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
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.
