----------------------------------------------------------------
one idea that might work, but seems messy, is to duplicate both the SelectFSs
and SelectFSs_impl into SelectFSsAnnot and SelectFSsAnnot_impl, the only
difference being the top bound of the generic parameter.
Then, whenever a method in SelectFSs implies a restriction to Annotations (e.g.
"covering", or "at", etc.), have it create a copy of the SelectFSs_impl -> a
new instance of SelectFSsAnnot_impl, and return that. So that from then on,
all the methods will be against the SelectFSsAnnot interface/class.
This would be slightly inefficient (making an extra object, whenever an
Annotation restriction happened). And it remains to be seen, if it can even
work (kind of depends on finding a way to create the instance of
SelectFSsAnnot_impl and pass in the maybe-bound type - don't know if that's
even possible. Do people think it would be worth it? Is there a better way?

> 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();}}
