public @interface TriggerWhenEmpty
Marker annotation a processor implementation can use to indicate that the
processor should still be triggered even when it has no data in its work
queue. By default, processors which have no non-self incoming edges will be
triggered even if there is no work in its queue. However, processors that
have non-self incoming edges will only be triggered if they have work in
their queue or they present this annotation.
