Subject [jira] [Created] (MATH-786) "hashCode" in "Pair" class
Date Fri, 04 May 2012 13:32:48 GMT
Gilles created MATH-786:
---------------------------

             Summary: "hashCode" in "Pair" class
                 Key: MATH-786
                 URL: https://issues.apache.org/jira/browse/MATH-786
             Project: Commons Math
          Issue Type: Improvement
    Affects Versions: 3.0
            Reporter: Gilles
            Assignee: Gilles
            Priority: Trivial
             Fix For: 3.1


Since "Pair" is supposed to be an immutable class, couldn't we cache the "hashCode" value
at construction? That would supposedly make it more efficient when used in maps.
