public interface StatefulJob extends Job
A marker interface for s that
wish to have their state maintained between executions.
JobDetail
StatefulJob instances follow slightly different rules from
regular Job instances. The key difference is that their
associated is re-persisted after every
execution of the job, thus preserving state for the next execution. The
other difference is that stateful jobs are not allowed to execute
concurrently, which means new triggers that occur before the completion of
the JobDataMapexecute(xx) method will be delayed.
