Gilles resolved MATH-804.
-------------------------
Resolution: Fixed
> Make "CurveFitter" a generic class
> ----------------------------------
>
> Key: MATH-804
> URL: https://issues.apache.org/jira/browse/MATH-804
> Project: Commons Math
> Issue Type: Improvement
> Reporter: Gilles
> Assignee: Gilles
> Priority: Trivial
> Fix For: 3.1
>
>
> In order to enhance compile-time robustness, it is proposed to parameterize
> the "CurveFitter" class with the type of the function to be used for the fit,
> i.e.:
> {code}
> public class CurveFitter<T extends ParametricUnivariateFunction> {
> // ...
> public double[] fit(T f, final double[] initialGuess) {
> // ...
> }
> }
> {code}
> Thus enforcing that instances of subclasses like "PolynomialFitter" defined as
> {code}
> public class PolynomialFitter extends
> CurveFitter<PolynomialFunction.Parametric> {
> // ...
> }
> {code}
> cannot call the "fit" method with a different function argument.
