Interface SchedulingAwareRunnable

All Superinterfaces:: Runnable

public interface SchedulingAwareRunnable
extends Runnable
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.
