Method Details

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
