concerning the ROOT extension with my own classes, I have a question.
In case I change the data part of a class, as explained in the tutorial
"Adding your own classes to ROOT", I must change the ClassVersionID in the
header file.
But then, if I recompile, can I still manage files written with the
previous version?
In other words, what happens if I try to read an old file with a library
compiled with the new header file?
Thanks in advance,
Piergiorgio
