dk.brics.jwig.persistence.Persistable
A Persistable is an object that can be persisted. Only requirement is that it must contain an ID.

public class CacheInterceptor extends EmptyInterceptor {


    @Override

        while (iterator.hasNext()) {
        Persistable persistable = (Persistable) iterator.next();
        ThreadContext.getDependencyMap().objectUpdated(persistable);
