Description

Forms like cas.getIndexRepository().getAllIndexedFSs(...) return an iterator. It would be nice to be able to use the returned result in an extended for : for (TOP x : cas.getInd... etc).

Add a new set of methods, getIndexedFSs( Type or JCas.class or nothing) to CAS/JCas and FSIndexRepository interfaces, that return Collections, without copying the index arrays, but just using them. Make these copy-on-write style, so subsequent updates to the UIMA indexes won't affect the collection. These can then be used in extended-for loops.

Update internal uses of getAllIndexedFS (which does copy the indexes) to use the new style.
