  • Method Details

    • getEntityType

      EntityType<?> getEntityType()
      Gets the entity type for this entity.
      Returns:
      The entity type

    • isType

      default boolean isType(EntityType<?> entityType)
      Tests to see if this entity is of the specified type.
      Parameters:
      entityType - The entity type
      Returns:
      true if this entity is of the specified type, otherwise false.

    • isBuiltIn

      default boolean isBuiltIn()
      Determines if this entity is a built in entity. The entity is a built in entity if it is:
      • a class and the URI corresponds to owl:Thing or owl:Nothing
      • an object property and the URI corresponds to owl:topObjectProperty or owl:bottomObjectProperty
      • a data property and the URI corresponds to owl:topDataProperty or owl:bottomDataProperty
      • a datatype and the IRI is rdfs:Literal or is in the OWL 2 datatype map or is rdf:PlainLiteral
      • an annotation property and the URI is in the set of built in annotation property URIs, i.e. one of:
        • rdfs:label
        • rdfs:comment
        • rdfs:seeAlso
        • rdfs:isDefinedBy
        • owl:deprecated
        • owl:priorVersion
        • owl:backwardCompatibleWith
        • owl:incompatibleWith
      Returns:
      true if this entity is a built in entity, or false if this entity is not a builtin entity.

    • toStringID

      String toStringID()
      Returns:
      a string representation that can be used as the ID of this entity. This is the toString() representation of the IRI

    • accept

      void accept(OWLEntityVisitor visitor)
      Parameters:
      visitor - visitor

    • accept

      <O> O accept(OWLEntityVisitorEx<O> visitor)
      Type Parameters:
      O - visitor return type
      Parameters:
      visitor - visitor
      Returns:
      visitor return value

    • isAnonymous

      default boolean isAnonymous()
      Specified by:
      isAnonymous in interface IsAnonymous
      Returns:
      true if this object is anonymous, false otherwise. For example, class expressions are anonymous while class entities are not (they have an IRI); OWLNamedIndividual instances are named, OWLAnonymousIndividual instances are anonymous. An ontology is anonymous if it does not have an ontology IRI. In this case, getOntologyID().getOntologyIRI() will return an empty optional.
