Subject [jira] Created: (PIG-56) implement Iterable<Tuple> in DataBag
Date Wed, 09 Jan 2008 03:13:33 GMT
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


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.
