RE: GOOP and INI files

[Jim K. <jim...@ja...>]

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.

-Jim
