[jira] [Created] (UIMA-6292) selectCovering is slow

Richard Eckart de Castilho created UIMA-6292:
------------------------------------------------

             Summary: selectCovering is slow
                 Key: UIMA-6292
                 URL: https://issues.apache.org/jira/browse/UIMA-6292
             Project: UIMA
          Issue Type: Bug
          Components: uimaFIT
            Reporter: Richard Eckart de Castilho
            Assignee: Richard Eckart de Castilho
             Fix For: 2.6.0uimaFIT, 3.2.0uimaFIT


The uimaFIT selectCovering takes much longer than even a naive full index scan with an annotation predicate.

Reason seems to be a quite unnecessary condition on the type of the annotations which is checked in a loop. This can be avoided by obtaining an index of the proper type and iterating over that.
