public abstract class AbstractStatefulJob
extends java.lang.Object
implements org.quartz.StatefulJob

Provides a wrapper around Quartz stateful job. Implementations of this job will never trigger a misfire because the execute method will never throw exceptions back to Quartz. Jobs extending this class are assured by Quartz to never run concurrently within the cluster.
