Hi all, I’m wondering about the performance differences between
1) JCasUtil.selectCovered(JCas, Class<T>, AnnotationFS), 2) JCasUtil.selectCovered(JCas, Class<T>, int, int) and 3) JCasUtil.indexCovered(JCas, Class<T>, Class<S>) It is clear that 3) iterates once through the CAS and just returns a map. Once this is done, map access is swift. The Javadoc of 2) states that it is slower than 1). 3) states that it is preferable to 2). Questions: Is 3) also preferable over 2) when there is only one covering annotation or is the performance of 2) and 3) roughly equal then? Main question: Is 3) also quicker than 1) if there are many covering annotations? Use case: I want to iterate through all sentences in paragraphs. Normally, I would use subiterators(), but the known type priority issue could be a problem for me. Should I just use 1)? Or would I still benefit from 3) if I have more than one paragraph? Thank you very much! Best, Erik
