Macro Definition Documentation

#define madara_logger_cond_log	(		conditional,
			logger,
			alt_logger_ptr,
			level,
			...
	)

Value:

if (conditional && level <= logger.get_level ()) \
            logger.log (level, __VA_ARGS__); \
                    else \
            alt_logger_ptr->log (level, __VA_ARGS__);

High-performance logger that performs conditional logging based on first arg.

Parameters

conditional	the primary logger pointer to use (if not null)
logger	the logger that will be used if conditional is true
alt_logger_ptr	the secondary logger pointer to use (should be not null)
level	the logging level

#define madara_logger_cond_log_ptrs	(		conditional,
			logger_ptr,
			alt_logger_ptr,
			level,
			...
	)

Value:

if (conditional && logger_ptr && level <= logger_ptr->get_level ()) \
            logger_ptr->log (level, __VA_ARGS__); \
          else \
            alt_logger_ptr->log (level, __VA_ARGS__);

High-performance logger that performs conditional logging based on first arg.

Parameters

conditional	the primary logger pointer to use (if not null)
logger_ptr	the logger that will be used if conditional is true
alt_logger_ptr	the secondary logger pointer to use (should be not null)
level	the logging level

#define madara_logger_log	(		logger,
			level,
			...
	)

Value:

if (level <= logger.get_level ()) \
            logger.log (level, __VA_ARGS__);

Fast version of the madara::logger::log method.

This macro uses compiler optimizations to ensure that args are not evaluated unless the level is appropriate for the loggers level. This makes logging transparent and minimally invasive, performance wise

Parameters

logger	the logger instance to use
level	the logging level

Definition at line 20 of file Logger.h.

#define madara_logger_ptr_log	(		logger,
			level,
			...
	)

Value:

if (logger && level <= logger->get_level ()) \
            logger->log (level, __VA_ARGS__);

Fast version of the madara::logger::log method for Logger pointers.

This macro uses compiler optimizations to ensure that args are not evaluated unless the level is appropriate for the loggers level. This makes logging transparent and minimally invasive, performance wise

Parameters

logger	the logger pointer to use
level	the logging level
