Classes
class	nidas::util::LoggerPrivate

Namespaces
	nidas
	Root namespace for the NCAR In-Situ Data Acquisition Software.
	nidas::util
	General utility classes. nidas::util contains classes of general utility, like Socket, Thread, etc. The classes use only the standard Unix system libraries and libstdc++, and have no dependency on other external packages such as an XML parser, or a logging package.

Macros

Typedefs
typedef vector< LogContext * >	log_points_v
typedef map< string, LogScheme >	log_schemes_t

Functions
static LogScheme	get_scheme (const std::string &name)
	Get a scheme with the name, or return a default. More...
static LogScheme *	lookup_scheme (const std::string &name)
	This must be called while the mutex is locked, since it accesses the shared LogScheme map, and it returns a pointer which might change once the lock is released. More...
static void	stream_backtrace (std::ostream &out)
static string	fillError (string fmt)
bool	parse_log_level (int &level_out, const std::string &text)
int	nidas::util::stringToLogLevel (const std::string &slevel)
	Convert the name of a log level to its integer value. More...
string	nidas::util::logLevelToString (int)
	Convert an integral log level to a string name. More...

Variables
static log_points_v	log_points
	Vector of pointers to all the LogContext instances initialized so far. More...
static log_schemes_t	log_schemes
	Map of all the known LogScheme instances. More...
static LogScheme	current_scheme = get_scheme("")
static LogScheme::LogField	default_fields []
