Subject [jira] Resolved: (PIG-56) implement Iterable<Tuple> in DataBag
Date Tue, 15 Jan 2008 16:08:34 GMT

Alan Gates resolved PIG-56.
---------------------------

       Resolution: Fixed
    Fix Version/s: 0.1.0

I checked in the changes to DataBag to make it iterable.  I didn't check in the rest, as we
don't need to rewrite existing code.  Thanks to Charlie Groves for contributing this.

> 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.
