[jira] [Commented] (UIMA-5828) Unable to fetch preceding annotations in order

["Marshall Schor (JIRA)" <de...@uima.apache.org>]

    [ https://issues.apache.org/jira/browse/UIMA-5828?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16547134#comment-16547134 ] 

Marshall Schor commented on UIMA-5828:
--------------------------------------

I missed the bit in the impl of uimaFIT's preceding, where it reversed the result at the end...   I'll change this to match uimaFIT's ordering, and also update the documentation and the javadocs.

> uimaFIT has a call `selectPreceding` which returns the n annotations before the specified annotations in normal order.
> This seems to be quite difficult to replicate using UIMAv3 SelectFS:
> {code:java}
>     Annotation a = new Annotation(this.jCas, 0, 1);
>     Annotation b = new Annotation(this.jCas, 2, 3);
>     Annotation c = new Annotation(this.jCas, 4, 5);
>     for (Annotation ann : Arrays.asList(a, b, c)) {
>       ann.addToIndexes();
>     }
>     // uimaFIT: Arrays.asList(a, b), selectPreceding(this.jCas, Annotation.class, c, 2));
>     // Produces reverse order
>     assertEquals(Arrays.asList(a, b), jCas.select(Annotation.*class*).preceding(c).limit(2).asList());
>     // Produces: java.lang.IllegalArgumentException: Strict requires BoundsUse.coveredBy
>     assertEquals(Arrays.asList(a, b), jCas.select(Annotation.class).at(c).shifted(-2).limit(2).asList());
> {code}
