Re: [Quickfix-developers] How to suppress 35=X messages in log file

[Gunnar H. <gh...@hi...>]

Thanks Mike!

I create an acceptor with a FIX::FileLogFactory because I do want the logging to file of all messages except the 35=X. I have stream and trade sessions. For the trade session i want all logging and for stream session all but the 35=X. So I think I use the appropriate constructor of the acceptor.

Deriving from the FileLogFactory and from FileLog to create my own derived FileLog is probably easy but in the onOutgoing method of the Log object the message type is not available, only the message string and I don't want to search in the message string for 35=X because that is a waste of time and totally not nice.

Regards,
Gunnar

But then I must search in the message string for subsstrings like 35=X which is a waste of time since in FIX::Session send methods is available the MsgType.
