Remarks

The call back is provided as an interface that needs to be implemented. The method onMessage() is called when a message that needs logging is available. Callback is only called for messages that have 'level' higher than or equal to the 'defaultThresholdLevel'. There can be only one callback that can be registered and if another callback is registered it will replace the previous one.

Usage example:
Copy
public class MyLogProcessor : Logging.Callback
{
    public void OnMessage(
        long threadId, TraceLevel level,
        Datetime dateTime, string loggerName, string message)
    {
        // Do some processing
    }
}
This callback needs to be registered with the library as:
Copy
var cb = new MyLogProcessor();
Logging.RegisterCallback(cb, TraceLevel.Warning);
