Re: [Quickfix-developers] Just Starting...

[azmat <mr...@gm...>]

Actually, I figured out the first part.  

fromApp, call crack...crack distinguishes what type of message it is and
calls the appropiate OnMessage that is overridden from MessageCracker...if
onMessage for the specific message type is NOT implemented, than an
UnsupportedMessageType  exception is thrown.  

So in the onMessage (execution report) I would write the business related
code for what I need to do for when/if an executionReport is a type of
message that is received, correct?  

My confusion now lies with sending messages with sendToTarget and its
relation to toApp?  Should I call sendToTarget from toApp or will it somehow
(again) magically end up in toApp?  

thanks!

Patrick,

Thanks! This is perfect.  I have something very similar now.  I understand
that I should call the crack method in the fromApp method so that the
MessageCracker can identify exactly what type of message it is.  That is
really neat.  But, what I do not get is how or when is the onMessage method
is called (the one that takes the ExecutionReport parameter)?  Is this
something that automagically happens with the crack method if it determines
the message is of type ExecutionReport?

Also on the flipside of it.  If I call sendToTarget from my business layer
will it automatically go to the Application.toApp method OR do I need to
somehow call toApp and then call sendToTarget from there?

Any help would be much, much appreciated!

thanks!
Azmat
