Re: [Quickfixj-users] repeating group problem

[<st...@te...>]

Hi Alvin,

I understand and I tend to agree. However, I'd like to hear Oren's
comments on these issues. The core QFJ API is based on the QF API
and it's our goal to keep them compatible when moving from QF to QFJ.

That said, one of the features being planned for a post 1.1.0
release is to completely decouple the session protocol engine
from the generated message/field code. This will give increased
flexibility for packaging and using custom message representations
although they must still be based on quickfix.Message. For example,
we intend to provide a message representation that uses BigDecimal
for prices and other values that need precise representations.

My long term vision is to redesign the parsing engine to allow
mapping of FIX messages directly to POJOs that aren't required to
inherit from quickfix.Message at all. I'm not sure when I'll have
time to do that since QFJ is a spare time project for me. ;-)
