public class AGVirtualRepository
extends AbstractRepository
implements AGAbstractRepository

A class for virtual repositories, used for working with federations, graph-filtered stores, reasoning stores, and compositions thereof.

Virtual repositories don't reside on disk (their component stores do); they don't have a catalog.

Applications normally create a virtual repository via an AGServer instance.

See Also:

• AGServer.virtualRepository(String)
• AGServer.federate(AGAbstractRepository...)
