Detailed Description

Class that logs messages into a file, optionally gzipped or otherwise compressed.

The file writing is provided in another thread to avoid the entire logger getting bogged down if a disk can't keep up.

Member Function Documentation

void Datacratic::NamedOutput::close ( ) [virtual]

Should close whatever resources are being used by the output and join any threads that it's created.

Definition at line 83 of file file_output.cc.

void Datacratic::NamedOutput::rotate	(	const std::string &	newFilename,
		const std::string &	newCompression = `""`,
		int	newLevel = `-1`
	)

Rotate the log file, finishing off writing the old one and then moving everything into the new one.

This is an asynchronous operation. It will return straight away.
