ontClass - Denotes a class to which this value may belong
Returns:
True if this resource has the given class as one of its rdf:type's.
See Also:
Individual.hasOntClass(Resource)

removeRDFType

void removeRDFType(Resource cls)

Remove the statement that this resource is of the given RDF type. If this statement is not true of the current model, nothing happens.

Parameters:
cls - A resource denoting a class that that is to be removed from the classes of this resource
See Also:
Individual.removeOntClass(Resource)

hasRDFType

boolean hasRDFType(String uri)

Answer true if this resource is a member of the class denoted by the given URI.

Parameters:
uri - Denotes the URI of a class to which this value may belong
Returns:
True if this resource has the given class as one of its rdf:type's.
See Also:
Individual.hasOntClass(String)

getCardinality

int getCardinality(Property p)

Answer the cardinality of the given property on this resource. The cardinality is the number of distinct values there are for the property.

Parameters:
p - A property
Returns:
The cardinality for the property p on this resource, as an integer greater than or equal to zero.

setPropertyValue

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.

Parameters:
property - The property to update
value - The new value of the property as an RDFNode, or null to effectively remove this property.

getPropertyValue

RDFNode getPropertyValue(Property property)

Answer the value of a given RDF property for this 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.

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

NodeIterator listPropertyValues(Property property)

Answer an iterator over the values for a given RDF property. Each value in the iterator will be an RDFNode.

Parameters:
property - The property whose values are sought
Returns:
An Iterator over the values of the property

removeProperty

void removeProperty(Property property,
                    RDFNode value)

Remove the specific property-value pair from this resource.

Parameters:
property - The property to be removed
value - The specific value of the property to be removed

remove

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.
