Method Details

subProperties

Stream<OntObjectProperty> subProperties(boolean direct)

Answers a Stream over all the properties that are declared to be sub-properties of this property. Each element of the Stream will have the same type as this property instance: if it is datatype property the method will return only data properties, etc. The parameter direct controls selectivity over the properties that appear in the Stream. Consider the following scenario:

  :D rdfs:subPropertyOf :C .
  :C rdfs:subPropertyOf :A .
  :B rdfs:subPropertyOf :A .
 

(so A has two sub-properties, B and C, and C has sub-property D) In a raw model, with no inference support, listing the sub-property of A will answer B and C. In an inferencing model, rdfs:subPropertyOf is known to be transitive, so the sub-properties iterator will include D. The direct sub-properties are those members of the closure of the subPropertyOf relation, restricted to properties that cannot be reached by a longer route, i.e., the ones that are directly adjacent to the given root. Thus, the direct sub-properties of A are B and C only, and not D - even in an inferencing graph. Note that this is different from the entailments from the raw graph. Suppose we add to this example:

   :D rdfs:subPropertyOf :A.
 

Now, in the raw graph, A has sub-property C. But the direct sub-properties of A remain B and C, since there is a longer path A-C-D that means that D is not a direct sub-property of A. The assertion in the raw graph that A has sub-property D is essentially redundant, since this can be inferred from the closure of the graph.

Specified by:

subProperties in interface OntProperty

Specified by:

subProperties in interface OntRelationalProperty

Parameters:

direct - boolean if true answers the directly adjacent properties in the sub-property relation: i.e., eliminate any properties for which there is a longer route to reach that parent under the sub-property relation

Returns:

distinct Stream of object property expressions

See Also:

• propertyChains()

superProperties

Stream<OntObjectProperty> superProperties(boolean direct)

Answers a Stream over all the properties that are declared to be super-properties of this property. Each element of the Stream will have the same type as this property instance: if it is datatype property the method will return only data properties, etc. The parameter direct controls selectivity over the properties that appear in the Stream. Consider the following scenario:

  :A rdfs:subPropertyOf :B .
  :A rdfs:subPropertyOf :C .
  :C rdfs:subPropertyOf :D .
  

(so A has super-property B and C, and C has super-property D) In a raw model, with no inference support, listing the super-property of A will answer B and C. In an inferencing model, rdfs:subPropertyOf is known to be transitive, so the super-property iterator will include D. The direct super-properties are those members of the closure of the inverse-subPropertyOf relation, restricted to properties that cannot be reached by a longer route, i.e., the ones that are directly adjacent to the given root. Thus, the direct super-property of A are B and C only, and not D - even in an inferencing graph. Note that this is different from the entailments from the raw graph. Suppose we add to this example:

   :A rdfs:subPropertyOf :D .
 

Now, in the raw graph, A has super-property B, C, D. But the direct super-property of A remain only B and C, since there is a longer path A-C-D that means that D is not a direct super-property of A. The assertion in the raw graph that A has super-property D is essentially redundant, since this can be inferred from the closure of the graph.

 :Labrador rdfs:subClassOf :Dog .
 :hasDog rdf:type owl:ObjectProperty .

this instance to allow cascading calls

removeInverseProperty

default OntObjectProperty removeInverseProperty(org.apache.jena.rdf.model.Resource other)

Removes the statement with the predicate owl:inverseOf and the given object property as an object. If the argument is null, all owl:inverseOf statements will be removed for this object property. No-op in case there is no owl:inverseOf statements.

Parameters:

other - OntObjectProperty or null to remove all owl:inverseOf statements

Returns:

this instance to allow cascading calls

• addInverseProperty(OntObjectProperty)

setFunctional

default OntObjectProperty setFunctional(boolean functional)

Adds or removes owl:FunctionalProperty declaration for this property according to the given boolean flag. Note: the statement is removed along with all its annotations.

Specified by:

setFunctional in interface OntRelationalProperty

Parameters:

functional - true if should be functional

Returns:

this instance to allow cascading calls

See Also:

• OntRelationalProperty.addFunctionalDeclaration()

inverseProperty

default Optional<OntObjectProperty> inverseProperty()

Finds the first object property from the right part of the statements _:x owl:inverseOf PN or P1 owl:inverseOf P2. Here _:x is an anonymous object property expression (i.e. Inverse Object Property), PN is a named object property and P1, P2 are any object property expressions. What exactly is the first statement is defined at the level of model; in general, it is unpredictable.

Returns:

Optional of OntObjectProperty

• inverseProperties()
• OntObjectProperty.Inverse.getDirect()

isInverseFunctional

default boolean isInverseFunctional()

Returns:

true iff it is an inverse functional property

setInverseFunctional

default OntObjectProperty setInverseFunctional(boolean inverseFunctional)

Adds or removes the P rdf:type owl:InverseFunctionalProperty statement depending on the given flag and returns this property to allow cascading calls. Note: the statement is removed along with all its annotations.

Parameters:

inverseFunctional - if true the property must be inverse-functional

Returns:

this instance to allow cascading calls

See Also:

• addInverseFunctionalDeclaration()

isTransitive

default boolean isTransitive()

Returns:

true iff it is a transitive property

setTransitive

default OntObjectProperty setTransitive(boolean transitive)

Adds or removes the P rdf:type owl:TransitiveProperty statement depending on the given flag and returns this property to allow cascading calls. Note: the statement is removed along with all its annotations.

Parameters:

transitive - if true the property must be transitive

Returns:

this instance to allow cascading calls

See Also:

• addTransitiveDeclaration()

isSymmetric

default boolean isSymmetric()

Returns:

true iff it is a symmetric property

setSymmetric

default OntObjectProperty setSymmetric(boolean symmetric)

Adds or removes the P rdf:type owl:SymmetricProperty statement depending on the given flag and returns this property to allow cascading calls. Note: the statement is removed along with all its annotations.

Parameters:

symmetric - if true the property must be symmetric

Returns:

this instance to allow cascading calls

See Also:

• addSymmetricDeclaration()

isAsymmetric

default boolean isAsymmetric()

Returns:

true iff it is an asymmetric property

setAsymmetric

default OntObjectProperty setAsymmetric(boolean asymmetric)

Adds or removes the P rdf:type owl:AsymmetricProperty statement depending on the given flag and returns this property to allow cascading calls. Note: the statement is removed along with all its annotations.

Parameters:

asymmetric - if true the property must be asymmetric

Returns:

this instance to allow cascading calls

See Also:

• addAsymmetricDeclaration()

isReflexive

default boolean isReflexive()

Returns:

true iff it is a reflexive property

setReflexive

default OntObjectProperty setReflexive(boolean reflexive)

Adds or removes the P rdf:type owl:ReflexiveProperty statement depending on the given flag and returns this property to allow cascading calls. Note: the statement is removed along with all its annotations.

Parameters:

reflexive - if true the property must be reflexive

Returns:

this instance to allow cascading calls

See Also:

• addReflexiveDeclaration()

isIrreflexive

default boolean isIrreflexive()

Returns:

true iff it is an irreflexive property

setIrreflexive

default OntObjectProperty setIrreflexive(boolean irreflexive)

Adds or removes the P rdf:type owl:IrreflexiveProperty statement depending on the given flag and returns this property to allow cascading calls. Note: the statement is removed along with all its annotations.

Parameters:

irreflexive - if true the property must be irreflexive

Returns:

this instance to allow cascading calls

See Also:

• addIrreflexiveDeclaration()

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
