/**
 * A marker interface for {@link org.quartz.JobDetail} s that
 * wish to have their state maintained between executions.
 * 
 * 
 * StatefulJob instances follow slightly different rules from
 * regular Job instances. The key difference is that their
 * associated {@link JobDataMap} 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 execute(xx) method will be delayed.
 * 
 * 
 * @see DisallowConcurrentExecution
 * @see PersistJobDataAfterExecution
 * 
 * @see Job
 * @see JobDetail
 * @see JobDataMap
 * @see Scheduler
 * 
 *
 * @deprecated use DisallowConcurrentExecution and/or PersistJobDataAfterExecution annotations instead.
