Marshall Schor commented on UIMA-5115:
--------------------------------------
I was thinking of selectCovered. The question I was posing arises in the case
where the type of the bounding FS is a subtype of the index type being
iterated, just opposite to your example.
For instance: selectCovered(Sentence.type, aVeryWideToken), where someone has
(for reasons unknown) constructed a "Token" covering multiple sentences. Here
the question is, do you return items of Sentence and its subtypes, or Token and
its subtypes?
I think the answer is you return Sentence and subtypes; that is, there's no
additional type filtering based on the type of the bounding FS (again, because
it's not needed - if only tokens are wanted, that's more directly expressible
using Token.class as the first argument).
