Subject [jira] [Created] (DATAFU-42) Simplify BagGroup output
Date Mon, 28 Apr 2014 14:42:16 GMT
Sam Steingold created DATAFU-42:
-----------------------------------

             Summary: Simplify BagGroup output
                 Key: DATAFU-42
                 URL: https://issues.apache.org/jira/browse/DATAFU-42
             Project: DataFu
          Issue Type: Improvement
            Reporter: Sam Steingold


{{BagGroup}} keeps the redundant {{group}} information in its output.
E.g., see [DATAFU-38]:
{code}
(1,{(b,1),(a,2)},{(B,{(B,3)}),(A,{(A,1),(A,2)})})
(2,{(c,1),(b,2)},{(B,{(B,3),(B,5)}),(A,{(A,1),(A,2)}),(C,{(C,4),(C,6)})})
{code}
can be
{code}
(1,{(b,1),(a,2)},{(B,{3}),(A,{1,2})})
(2,{(c,1),(b,2)},{(B,{3,5}),(A,{1,2}),(C,{4,6})})
{code}
without loss of information

Given that the bug [DATAFU-38] rendered this function quite useless and it was fixed just
last week, I think {{BagGroup}} has not been used before, so this backward-incompatible change
will not break any existing code.
