All Implemented Interfaces:

Cloneable, OWLObject, Serializable

public abstract class OWLObjectImpl

extends Object

implements Cloneable, Serializable, OWLObject

A top level class for the kinds of things that are found in Ontologies. Each OWLObject knows about the OWLDataFactory that was used to create it. OWLObjects also accept visits from OWLObjectVisitor. The use of the Visitor pattern (see Design Patterns, Gamma et. al. p.331) allows us to extend the functionality of the data structures without having to alter the underlying implementation.
