In looking at uimaFIT's select, and some of the discussion on the issue
tracking, I'm wondering if it would better to have the things that support the
use cases:
for (Token t : select(jcas, Token.class) {
return an Iterable, instead of a Collection.
That would drop the methods in Collection except for iterator(). These methods,
for the most part, deal with things that CAS iterators don't have an easy
ability to deal with, or can't implement due to logical differences between the
CAS/Indexes/Iterators and Collections. These methods are:
- size (requires iterating and counting all the elements)
- add, addAll (not supported, instead, add to the CAS, and choose to index or
not)
- remove, removeAll, clear (not supported, but remove-from-all-indexes is)
- contains, containsAll, retainAll (not supported because depends on a
particular index's definition of equal)
The only method of Collection that seems like it could be useful (besides, of
course, iterator) for UIMA iterators is toArray, and the general object methods
toString, equals, and hashCode.
