Interface SchedulingAwareRunnable

All Superinterfaces:

java.lang.Runnable

All Known Implementing Classes:

DefaultMessageListenerContainer.AsyncMessageListenerInvoker

public interface SchedulingAwareRunnable
extends java.lang.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.

Since:

2.0

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.
