Marshall Schor commented on UIMA-5846:
--------------------------------------
This is probably a mistake on my part when I was copying this from uimaFIT impl
of "selectBetween" - in thinking that the order would be backwards if the
operands were reversed. I'll change this per your suggestion, to just switch
the endpoints, without reversing the direction.
> Order in SelectFS

> Key: UIMA-5846
> URL: https://issues.apache.org/jira/browse/UIMA-5846
> Project: UIMA
> Issue Type: Question
> Components: Core Java Framework
> Affects Versions: 3.0.0SDK
> Reporter: Richard Eckart de Castilho
> Priority: Minor
>
> I'm not sure about the way that order in SelectFS is handled. Naively, I
> would expect that all operations return annotations in index order or in
> reverse index order if `backwards` was called. But for example
> `jcas.select(Sentence.class).between(t1, t2).asList()` returns in normal
> order if `t1 < t2` and in backwards order if `t2 < t1`. While I this seems to
> be a nice touch from the engineering point of view, from a naive user's
> perspective, it seems somewhat surprising to me. Mind that the behavior is
> documented - still I wonder it if is a good idea. If I wanted to have the
> annotations in reverse order, I'd probably try calling
> `jcas.select(Sentence.class).backwards().between(t1, t2).asList()` or maybe
> `jcas.select(Sentence.class).between(t1, t2).backwards().asList()`.
