      • 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.

        Answer the rdf:type (ie the class) of this resource. If there is more than one type for this resource, the return value will be one of the values, but it is not specified which one (nor that it will consistently be the same one each time).

        Specified by:
        getRDFType in interface OntResource
        Parameters:
        direct - If true, only consider the direct types of this resource, and not the super-classes of the type(s).
        Returns:
        A resource that is the rdf:type for this resource, or one of them if more than one is defined.

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

        Parameters:
        p - A property

      • 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.
