Dealing With Custom Layouts

Last updated 11 months ago

In order for an appender to deal with custom layouts, you must use the layout methods when preparing to log your messages. Below is a simple example from the console appender of how to do this:

if( hasCustomLayout() ){
entry = getCustomLayout().format(loge);
}
else{
entry = "#severityToString(loge.getseverity())# #loge.getCategory()# #loge.getmessage()# ExtraInfo: #loge.getextraInfoAsString()#";
}
‚Äč
// Log message to system.out
instance.out.println(entry);

As you can see, all you need to do is have an if statement that checks whether the appender has a custom layout or not and then assign the return of the layout as your message to log.
