public class RepositoryModel
extends AbstractLockingModel
implements Model

Implementation of the RDF2Go model interface for an OpenRDF Repository. Note that RepositoryModel and RepositoryModelSet only work well together because they both keep their RepositoryConnections in auto-commit mode. This cannot be changed by the user. Do mass-updates using update(Diff), addAll(Iterator) or removeAll(Iterator), then the current connection will be used in non-autocommit mode and commited, including a rollback when it fails.
