I’d prefer not to have to modify any source. I’d like to be able to add a custom segment just like you can add a custom message package. But, I’m not quite sure how to go about that. Any examples? I’m using the 0.42 build (no, I don’t want to update, it’s a LOT of re-coding.) If I need to modify source, I can, but as a last resort.
Thanks,
Tony

Thanks James,
I’ll give the addCustomSegment() a try.
At one point I moved from .3 to .42 and it was a pain.
>From your note, I’m guessing moving from .4 up shouldn’t be so much
work. I should give it a try. I’ve since done a conversion of
the 0.51 Java to C# and I’m working on converting all our code over.
Thanks for the help,

James,
I started to take a look at this and I think I wasn’t clear. I need to parse
messages with the non-standard segments, not create them. Can I just use the
Terser() functions to grab data? Will those non-standard segments be parsed?
Or will I need to add some parsing code somewhere?
Thanks again for the help,

Re: custom segments

Rate this Message:
Ah ok, I see what you mean. HAPI's PipeParser will happily parse messages with unexpected or custom segments and you will end up with a fully populated message, including the unexpected segments.
The major caveat is that the bahaviour can be a bit unexpected in that case. When PipeParser encounters a segment that isn't "supposed" to be there, it will recurse as deep as it can into the next segment group it encounters, and then start placing the segments there. I have found that depending on the structure of the message you are trying to parse and the location of the unexpected segment within the message, sometimes every segment after the unexpected one ends up attached to the wrong structure in the message. Oddly enough, this is behaviour that is fixed in the CVS version of PipeParser, and will be released with the next version.
If the custom segments you want to parse are at or near the end of the message, you shouldn't have any trouble. If they are closer to the front (and you don't want to upgrade) it's going to be possible, but a bit more work to find the data you are looking for.
Cheers,
James
