Neil Roeth commented on MATH-742:
---------------------------------
I'm kind of surprised at this result. One developer out of three objected, and
that's a "consensus"? That developer basically said this class should only be
Serialized if X, Y and Z were true. I responded that yes, indeed, it was
precisely X,Y and Z that were true and in fact were what led to my request.
I'd have thought that, all objections having been answered, it would have been
a done deal then. Particularly since PolynomialFunction, a class in the same
package, is already Serializable. Instead, "Won't Fix"? What objections were
raised that were not answered?
Luc, the work arounds you propose are poorer practice than using Serializable
exactly as it was intended. The work arounds both boil down to "implement
serialization of PolynomialSplineFunction through home grown custom code
instead of simply adding the Java standard 'implements Serializable'". That is
not a better solution, so I am going to keep my locally customized version of
the class and hope you someday change your mind.

> Key: MATH-742
> URL: https://issues.apache.org/jira/browse/MATH-742
> Project: Commons Math
> Issue Type: Improvement
> Affects Versions: 2.2
> Reporter: Neil Roeth
> Priority: Minor
> Attachments: PolynomialSplineFunction.java
>
>
> PolynomialSplineFunction is not Serializable, while the very similar
> PolynomialFunction class in the same package is. All that needs to be done is
> to add the import:
> {{import java.io.Serializable;}}
> and change this:
> {{public class PolynomialSplineFunction implements
> DifferentiableUnivariateRealFunction}}
> to this:
> {{public class PolynomialSplineFunction implements
> DifferentiableUnivariateRealFunction, Serializable}}
> I made exactly that modification to a local copy and it serialized
> successfully. Before the change, I got serialization errors.
> Thanks.
