Subject [jira] Commented: (MATH-448) Frequency get number of unique values
Date Tue, 07 Dec 2010 03:09:09 GMT


Patrick Meyer commented on MATH-448:

All right, maybe I have it right this time. I used Eclipse to generate the patch and it seems
to have the right information in it. The latest path file (MATH-448.patch) is now attached
to this issue.

> It is often useful to know the number of unique elements in a frequency table. Could
you add a simple method that returns the size of freqTable. It seems like it would be as simple

> {code}
> Given that freqTable is private, there is no way to extend the class and add this method.
