Detailed Description

Logs proxy streams to files.

Date

2003

Construct a logger and subscribe it to proxy streams so it can log them. All output to all proxy streams it is subscribed to will be saved to a file. Per proxy stream you can set a filter of what messages should be logged. The logger will unsubscribe itself on destruction.

Logger logger("logfile.txt");       // construct logger\n
logger.subscribe(proxyOut());       // subsribe to the proxy out stream.\n
...\n
logger.unsubscribe(proxyOut());\n

Constructor & Destructor Documentation

Logger()

lass::io::Logger::Logger	(	const std::string &	iLogFilename,
		LogMode	iLogMode = lmClear )

Default constructor for the sake of static library.

We don't recommend of using it. Create a logger to a log file and specify if it must append to the file or clear it.
