Interface OntClass.CollectionOf<O extends OntObject>

Type Parameters:
O - a OntObject component type
All Superinterfaces:
org.apache.jena.graph.FrontsNode, OntClass, OntObject, org.apache.jena.rdf.model.RDFNode, org.apache.jena.rdf.model.Resource
All Known Subinterfaces:
OntClass.IntersectionOf, OntClass.OneOf, OntClass.UnionOf
All Known Implementing Classes:
OntClassImpl.IntersectionOfImpl, OntClassImpl.OneOfImpl, OntClassImpl.QLIntersectionOfImpl, OntClassImpl.RLIntersectionOfImpl, OntClassImpl.RLOneOfImpl, OntClassImpl.RLUnionOfImpl, OntClassImpl.UnionOfImpl
Enclosing interface:
OntClass
public static interface OntClass.CollectionOf<O extends OntObject> extends OntClass
An abstract class expression that unites class expressions consisting of multiple components. There are three kinds of such expressions: OntClass.UnionOf, OntClass.IntersectionOf and OntClass.OneOf.

  • Method Details

    • components

      default Stream<O> components()
      Lists all allowed components of the collection. Note that the returned values are not necessarily the same as RDFNodeList.members() output: some profiles (e.g., OWL2 QL) impose some restrictions.
      Returns:
      a Stream of Os

    • 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)

    • getList

      RDFNodeList<O> getList()
      Gets an unmodifiable []-list with items of the type E
      Returns:
      RDFNodeList
