public interface OntProperty extends OntResource, Property
Interface encapsulating a property in an ontology. This is an extension to the standard
Property
interface, adding a collection of convenience methods for accessing the additional semantic features of properties in OWL and RDFS such as domain, range, inverse, etc. Not all such capabilities exist in all supported ontology languages.

getInverse
OntProperty getInverse()
Answer the property that has declared itself to be the inverse of this property, if any such property is defined. If no such property is defined, return null. If more than one inverse is defined, return an arbitrary selection.
Note that this method is slightly different from
getInverseOf()
. Suppose that we have::p an owl:ObjectProperty. :q an owl:ObjectProperty. :p owl:inverseOf :q.
Then,
getInverse()
called on theOntProperty
corresponding toq
will returnp
, sinceq
declares itself to bep
's inverse. However, unless an OWL reasoner is used, callinggetInverse()
onp
will returnnull
. Conversely, absent a reasoner,
ongetInverseOf()
p
will returnq
, but will return null when called onq
. In the presence of an OWL reasoner,getInverse()
andgetInverseOf()
are equivalent, sinceowl:inverseOf
is a symmetric property.- Returns:
- The property that is the inverse of this property, or null.

ExtendedIterator<? extends OntClass> listDeclaringClasses()
Answer an iterator of all of the classes in this ontology, such that each returned class has this property as one of its properties in
OntClass.listDeclaredProperties()
. This simulates a frame-like view of properties and classes; for more details see the RDF frames how-to.- Returns:
- An iterator of the classes having this property as one of their declared properties
-
listDeclaringClasses
ExtendedIterator<? extends OntClass> listDeclaringClasses(boolean direct)
Answer an iterator of all of the classes in this ontology, such that each returned class has this property as one of its properties in
OntClass.listDeclaredProperties(boolean)
. This simulates a frame-like view of properties and classes; for more details see the RDF frames how-to.- Parameters:
direct
- If true, use only direct associations between classes and properties- Returns:
- An iterator of the classes having this property as one of their declared properties
-
listReferringRestrictions
ExtendedIterator<Restriction> listReferringRestrictions()
Answer an iterator over any restrictions that mention this property as the property that the restriction is adding some constraint to. For example:
<owl:Restriction> <owl:onProperty rdf:resource="#childOf" /> <owl:hasValue rdf:resource="#ian" /> </owl:Restriction>
Note that any such restrictions do not affect the global semantics of this property itself. Restrictions define new class expressions, and the property constraints are local to that class expression. This method is provided as a convenience to assist callers to navigate the relationships in the model.
- Returns:
- An iterator whose values are the restrictions from the local model that reference this property.
