All known Subclasses: com.hp.hpl.jena.reasoner.rulesys.impl.LPRuleStore,
| RuleStore | | public class RuleStore (Code) | | Indexes a collection of rule. The currently implementation is
a crude first version aimed at supporting the backchaining
interpreter. It only indexes on predicate.
The rules are normalized to only contain a single head element
by duplicating any multi headed rules.
