Benjamin Reed commented on PIG-56:
----------------------------------
+1 Excellent patch. I also agree that the code is much more readable using the
foreach construct, so I think we should integrate that update as well.
> implement Iterable<Tuple> in DataBag
> ------------------------------------

> Key: PIG-56
> URL: https://issues.apache.org/jira/browse/PIG-56
> Project: Pig
> Issue Type: Improvement
> Reporter: Charlie Groves
> Priority: Minor
> Attachments: iterable_databag.patch
>
>
> Now that DataBag has an iterator method, it can implement Iterable with no
> other changes. This would allow bags to be used in a foreach loop like
> for(Tuple t : bag) {
> // do something with t
> }
> The attached patch has DataBag implement iterable and converts all bag
> iterator usages in pig to use foreach loops.
