---------------------------
Summary: 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.
