Summary: Order in SelectFS
Key: UIMA-5846
URL: https://issues.apache.org/jira/browse/UIMA-5846
Project: UIMA
Issue Type: Question
Components: Core Java Framework
Reporter: Richard Eckart de Castilho
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()`.
