Method Details

superProperties

public Stream<OntObjectProperty> superProperties(boolean direct)

Description copied from interface: OntObjectProperty

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.

Specified by:

superProperties in interface OntObjectProperty

Specified by:

superProperties in interface OntProperty

Specified by:

superProperties in interface OntRelationalProperty

Parameters:

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

Returns:

distinct Stream of object property expressions

See Also:

• OntObjectProperty.propertyChains()

subProperties

public Stream<OntObjectProperty> subProperties(boolean direct)

Description copied from interface: OntObjectProperty

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.

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
