generics: JFSIndexRepository

public interface JFSIndexRepository {

  FSIndex<TOP> getIndex(String label);
  FSIndex<TOP> getIndex(String label, int type);
  AnnotationIndex<Annotation> getAnnotationIndex();
  AnnotationIndex<Annotation> getAnnotationIndex(int type);
  Iterator<FSIndex<Top>> getIndexes();
  FSIterator<TOP> getAllIndexedFS(Type aType);
  FSIterator<TOP> getAllIndexedFS(int aType);
}

Is the above generification correct ?

We could use FeatureStructure instead of TOP, I am not sure
whats better.

Seems to me that TOP is better for JCAS, just like Annotation is
better than AnnotationFS.

I think the generification is correct, because TOP is the JCas version
of the FeatureStructure interface. 

Another note (http://markmail.org/thread/pafkl3luotd3wkfr - toward the
bottom of the thread) suggests additional methods that pass in a class
instance, and then use that to specify the returned type.
