public class OntResourceImpl extends ResourceImpl implements OntResource

Abstract base class to provide shared implementation for implementations of ontology resources.

  • Field Details

      public static final String[] KNOWN_LANGUAGES
      List of namespaces that are reserved for known ontology languages

    • factory

      public static Implementation factory
      A factory for generating OntResource facets from nodes in enhanced graphs. Note: should not be invoked directly by user code: use as() instead.

  • Constructor Details

    • OntResourceImpl

      public OntResourceImpl(Node n, EnhGraph g)

      Construct an ontology resource represented by the given node in the given graph.

  • Method Details

    • getOntModel

      public OntModel getOntModel()

      Answer the model that this resource is attached to, assuming that it is an OntModel. If this resource is not attached to any model, or is (unusually) attached to a model that is not an OntModel, answer null.

      Specified by:
      getOntModel in interface OntResource
      Returns:
      The ont model that this resource is attached to, or null.

    • removeRDFType

      cls - A resource denoting a class that that is to be removed from the classes of this resource
      See Also:

    • getCardinality

      Specified by:
      getCardinality in interface OntResource
      Parameters:

    • setPropertyValue

      public void setPropertyValue(Property property, RDFNode value)

      Set the value of the given property of this ontology resource to the given value, encoded as an RDFNode. Maintains the invariant that there is at most one value of the property for a given resource, so existing property values are first removed. To add multiple properties, use addProperty.

      Specified by:
      setPropertyValue in interface OntResource
      Parameters:
      property - The property to update
      value - The new value of the property as an RDFNode, or null to effectively remove this property.

    • getPropertyValue

      public RDFNode getPropertyValue(Property property)

      Answer the value of a given RDF property for this ontology resource, or null if it doesn't have one. The value is returned as an RDFNode, from which the concrete data value can be extracted for literals. If the value is a resource, it will present the OntResource facet. If there is more than one RDF statement with the given property for the current value, it is not defined which of the values will be returned.

      Specified by:
      getPropertyValue in interface OntResource
      Parameters:
      property - An RDF property
      Returns:
      An RDFNode whose value is the value, or one of the values, of the given property. If the property is not defined the method returns null.

    • listPropertyValues

      public NodeIterator listPropertyValues(Property property)

      Answer an iterator over the set of all values for a given RDF property. Each value in the iterator will be an RDFNode, representing the value (object) of each statement in the underlying model.

      Specified by:
      listPropertyValues in interface OntResource
      Parameters:
      property - The property whose values are sought
      Returns:
      An Iterator over the values of the property

    • remove

      public void remove()

      Removes this resource from the ontology by deleting any statements that refer to it, as either statement-subject or statement-object. If this resource is a property, this method will not remove statements whose predicate is this property.

      Caveat: Jena RDF models contain statements, not resources per se, so this method simulates removal of an object by removing all of the statements that have this resource as subject or object, with one exception. If the resource is referenced in an RDF List, i.e. as the object of an rdf:first statement in a list cell, this reference is not removed. Removing an arbitrary rdf:first statement from the midst of a list, without doing other work to repair the list, would leave an ill-formed list in the model. Therefore, if this resource is known to appear in a list somewhere in the model, it should be separately deleted from that list before calling this remove method.

      remove in interface OntResource
