Hi Ryan,
You're right ...
I have already extended the Terser class with methods to determine if
a field/component is empty or null.
As soon as it's complete I can send it to you.
Best Regards
Nico

I am trying to understand how you traverse through a random message
in a terser. I guess I would look in the MSH to determine what
Message type it is. But after that how do I actually iterate the
message. How do you tell how many repetitions are present of a
group or field? How do you tell if an optional group is present or not?
The only way I can think is just by testing for it and catching
exceptions, but that is pretty ugly. Essentially I am looking for a
method like:
public boolean isPresent(String spec)
Does something like that exist?
thanks
