Hi James,
First of all i would like to thank for pointing out the backward
compatibility feature. I will restructure my application based on that.
Also I will take a look at the Terser class and try to use it in my
application.
Thanks
Ram

Hi Ram,
You might have a look at the Terser class, which can help you populate
messages in a more generic way:
http://hl7api.sourceforge.net/xref/ca/uhn/hl7v2/examples/ExampleUseTerser.html
One thing to note is that the structures are backwards compatible
(this is a feature of the HL7 standard itself, not just of HAPI). Each
new version adds fields to the end of segments, adds segments to
messages, and deprecates certain parts of existing structures, but
does not fundamentally alter the structures. You could actually just
use a v25 structure to create a v23 message for example, so long as you:
1. Set the MSH-12 (Version) value to "2.3"
2. Use care not to populate fields/segments in the 2.5 structure that
are not used in the 2.3 equivalent.
Cheers,
James

Hi All,
I am developing an small application to generate the HL7 messages
using
HAPI. HAPI is very much helpful for me to develop the application.
But,
I do not have much exposure in all the HAPI classes.
I can able to generate the HL7 messages successfully. But i did
not use
generic approach for all the versions of HL7 message.
Currently I am using different methods for each version. For example,
createV231MSHSegement(ca.uhn.hl7v2.model.v231.segment.MSH);
createV251MSHSegement(ca.uhn.hl7v2.model.v251.segment.MSH);
Is there any class in the HAPI to make this generic single method? Can
anyone suggest me the better solution to my issue.
Thanks
Ram
