        Specified by:

      • doLayout

        public java.lang.String doLayout​(ILoggingEvent event)
        Deprecated.
        Description copied from interface: Layout
        Transform an event (of type Object) and return it as a String after appropriate formatting.

        Taking in an object and returning a String is the least sophisticated way of formatting events. However, it is remarkably CPU-effective.

        Parameters:
        event - The event to format
        Returns:
        the event formatted as a String
