Member Function Documentation

loggers::console_logger::DEFINE_CLASS_NAME ( "console_logger" )

outcome loggers::console_logger::log	(	const basis::base_string &	info,
		int	filter
	)			`[virtual]`

sends the string "info" to the standard output device.

if the "filter" is not in the current filter set, then the information will be dropped. otherwise the information is displayed, where appropriate. for some environments, this will essentially throw it away. for example, in ms-windows, a windowed program will only save standard out if one redirects standard output to a file, whereas a console mode program will output the text to its parent prompt.

Implements basis::base_logger.

Reimplemented in loggers::combo_logger.
