Subject [jira] Commented: (PIG-56) implement Iterable<Tuple> in DataBag
Date Wed, 09 Jan 2008 21:49:33 GMT

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.

> 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.
