DefaultAgenda (Drools 4.0.0.11754MR2 API) - JBoss RULES 4.0.0.11754MR2 API 英文版文档

org.drools.common
Class DefaultAgenda

java.lang.Object
  org.drools.common.DefaultAgenda

All Implemented Interfaces:

Serializable, Agenda, InternalAgenda

public class DefaultAgenda
extends Object
implements Serializable, InternalAgenda

Rule-firing Agenda.

Since many rules may be matched by a single assertObject(...) all scheduled actions are placed into the Agenda.

While processing a scheduled action, it may modify or retract objects in other scheduled actions, which must then be removed from the agenda. Non-invalidated actions are left on the agenda, and are executed in turn.
