Examples of org.drools.common.DefaultAgenda

org.drools.common.DefaultAgenda
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 update 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.
