Subject AW: how to map Peer.field-name --> BO-member
Date Tue, 14 Jan 2003 13:40:53 GMT
Thanks, that's good to know.
But I think this would be a useful function.
My first idea was simply de-capitalize the FIELD obtained from the Peer and
then use introspection to get the corresponding field or get-method from the
BO.
But as you mentioned, the database column name and the BO-member name might
not correspond directly.
So I'm afraid this demands a solution on a more lower level. Best would be
if torque adds additional methods at the time of BO creation.

Actually, perhaps just adding generic functionality to
BaseObject.getByName(java.lang.String field) would do the job.
