public class RepositoryModelSet
extends AbstractModelSetImpl

A ModelSet implementation for the OpenRDF (Sesame) 2.0.1 API. 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.

Note: Every Model returned by this implementation should be explicitly closed by the user.
