Re: [Quickfix-developers] Application Class Methods - Begginer

[Dale W. <wi...@oc...>]

Hi Joaquin,
It is important to understand that FIX is a bidirectional asynchronous 
protocol.   Messages are flowing in both directions.  An incoming 
message can arrive at any time.  The methods you talk about [with the 
exception of onCreate]  are the ones that QuickFIX uses to report to the 
application that some action has taken place based on an incoming. message.

For methods going the other direction, you want to call methods on the 
Session object.  I think you'll find what you are looking for (logon, 
logout, send, etc) there.
