[Quantlib-dev] Serialisation change

[Plamen N. <pla...@re...>]

Hi all,

I'd like to commit a small change to the serialisation code in  
QuantLibAddin. It will remove the dependency of the serialised objects  
to the order in which the ValueObjects are registered in the code so  
that additions of new classes or removal of old ones will not break  
the compatibility of existing xml archives. How this works is very  
simple - a class id gets generated only when this class appears in the  
archive for the very first time. This ensures that id's are local to  
the archive and are only dependant on the classes serialised in this  
archive.

The down side is that this will break all existing exports - however  
those exports are anyway not very stable because chances are that they  
get broken with any new class being added in QLA.

Please let me know what you guys think...

cheers,
Plamen
