Re: [Boost-users] [serialization] transparently treating a class like abuilt-in type

I'm not sure I described things well enough. Say I have the following: typedef float Real; typedef Vector3<Real> Vector;

and I have some xml archives containing serialized Vector objects that look like this:

<x>-0.70032406</x> <y>-0.65001774</y> <z>0.29499683</z>

Now, I won't be able to read in this archive if I change the Real typedef like so:

typedef FixedPointClass Real;

Even if I make FixedPointClass serializable, the data would need to contain an additional name-value pair for it to be readable, like so:

<x><value>-0.70032406</value></x> <y><value>-0.65001774</value></y> <z><value>0.29499683</value></z>

Have you looked at the documentatoin regarding versioning? Does that not help? Robert Ramey
