restriction
An abstraction that unites all Restrictions with the predicate owl:onProperties.
  • Method Details

    • 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
      See Also:
      • RDFNode.as(Class)
      • RDFNode.canAs(Class)
    • getProperty

      default P getProperty()
      Gets the first property from owl:onProperties []-list. Currently, in OWL2, a []-list from n-ary Restrictions may contain one and only one (data) property.
      Returns:
      P
      See Also:
    • getList

      RDFNodeList<P> getList()
      Gets an unmodifiable []-list with items of the type E
      Returns:
      RDFNodeList
    • getValue

      O getValue()
      Gets an RDF-value (a filler in OWL-API terms) encapsulated by this expression (that can be either class or data range expression).

      The result is not null even if it is an Unqualified Cardinality Restriction, that has no explicit filler in RDF (the filler is expected to be either owl:Thing for object restriction or RDFS.Literal for data restriction).

      Returns:
      V, not null
