Jean-Pierre,
I was also thinking that it would be very useful for all classes to provide
generic forms of the Get/Set Data methods. These would have a variant data
input/output and also take a U32 reference input/output. This would enable
the creation of many kinds of useful utilities to operate on OpenGOOP
classes. For example, I am interested in an data inspector/editor. The
utility that you mentioned would also be very useful.
