Detailed Description

Logger factory.

This logging factory provides access to all loggers in a unified way. You just supply a logger argument string and depending on the logger type an instance of the desired logger is returned or otherwise an exception is thrown. See instance() for a list of supported logger types.

template<class L >

static L* fawkes::LoggerFactory::instance ( const char *  type, const char *  as  )

static

Get typed instance of logger.

Creates a new instance and converts it to the requested type. If the type does not match the requested logger an exception is thrown.

Parameters:

type	logger type
as	logger argument string

Returns:

typed logger instance

Exceptions:

TypeMismatchException

thrown, if requested logger does not match requested type.

MultiLogger * fawkes::LoggerFactory::multilogger_instance ( const char *  as )

static

Create MultiLogger instance.

This creates a multi logger instance based on the supplied argument string. The argument string is of the form

    ltype:largs[;ltype2:largs2[;...]]

So it is a list of logger type/argument tuples separated by columns concatenated to one list with exclamation marks. The list is not pre-processed, so if you mention a logger twice this logger is added twice.

Parameters:

as	logger argument string

Returns:

multi logger instance with requested loggers

Exceptions:

UnknownLoggerTypeException

thrown if any of the loggers was unknown.
