Subject: Re: [HAPI-devel] Escaping Encoded characters
In HL7 v2.5 the MSH-9 segment is a datatype with 3 fields. HAPI supports this,
so it gives you getters and setters for all the components in the datatype.
To set up what you want you can do the following:
mshSegment.getMsh9_MessageType().getMessageCode().getMsg1_MessageCode().setValue("ORR");
mshSegment.getMsh9_MessageType().getMessageCode().getMsg2_TriggerEvent().setValue("O02");
HAPI also knows all about escaping, and does it's level best to make your life
easy.
If you want to get data escaped in a field, just use the setValue method with
your string in java.
So to build an ACK with the MSA-3 containing escaped ~ characters you can do
the following:
ACK myAck = new ACK();
myAck.initQuickstart("ACK", "", "P");
myAck.getMSA().getMsa1_AcknowledgmentCode().setValue("PD");
myAck.getMSA().getMsa2_MessageControlID().setValue("879-0999-1");
myAck.getMSA().getMsa3_TextMessage().setValue("Text1~Text2~Text3");
System.out.println(myAck.getMSA().encode());
The output of which is:
MSA|PD|879-0999-1|Text1\R\Text2\R\Text3
Which is what you have asked for. HAPI does the escaping when you encode your
result ready for sending.
When you receive a message with escaped delimiter characters and parse it with
HAPI, a getValue method will un-escape the characters for you, and give you a
java string result.
HAPI really knows HL7, and does a lot to help you. We have had a lot of success
using it for many years now.
Hope this helps

Subject: [HAPI-devel] Escaping Encoded characters
I want to be able to escaped the special encoding characters by using \S\ or
\R\ but this doesn't seem to work for me.
I also tried the code snippet below but it seems that using the quick start
init method creates multiple repetitions of the message type, for example:
ORR_O02 orr002=new ORR_O02();
MSH mshSegment = orr002.getMSH();
orr002.initQuickstart("ORR", "002", "P"); results in the message below
with the message type repeated which is not what I want:
MSH|^~\&|CDB||MCK||20010925202704||ORR^002^ORR_O02|1301|P|2.5
Instead I only want
MSH|^~\&|CDB||MCK||20010925202704||ORR^002 |1301|P|2.5
I tried setting the message code like so:
mshSegment.getMsh9_MessageType().getMessageCode().setValue("ORR\\S\\002"); but
this produces
MSH - MSH|^~\&|CDB||MCK||20010925202704||ORR\E\S\E\002|||2.5
It's not clear how to accomplish escaping encoding characters. How does one do
that, since the above does not work?
For example, I want to escaped the tilde in the message below, can this be
done and how? I hoped \R\ would work but it didn't.
MSA|PD|879-0999-1|Text1~Text2~Text3
