Jonathan Coveney commented on PIG-2724:
---------------------------------------
- Thanks for the heads up on the javadoc
- Yeah, I was thinking about pushing in hashCode as well, but I don't like the
idea of pushing in hashCode if we don't push in compareTo as well... either we
have default behavior for both, or neither, IMHO.
- I will have DefaultTuple override it and do what it used to do, and leave
AbstractTuple's as the general.
- AbstractTypeAwareTuple let's you merge together AbstractTuple+TypeAwareTuple
interface. It feels cleaner than forcing classes to do that themselves?

> I mean yeah, you can do the following:
> {code}
> for (Object o : t.getAll()) {
> doStuff(o);
> }
> {code}
> But I don't even think that should be necessary. I think the following should
> work:
> {code}
> for (Object o : t) {
> doStuff(o);
> }
> {code}
> It's a shame we can't give a default implementation (I either shake my fist
> that this won't be possible until Java 8 OR that Tuple is an interface and
> not an abstract class). Either way, I even added test! WOAH.
> Thoughts?
