Package org.opennms.netmgt.eventd

Class DefaultEventHandlerImpl

java.lang.Object

org.opennms.netmgt.eventd.DefaultEventHandlerImpl

All Implemented Interfaces:

EventHandler, org.springframework.beans.factory.InitializingBean

public final class DefaultEventHandlerImpl
extends java.lang.Object
implements org.springframework.beans.factory.InitializingBean, EventHandler

The EventHandler builds Runnables that essentially do all the work on an incoming event. Operations done on an incoming event are handled by the List of injected EventProcessors, in the order in which they are given in the list. If any of them throw an exception, further processing of that event Log is stopped.
