## 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.

    All Methods Instance Methods Abstract Methods

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

    - #### 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.
