Class NOPLogger

    • Constructor Detail

      • NOPLogger

        protected NOPLogger()
        There is no point in creating multiple instances of NOPLogger, except by derived classes, hence the protected access for the constructor.

      • readResolve

        protected Object readResolve()
                              throws ObjectStreamException
        Replace this instance with a homonymous (same name) logger returned by LoggerFactory. Note that this method is only called during deserialization.

        This approach will work well if the desired ILoggerFactory is the one references by LoggerFactory. However, if the user manages its logger hierarchy through a different (non-static) mechanism, e.g. dependency injection, then this approach would be mostly counterproductive.

        Returns:
        logger with same name as returned by LoggerFactory
        Throws:
        ObjectStreamException
