RE: [HAPI-devel] Problems with PipeParser

[Tripp, B. <Bry...@uh...>]

For the list, the explanation is as follows ... 
 
This code prints the message to the console after each segment is added.
There are no line feeds at the ends of HL7 segments, and Bill was using the
XP console, so the results of each println statement go on a single line,
with each segment overwriting the last.  So the first line is the MSH, the
second line is the MSH with the PID overwriting part of it, and the third is
the MSH overwritten by the PID overwritten by the OBR.  Everything looks
sensible when the output is written somewhere that sees \r as a line break
(e.g. the Eclipse console or a file).

Subject: [HAPI-devel] Problems with PipeParser



Hi all, 
I'm having newbie problems getting PipeParser to behave the way I think it
should.  If I build up a basic ORU_R01 message (code that does the work is
down below), and ask PipeParser to write it out, I get the following output.
Note that all the lines are the same length - it seems like it's not
flushing a string buffer between segments.  The same message works fine
written out through the XML parser (which, unfortunately, doesn't help me
much). Any ideas? Am I doing something wrong here?? 
Thanks all 
-Bill Hansley 

PS - Thanks, Bryan, for coordinating such a great and useful
product/project!!
