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.
