Module org.apache.jena.ontapi

Package org.apache.jena.ontapi.model

Interface OntNegativeAssertion<P extends OntRelationalProperty,V extends org.apache.jena.rdf.model.RDFNode>

Type Parameters:

P - - either object property expression or data property

V - - either OntIndividual or Literal

All Superinterfaces:

org.apache.jena.graph.FrontsNode, OntObject, org.apache.jena.rdf.model.RDFNode, org.apache.jena.rdf.model.Resource

All Known Subinterfaces:

OntNegativeAssertion.WithDataProperty, OntNegativeAssertion.WithObjectProperty

All Known Implementing Classes:

OntNegativePropertyAssertionImpl, OntNegativePropertyAssertionImpl.DataAssertionImpl, OntNegativePropertyAssertionImpl.ObjectAssertionImpl

public interface OntNegativeAssertion<P extends OntRelationalProperty,V extends org.apache.jena.rdf.model.RDFNode>
extends OntObject

Interface representing the Negative Property Assertion abstraction, where predicate (property) is expected to be either ontology data property (R) or object property exception (P). Assuming _:x is a blank node, ai is an individual and v is literal, a Negative Object Property Assertion in Turtle syntax looks like this:

 _:x rdf:type owl:NegativePropertyAssertion ;
 _:x owl:sourceIndividual a1 ;
 _:x owl:assertionProperty P ;
 _:x owl:targetIndividual a2 .
 

In turn, a Negative Data Property Assertion looks like the following:

 _:x rdf:type owl:NegativePropertyAssertion ;
 _:x owl:sourceIndividual a ;
 _:x owl:assertionProperty R ;
 _:x owl:targetValue v .

Method Details

getSource

OntIndividual getSource()

Returns the source individual.

Returns:

OntIndividual

getProperty

P getProperty()

Returns the assertion property.

Returns:

either OntObjectProperty or OntDataProperty

getTarget

V getTarget()

Returns the target node.

Returns:

either OntIndividual or Literal

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
