Jeff Zhang reassigned PIG-1166: ------------------------------- Assignee: Jeff Zhang > A bit change of the interface of Tuple & DataBag ( make the set and append > method return this) > ---------------------------------------------------------------------------------------------- > > Key: PIG-1166 > URL: https://issues.apache.org/jira/browse/PIG-1166 > Project: Pig > Issue Type: Improvement > Reporter: Jeff Zhang > Assignee: Jeff Zhang > Priority: Minor > > When people write unit test for UDF, they always need to build a tuple or > bag. If we change the interface of Tuple and DataBag, make the set and > append method return this, it can decrease the code size. e.g. Now people > have to write the following code to build a Tuple: > {code} > Tuple tuple=TupleFactory.getInstance().newTuple(3); > tuple.set(0,"item_0"); > tuple.set(1,"item_1"); > tuple.set(2,"item_2"); > {code} > If we change the interface, make the set and append method return this, we > can rewrite the above code like this: > {code} > Tuple tuple=TupleFactory.getInstance().newTuple(3); > tuple.set(0,"item_0").set(1,"item_1").set(2,"item_2"); > {code} > This interface change won't have back compatibility problem and I think > there's no performance problem too. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
