Gilles updated MATH-473: ------------------------ Priority: Minor (was: Major) Fix Version/s: (was: 3.1) > Frequency: new option: NON-sorted > --------------------------------- > > Key: MATH-473 > URL: https://issues.apache.org/jira/browse/MATH-473 > Project: Commons Math > Issue Type: Improvement > Affects Versions: 1.0, 1.1, 1.2, 2.0, 2.1 > Reporter: Dan Checkoway > Priority: Minor > Attachments: MATH-473.patch > > > I have a request for enhancement on org.apache.commons.math.stat.Frequency. > I would like to be able to specify that the the backing map NOT be sorted. > Right now it uses TreeMap. I would like to have the option of specifying > that sorting is not important, and would in fact hinder performance, and a > plain old HashMap should be used instead. > i.e. constructor such as: > public Frequency(boolean sorted); > If sorted is true, use a TreeMap. If sorted is false, use a HashMap. Is > this feasible? I'd be happy to contribute a patch if that would help. -- This message is automatically generated by JIRA.
