Class BedingterAlarmHandler

java.lang.Object

de.ipcon.db.alarm.AlarmHandler

de.ipcon.db.alarm.BOAssociatedAlarmHandler

de.ipcon.db.alarm.BedingterAlarmHandler

All Implemented Interfaces:

BTHandlerI

Direct Known Subclasses:

HinweisHandler, WiedervorlageHandler

public abstract class BedingterAlarmHandler
extends BOAssociatedAlarmHandler

This class handles Alarm instances that need to react to specific events, namely Hinweis and Wiedervorlage. It listens to DBManBOChangeEvents (ok, the AlarmModule does this actually) that occur for objects of classes that the existing (and active) alarm instances are monitoring. If such an event occurs the handler checks if, in the case of HinweisHandler, some Hinweis gets triggered by that event or, in the case of WiedervorlageHandler, some Wiedervorlage gets postponed by it. The event handling is done in its own thread by AlarmModule.EventHandlingRunnable#handleEvent() which in turn calls handleBTFully() here. Should an error occur during handling of the event the possible effects of that event are "lost" and the event will not be handled again (ok, except in one very special case, see comment in handleEvent()). The last error that occurred when checking or triggering/postponing an alarm is always stored on the alarm instance for debugging and can be viewed in the GUI. If some alarm causes too many (currently always 25 errors/h, see Alarm#storeLastError()) errors in a given timespan it automatically gets deactivated and must be manually activated again, hopefully after the cause of the error(s) has been resolved.
