  • Constructor Details

    • ObjectHasValueImpl

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

  • Method Details

    • objectType

      public Class<OntClass.ObjectHasValue> objectType()
      Description copied from class: OntObjectImpl
      Gets a public ont-object type identifier.
      Specified by:
      objectType in interface OntObject
      Overrides:
      objectType in class OntClassImpl.OnPropertyRestrictionImpl<OntObjectProperty,OntClassImpl.ObjectHasValueImpl>
      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
      See Also:
      • RDFNode.as(Class)
      • RDFNode.canAs(Class)

    • getProperty

      OntObjectProperty getProperty()
      Gets the property, that this OntClass.UnaryRestriction has inside its RDF structure on predicate owl:onProperty.
      Returns:
      P

    • getValue

      OntIndividual 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
      See Also:
      • SetValue.setValue(RDFNode)

    • setValue

      OntClass.ObjectHasValue setValue(OntIndividual value)
      Sets the specified value (a filler in OWL-API terms) into this class or data range expression.

      A value can be null if this is a Cardinality Restriction (the null-filler is considered as owl:Thing for an object restriction and as RDFS.Literal for a data restriction).

      Parameters:
      value - V, possible null in case of Cardinality Restriction
      Returns:
      this instance to allow cascading calls
      See Also:
      • HasValue.getValue()

    • setProperty

      OntClass.ObjectHasValue setProperty(OntObjectProperty property)
      Sets the given property into this Restriction (as an object with predicate owl:onProperty if it is Unary Restriction).
      Parameters:
      property - P, not null
      Returns:
      this instance to allow cascading calls
