Class DroolsAlarmContext

java.lang.Object

org.opennms.netmgt.alarmd.drools.ManagedDroolsContext

org.opennms.netmgt.alarmd.drools.DroolsAlarmContext

All Implemented Interfaces:

AlarmLifecycleListener

public class DroolsAlarmContext
extends ManagedDroolsContext
implements AlarmLifecycleListener

This class maintains the Drools context used to manage the lifecycle of the alarms. We drive the facts in the Drools context using callbacks provided by the AlarmLifecycleListener. We use a lock updating alarms in the context in order to avoid triggering the rules while an incomplete view of the alarms is present in the working memory.
