Re: [Quickfix-developers] How to add support for custom messages and custom signature to QuickFix?

[Oren M. <or...@qu...>]

If you want to generate all the classes, you will need to run the generation 
scripts in the 'spec' directory.

I don't believe there is a mehod for retrieving just the body fields.  In 
C++ this would be possible if you cast the Message to a FieldMap, but this 
isn't an option in java.  A getBody method would probably be a good 
compliment to getHeader and getTrailer.  What you can do however is iterate 
through all the fields and call toString on them one by one.  If you append 
each of the fields to a StringBuffer you should be able to reconstruct the 
body of the message.

Where you add the field is a function of what you know, when you know it, 
and how generally applicable it is.  In general, if you have a field that 
you want to make sure gets appended to every outgoing message, you should 
put it in the toApp method.  If you have a field that is specific to one 
type of message, it would make more sense to append it at the same place you 
construct that message.
