Detailed Description

A Logger base class. The base types, and string objects can be passed to the Logger as messages. Messages are only passed to the logger, iff the minLevel is not higher than level, and minLevel is different from L_NONE. Otherwise the messages are simply ignored. Passing a message <message> to the Logger <logger> at LogLevel <loglevel> would look like <logger> << Level(<loglevel>) << <message>;

Member Function Documentation

static EXL void sx::Logger::addLogger	(	string	ID,
		Logger *	logger
	)

static

Adds a logger with identifyer ID to the loggers map. If another logger with the same ID exists already, or the pointer logger has value 0, an exception is thrown.

Parameters

ID	unique identifyer of the logger
logger	a new logger, must not be 0

Exceptions

an	exception of type Exception is thrown, if another logger has identifyer ID

static EXL void sx::Logger::deleteLogger ( string ID )

static

Deletes the logger with identifyer ID. If no logger with identifyer ID exists, an exception is thrown.

Parameters

ID	identifyer of logger, which should be deleted

Exceptions

exception of type Exception is thrown, if an error occurs

static EXL Logger& sx::Logger::get ( )

static

Returns the default logger. A valid default logger must always exist.

Returns: reference of the default logger

EXL LogLevel sx::Logger::getLevel ( ) const

getter

EXL LogLevel sx::Logger::getMinLevel ( ) const

getter

static EXL string sx::Logger::newLine ( )

static

returns newline

virtual EXL Logger& sx::Logger::operator<< ( const Level l )

virtual

Changes the minLevel of the logger to l. The following messages are ignored, if l is L_NONE or greater than level.

Parameters

l	new level of the logger

Returns: a reference to this object

Reimplemented in sx::FileLogger, sx::ListLogger, and sx::ConsoleLogger.

virtual EXL Logger& sx::Logger::operator<< ( const LogMarkup m )

pure virtual

Appends a new LogMarkup to the Logger. Each new Message passed to the logger is part of the new markup. Markups are passed to the log independently from the values of level and minLevel.

Parameters

m	new LogMarkup

Returns: a reference to this object

Implemented in sx::FileLogger, sx::ListLogger, and sx::ConsoleLogger.

virtual EXL Logger& sx::Logger::operator<< ( const Annotation a )

pure virtual

Appends a new Annotation to the Logger. Annotation should be used to document the messages passed to the logger. Annotations are passed to the log independently from the values of level and minLevel.

Parameters

a	Annotation

Returns: a reference to this object

Implemented in sx::FileLogger, sx::ListLogger, and sx::ConsoleLogger.

virtual EXL Logger& sx::Logger::operator<< ( char value )

pure virtual
