public static class OntObjectPropertyImpl.NamedImpl extends OntObjectPropertyImpl implements OntObjectProperty.Named
  • Constructor Details

    • NamedImpl

      public NamedImpl(org.apache.jena.graph.Node n, org.apache.jena.enhanced.EnhGraph g)
  • Method Details

    • createInverse

      public OntObjectProperty.Inverse createInverse()
      Description copied from interface: OntObjectProperty.Named
      Creates or finds an inverse of this property. The searching is performed only in the base graph, so it is possible to have more than one anonymous object property expressions in case the named companion belongs to some subgraph. For a single-graph model a named object property can be answered by one and only one Inverse object property expression.
      Specified by:
      createInverse in interface OntObjectProperty.Named
      Returns:
      OntObjectProperty.Inverse - an anonymous OntObjectProperty resource (fresh or existing)
    • isBuiltIn

      public boolean isBuiltIn()
      Description copied from interface: OntEntity
      Determines if this is a builtin entity. In a standard (default) OWL2 vocabulary an entity is builtin if it is:
      • a class and its IRI is either owl:Thing or owl:Nothing
      • an object property and its IRI is either owl:topObjectProperty or owl:bottomObjectProperty
      • a data property and its IRI is either owl:topDataProperty or owl:bottomDataProperty
      • a datatype and its IRI is either rdfs:Literal, or rdf:PlainLiteral, or it is from the OWL 2 datatype map
      • an annotation property and its IRI is one of the following:
        • rdfs:label
        • rdfs:comment
        • rdfs:seeAlso
        • rdfs:isDefinedBy
        • owl:deprecated
        • owl:versionInfo
        • owl:priorVersion
        • owl:backwardCompatibleWith
        • owl:incompatibleWith
      Note: all the listed above IRIs refer to the default Builtins Vocabulary. A model with different Builtins vocabulary will naturally have a different Set of builtin IRIs, and this method will return a different result.
      Specified by:
      isBuiltIn in interface OntEntity
      Returns:
      true if it is a built-in entity

    • objectType

      public Class<OntObjectProperty.Named> objectType()
      Description copied from class: OntObjectImpl
      Gets a public ont-object type identifier.
      Specified by:
      objectType in interface OntObject
      Overrides:
      objectType in class OntObjectImpl
      Returns:
      Class, the actual type of this object
    • inModel

      public org.apache.jena.rdf.model.Property inModel(org.apache.jena.rdf.model.Model m)
      Specified by:
      inModel in interface org.apache.jena.rdf.model.Property
      Specified by:
      inModel in interface org.apache.jena.rdf.model.RDFNode
      Specified by:
      inModel in interface org.apache.jena.rdf.model.Resource
      Overrides:
      inModel in class org.apache.jena.rdf.model.impl.ResourceImpl
    • 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 OntObjectImpl
      Returns:
      Optional around OntStatement that supports plain annotation assertions
    • getOrdinal

      public int getOrdinal()
      Specified by:
      getOrdinal in interface org.apache.jena.rdf.model.Property
    • 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
