RE: [HAPI-devel] Thoughts for sourcegen, offer to help

Hi Mike, 

Thanks, this does seem like a good way to handle new fields that are
introduced at the end of a segment.  I don't think it would work so well
when components are added to a field, or segments to a group.  For example
if a field changes from ID to CE, you would need accessors for both, which
wouldn't be too much better than what we have now.  

I want to make sure you're aware of ca.uhn.hl7v2.util.Terser.  It provides a
string syntax for accessing primitives in a version-independent manner --
maybe this is what you mentioned for primitives in the current CVS code.
You retrieve data with address strings like "MSH-9-3" and it will account
for version-related differences.  This is how the core HAPI classes deal
with this problem.  

If Terser doesn't meet your needs and you don't mind the above limitations,
then you're more than welcome to give it a shot and I'll try to be of
assistance.

Worse ... it's sold separately (for $1200 USD!)
