createAnonymousIndividual

public static OntIndividual.Anonymous createAnonymousIndividual(org.apache.jena.rdf.model.RDFNode node)

classes

public Stream<OntClass> classes(boolean direct)

Returns a Stream of all class-types, including their super-classes if the parameter direct is false.

Specified by:

classes in interface OntIndividual

Parameters:

direct - if true returns only direct types

Returns:

a Stream of all class-types

See Also:

• OntIndividual.classes()
• OntClass.superClasses(boolean)

hasOntClass

public boolean hasOntClass(OntClass clazz,
 boolean direct)

Description copied from interface: OntIndividual

Answers true if the given class is in the class-type closure.

Specified by:

hasOntClass in interface OntIndividual

Parameters:

clazz - OntClass to test

direct - see OntIndividual.classes(boolean)

Returns:

true if the specified class found

sameIndividuals

public Stream<OntIndividual> sameIndividuals()

Description copied from interface: OntIndividual

Lists all same individuals. The pattern to search for is ai owl:sameAs aj, where ai is this individual.

Specified by:

sameIndividuals in interface OntIndividual

Returns:

addSameAsStatement

public OntStatement addSameAsStatement(OntIndividual other)

Description copied from interface: OntIndividual

Adds a same individual reference.

Specified by:

addSameAsStatement in interface OntIndividual

Parameters:

other - OntIndividual, not null

Returns:

OntStatement to allow subsequent annotations adding

See Also:

• OntIndividual.addSameIndividual(OntIndividual)
• OntIndividual.removeSameIndividual(Resource)
• 9.6.1 Individual Equality

removeSameIndividual

public OntIndividual removeSameIndividual(org.apache.jena.rdf.model.Resource other)

Description copied from interface: OntIndividual

Removes a same individual statement for this and specified individuals, including the statement's annotation. No-op in case no same individuals are found. Removes all triples with the predicate owl:sameAs if null is specified.

Specified by:

removeSameIndividual in interface OntIndividual

Parameters:

See Also:

• OntIndividual.addSameAsStatement(OntIndividual)
• OntIndividual.addSameIndividual(OntIndividual)

differentIndividuals

public Stream<OntIndividual> differentIndividuals()

Description copied from interface: OntIndividual

Lists all different individuals. The pattern to search for is thisIndividual owl:differentFrom otherIndividual, where otherIndividual is one of the returned.

Specified by:

differentIndividuals in interface OntIndividual

Returns:

Stream of OntIndividuals

See Also:

• OntDisjoint.Individuals

addDifferentFromStatement

public OntStatement addDifferentFromStatement(OntIndividual other)

Description copied from interface: OntIndividual

Adds a owl:differentFrom individual statement.

Specified by:

addDifferentFromStatement in interface OntIndividual

Parameters:

other - OntIndividual, not null

Returns:

OntStatement to provide the ability to add annotations subsequently

See Also:

• OntIndividual.addDifferentIndividual(OntIndividual)
• OntIndividual.removeDifferentIndividual(Resource)
• OntDisjoint.Individuals

removeDifferentIndividual

public OntIndividual removeDifferentIndividual(org.apache.jena.rdf.model.Resource other)

Description copied from interface: OntIndividual

Removes a different individual statement for this and specified individuals, including the statement's annotation. No-op in case no different individuals are found. Removes all triples with the predicate owl:differentFrom if null is specified.

Specified by:

removeDifferentIndividual in interface OntIndividual

Parameters:

other - Resource or null to remove all different individuals

Returns:

this instance to allow cascading calls

See Also:

• OntIndividual.addDifferentFromStatement(OntIndividual)
• OntIndividual.addDifferentIndividual(OntIndividual)
• OntDisjoint.Individuals

public org.apache.jena.util.iterator.ExtendedIterator<OntClass> listClasses()

Lists all right parts from class assertion statements where this individual is at subject position.

Returns:

ExtendedIterator over all direct class-types

isLocal

public boolean isLocal()

Overrides:

isLocal in class OntObjectImpl

Returns:

true if the root statement belongs to the base graph

listClassAssertions

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

Lists all class assertion statements.

Returns:

ExtendedIterator over all class assertions.

negativeAssertions

public Stream<OntNegativeAssertion> negativeAssertions()

Description copied from interface: OntIndividual

Lists all negative property assertions for this individual.

Specified by:

negativeAssertions in interface OntIndividual

Returns:

Stream of negative property assertions

listNegativeAssertions

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

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
