public class RuleServiceImpl
extends Object
implements RuleService, RuntimeRuleService, NodeServicePolicies.OnCreateChildAssociationPolicy, NodeServicePolicies.OnCreateNodePolicy, NodeServicePolicies.OnUpdateNodePolicy, NodeServicePolicies.OnAddAspectPolicy

Rule service implementation.

This service automatically binds to the transaction flush hooks. It will therefore participate in any flushes that occur during the transaction as well.
