Thanks Edson for fixing the getQueryResults() method in JBRULES-539.
I found something interesting I'd like to bring under discussion:
WorkingMemory.getQueryResults() returns null when:
- no such query exists in the drl's. I would have expected an
IllegalArgumentException, in the spirit of fail-fast,
but it's not that big a deal.
- but it also returns null when the query has 0 results.
I would have expected a QueryResults instance with .size() == 0.
It seems inconsistent with WorkingMemory.getObjects(X.class) which does
return an empty list, instead of null.
[tested on the branch for 3.0.x for Rete]
What do you think?
