Subject [jira] Created: (MATH-448) Frequency get number of unique values
Date Wed, 01 Dec 2010 15:12:11 GMT
Frequency get number of unique values
-------------------------------------

                 Key: MATH-448
                 URL: https://issues.apache.org/jira/browse/MATH-448
             Project: Commons Math
          Issue Type: New Feature
            Reporter: Patrick Meyer
            Priority: Minor


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 as:

{code}
public int getUniqueCount(){
     return freqTable.size();
}
{code}

Given that freqTable is private, there is no way to extend the class and add this method.
Thanks!
