Interface OWLDescriptionVisitor

All Known Implementing Classes:

OWLDescriptionVisitorAdapter

public interface OWLDescriptionVisitor

A Visitor for OWL data structure objects. See Design Patterns, Gamma et. al. p.331 for a detailed description of the Visitor pattern. If you wish to define operations over the data structure (e.g. providing some kind of 3rd party representation of an OWL ontology), then you should implement this interface accordingly. For each concrete class Concrete in the OWLDescription hierarchy, a function visit(Concrete) must be provided.

The expression can then be visited using the accept method.

Use of the Visitor architecture allows us to add application-specific functionality without "tainting" the data structure. Be aware, though, that if the concrete subclasses of OWLDescription change, then the implementors of this interface may need to change accordingly.
