Class Scheduler

java.lang.Object

org.jboss.dashboard.scheduler.Scheduler

@ApplicationScoped
@Named(value="scheduler")
public class Scheduler
extends Object

Task scheduler component. Implementation details:

• It uses internally an instance of java.util.concurrent.ScheduledThreadPoolExecutor which provides a thread pool and the delayed task execution capability.
• Fully transactional. Because it's integrated with the Hibernate transaction manager. So all the scheduler operations are committed only if the underlying transaction completes successfully.
