Interface SchedulingAwareRunnable

All Superinterfaces:
  Runnable

    public interface SchedulingAwareRunnable

extends Runnable

Extension of the Runnable interface, adding special callbacks for long-running operations.

This interface closely corresponds to the CommonJ Work interface, but is kept separate to avoid a required CommonJ dependency.

Scheduling-capable TaskExecutors are encouraged to check a submitted Runnable, detecting whether this interface is implemented and reacting as appropriately as they are able to.

Method Detail

### isLongLived

    boolean isLongLived()

  Return whether the Runnable's operation is long-lived (`true`) versus short-lived (`false`).

  In the former case, the task will not allocate a thread from the thread pool (if any) but rather be considered as long-running background thread.

  This should be considered a hint. Of course TaskExecutor implementations are free to ignore this flag and the SchedulingAwareRunnable interface overall.
