> Frequency class Javadoc is ambiguous; need more tests
> -----------------------------------------------------
>
> Key: MATH-258
> URL: https://issues.apache.org/jira/browse/MATH-258
> Project: Commons Math
> Issue Type: Bug
> Reporter: Sebb
> Fix For: 2.0

>
> [Extracted from mailing list so it does not get lost]
> The Javadoc is ambiguous - can one add both int and char to the same instance
> of Frequency?
> Depending on how one reads the class Javadoc, this should be allowed,
> as one can compare "int" and "char" in the same way that one can
> compare "int" and "long" - i.e. both are "comparable". Now "int" and
> "char" are not Comparable, but then neither are "int" and "long".
> I think the Javadoc needs to make the intention clear, and then the
> tests can be enhanced to enforce the documented behaviour.
> At present, there's no check to show what happens when int and char are mixed.
> There are other tests that should be added, to show what is expected when
> mixing different Comparable classes.
