org.evolizer.ontology.exporter.reflection.RDF2Visitor

This class fetches all the semantical descriptions from a instance of any given class. For that, it crawls all the {@link rdf}-annotated�methods of an instance of a {@link rdf}-annotated class and builds a {@link Collection}of {@link Statement}s describing its relationships to other objects. The current instance is usually considered to be the subject in the <subject, predicate, object> triple, its {@link rdf}-annotated methods are establishing the predicates and their return values the objects. There's a special case whenever a Java Class is used to model a association between two entities but does not represent a concept itself (consider e.g. instances of a class Relationship that connects, e.g., two Person instances, instead of a method getRelatedPerson() in Person). The class is then not considered to be a subject, but rather a predicate, and the visitor looks for methods annotated with {@link subject}and {@link object} to be able make a complete statement. @author wuersch
