Re: JCas setup in uima v3. The basic answer is, yes, there's probably a
similar overhead, although this would need to be measured.
So, you may want to not define user JCas types, if this
one-time-at-startup-loading-of-JCas-classes is too slow. If you don't define
user JCas types, then the code runs using only the built-in JCas classes (like
Annotation, and TOP), which would still need to be loaded. For instance, all
Annotations would end up being instantiated as variants of the Annotation type.
So you could get the same efficiencies (of not loading lots of user-defined
types), by using the form mycas.<Annotation>selectFSs.....

> URL: https://issues.apache.org/jira/browse/UIMA-6153
> Project: UIMA
> Issue Type: Improvement
> Components: UIMA
> Affects Versions: 3.1.1SDK
> Reporter: Richard Eckart de Castilho
> Priority: Major
>
> The following code does not compile because select.covering() uses TOP
> instead of AnnotationFS as the generic type. Consequently, getBegin() and
> getEnd() are not available on the "s" used in the filter expressions. But
> since covering() only makes sense for annotations, binding the generic type
> to TOP doesn't seem to make much sense:
> {{return aCas.select(getType(aCas, Sentence.class)).covering(aBegin1,
> aBegin1)}}
> {{ .filter(s -> s.getBegin() <= aBegin1 && aBegin1 < s.getEnd())}}
> {{ .filter(s -> s.getBegin() <= aBegin2 && aBegin2 <
> s.getEnd()).findFirst()}}
> {{ .isPresent();}}
