Thank you to everyone for your quick assistance. Here is the code
snippet I did that worked:
Segment pidSegment = terser.getSegment("PID-5");
Type[] pid5Type = pidSegment.getField(5);
for (int indx = 0; indx < pid5Type.length; indx++) {
String subIndex = "(" + indx + ")";
terser.get("PID-5" + subIndx + "-1"); // gets familyName
terser.get("PID-5" + subIndx + "-2"); // gets givenName
}
A little ugly but it keeps things generic so you do not have to pick an
HL7 version number in the domain model.

Subject: How to access repeating fields using the generic Message type
Good afternoon,
I am trying to write a transformer which converts an HL7 message to a
local object graph. In doing so, I need to account for repeating
fields.
For example, PID-5 can have multiple names and we need to parse it out
into a List of PatientName objects (each PatientName object contains
family name, given name, and name type code).
Since we need to support many versions of HL7 we can not use a specific
v 2.x model data types. Instead we are relying on the generic:
ca.uhn.hl7v2.model.Message
ca.uhn.hl7v2.util.Terser
to parse the message.
I have had a difficult time finding simple examples of parsing repeating
fields using these generic classes.
I realize if we used
ca.uhn.hl7v2.model.v25.message
it would be easier to do this, but we need to remain version agnostic.
Can anyone assist me in a simple way to extract a repeating field as
mentioned above?
Thank you in advance,
Dan
