Member Function Documentation

void orcalog::LogWriter::createLogFile	(	const std::string &	filename,
		const std::string &	format
	)			[protected, virtual]

This version correctly handles two standard log file formats: ice : binary file ascii : ascii file This function does not catch exceptions which may result when creating a file. Derived classes which want to modify this behavior or need to handle other formats need to re-implement this function.

References file_, orcalog::openAsciiFileForWriting(), and orcalog::openBinaryFileForWriting().

Referenced by init().

void orcalog::LogWriter::writeReferenceToMasterFile

(

const orca::Time &

arrivalTime

)

[inline, protected]

Appends a record to the master file. Supplies the LogWriter ID and the data counter. Also prints out heartbeat message periodically.
