Constructor Details

OntAnnotationImpl

public OntAnnotationImpl(org.apache.jena.graph.Node n,
 org.apache.jena.enhanced.EnhGraph m)

Method Details

createAnnotation

public static OntAnnotation createAnnotation(org.apache.jena.rdf.model.Model model,
 org.apache.jena.rdf.model.Statement base,
 org.apache.jena.rdf.model.Resource type)

Creates a new annotation b-node resource with the given type and base statement.

Parameters:

model - Model

base - base ont-statement

type - owl:Axiom or owl:Annotation

Returns:

OntAnnotation the anonymous resource with a specified type.

listRelatedStatements

public static org.apache.jena.util.iterator.ExtendedIterator<OntStatement> listRelatedStatements(OntAnnotation annotation)

Lists annotation assertions plus sub-annotation root statements.

Parameters:

annotation - OntAnnotation

Returns:

ExtendedIterator of OntStatements

listSpec

public org.apache.jena.util.iterator.ExtendedIterator<OntStatement> listSpec()

Description copied from class: OntObjectImpl

Lists all object's characteristic statements according to its OWL2 specification.

Overrides:

listSpec in class OntObjectImpl

Returns:

ExtendedIterator of OntStatements

getBase

public OntStatement getBase()

Description copied from interface: OntAnnotation

Returns the base statement, i.e. statement to which this bulk-annotation is attached. In the example above it is the statement <Class> rdf:type owl:Class. Notes: Starting v.2.0.0 the presence of this statement in the Graph does not require anymore. The result could be null in the special case of anonymous resource, e.g. when rdf:type is owl:AllDisjointClasses, see class description.

Specified by:

getBase in interface OntAnnotation

Returns:

OntStatement, possibly null

listAssertions

public org.apache.jena.util.iterator.ExtendedIterator<OntStatement> listAssertions()

Description copied from class: OntObjectImpl

Returns an iterator over object's annotation property assertions. The annotation assertion is a statements with an annotation property as predicate.

Overrides:

listAssertions in class OntObjectImpl

Returns:

ExtendedIterator of OntStatements

See Also:

• OntObjectImpl.assertions()

listAnnotations

public org.apache.jena.util.iterator.ExtendedIterator<OntStatement> listAnnotations()

Description copied from class: OntObjectImpl

Lists all related annotation assertions.

Overrides:

listAnnotations in class OntObjectImpl

Returns:

ExtendedIterator of OntStatements

See Also:

• OntObjectImpl.annotations()

descendants

public Stream<OntAnnotation> descendants()

Description copied from interface: OntAnnotation

Lists all descendants of this ont-annotation resource. The resulting resources must have owl:Annotation type and this object on predicate owl:annotatedSource. The method OntAnnotation.parent() called on descendants must return the annotation equals to this.

Specified by:

descendants in interface OntAnnotation

Returns:

Stream of OntAnnotations

listDescendants

public org.apache.jena.util.iterator.ExtendedIterator<OntAnnotation> listDescendants()

Returns an iterator over all descendants of this ont-annotation resource.

Returns:

ExtendedIterator of OntAnnotations

addAnnotation

public OntStatement addAnnotation(OntAnnotationProperty property,
 org.apache.jena.rdf.model.RDFNode value)

Description copied from class: OntObjectImpl

Adds an annotation assertion. It could be expanded to a bulk form by adding sub-annotation.

Specified by:

addAnnotation in interface OntAnnotation

Specified by:

addAnnotation in interface OntObject

Overrides:

addAnnotation in class OntObjectImpl

Parameters:

property - OntAnnotationProperty, Named annotation property.

value - RDFNode the value: uri-resource, literal or anonymous individual.

Returns:

OntStatement for newly added annotation

See Also:

• OntStatement.addAnnotation(OntAnnotationProperty, RDFNode)

objectType

public Class<? extends OntObject> objectType()

Description copied from class: OntObjectImpl

Gets a public ont-object type identifier.

Specified by:

objectType in interface OntObject

Overrides:

objectType in class OntObjectImpl

Returns:

Class, the actual type of this object

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

• RDFNode.canAs(Class)
