> Project: UIMA

> Reporter: Richard Eckart de Castilho

> Some of the uimaFIT (J)CasUtil "select" methods work directly on an FSIndex or FSIterator. In those cases, it would be nice if the methods didn't just return a Collection, but some FSCollection<T> in which the iterator() method returns an FSIterator<T>.
> At least in those cases were an AnnotationIndex is used, it would be possible to actually return something that implements Collection<T> and FSIndex<T>, so it can be used in constructors like new ArrayList(...), in modern-style for loops, and for type-save access to the index.
> In those cases were an FSIterator is used because the type searched for is not an annotation, the FSIndex<T> interface is not a good choice, because it contains several methods that cannot be implemented based only on FSIterator.
> So maybe two interfaces: FSCollection<T> based on FSIterator and AnnotationCollection<T> based on FSIndex/AnnotationIndex.
> This mainly exposes more details of UIMA AnnotationIndex via CasUtil. JCasUtil's select method doesn't make a different between FSes that inherit from AnnotationFS or not. Here, the only benefit is getting access to an FSIterator.
