I have a way, but I don't know if it is the best way. Castor defines
all its internal conversions in org.exolab.castor.jdo.engine.SQLTypes.
You can add your own to that class; just create two new TypeConvertor
objects (one for converting from a SQL int to your type of int, and one
for doing the reverse).
You also must _not_ specify the type of the java field in the mapping
file. If you do, it won't work. See
http://www.mail-archive.com/[email protected]/msg09981.html and bug
1093 ( http://bugzilla.exolab.org/show_bug.cgi?id=1093 ) for related
info.
So far as I know, there is no programmatic way to specify
TypeConvertors. Maybe there should be.
