Collection Reader Progress

What to return from method Progress of CasCollectionReader_ImplBase
when I do not know the total number of artifacts?

Good afternoon,

I've used this.

public Progress[] getProgress() {
  return new Progress[] { new
ProgressImpl(number_of_completed_artifacts, -1, Progress.ENTITIES,
true) };
}

At least it does compile and run. Is it semantically correct, too?

Cheers,
Armin

Yes, is optional, but applications that use the information typically treat
-1 as "unknown"

Hi Armin,
Just return null. I rarely implement that method...
