@Deprecated public class FederatedFactBase extends fr.inria.rules.dlgpemodel.SentenceImpl implements FactBase
Deprecated.
A factBase made of several FactBases. This storage system assumes that the Predicate of the Atom is enough to determine to which sub-storage-system we need to delegate the queries
