I appreciate your comments about the Java collection framework. We've
talked about this on and off, but it never really went anywhere. Is
this something we might want to support in JCas? That would seem like a
good place for it.
Opinions?
I think it is reasonable for FSArray to provide an iterator() method
for both JCAS and CAS. The only reason I could think of for not
wanting to do it in CAS is to keep the CAS APIs as similar as possible
to the C++ CAS APIs. But I think we may want some flexibility there
to do some simple things that make Java programmers' lives easier.
A stickier question is whether FSArray should implement Collection.
It could only be an unmodifiable Collection since arrays are fixed
sized. An advantage of implementing Collection is that users on Java
5 could use the new for(element : collection) construction, but we
still remain 1.4-compatible.
FSList could definitely implement Collection since add() and remove()
can be implemented. (This would be in JCAS, since I don't believe we
have a special Java class for FSList in CAS - it's just treated as an
ordinary FeatureStructure.)
