Subject Re: [math][proposal] Drop serialization from selected classes
Date Tue, 01 Jun 2004 20:34:25 GMT
I need to clarify a detail I didn't fully grok when we started this 
discussion. When the a Serializable class has an Abstract parent class 
that isn't serializable, that class needs to have a default no-arg 
constructor such that it can be instantiated. The solution to this is to 
maintain "implements Serializable" on the underlying Abstract parent, 
this is much simpler and more logical then writing default constructors 
for all the parent classes and it is considerably much easier to 
maintain. With this in mind we need to maintain implements Serializable 
on many our Abstract classes whose full implementations we want to 
maintain serialization on, I overlooked this on much of my previous 
Univariate work because those classes all use noarg constructors, when I 
removed serializable from the underlying Abstract classes, they were 
still functionaly serializable because they met this requirement. When 
working with the anaysis classes (which do not maintain no-arg 
constructors)  I encountered the correct serialization errors which 
should be expected when this requirement is not maintained.
