Class AGVirtualRepository

java.lang.Object
  com.franz.agraph.repository.AGVirtualRepository

All Implemented Interfaces:

AGAbstractRepository, Closeable, Repository

public class AGVirtualRepository
extends Object
implements AGAbstractRepository, Closeable

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...)
