Detailed Description

This is a singleton class.

The logger pointer is obtained when needed by calls to getTheLog(), only the first of which actually creates the object and initializes the output.

Member Enumeration Documentation

LogLevel

enum Logger::LogLevel

Log level values.

Messages at level above the current will not be printed. Messages at a level above LOGGER_STATICVERBOSITY will not even be compiled in.

Member Function Documentation

getstream()

std::ostream& Logger::getstream ( )

inline

Retrieve the output stream in case you need to write directly to it.

In a multithreaded program, you probably also need to obtain the mutex with getmutex, and lock it.

getTheLog()

Logger * Logger::getTheLog ( const std::string &  fn = std::string() )

static

Initialize logging to file name.

Use "stderr" for stderr output. Creates the singleton logger object. Only the first call changes the state, further ones just return the Logger pointer.

reopen()

bool Logger::reopen

(

const std::string &

fn

)

Close and reopen the output file.

For rotating the log: rename then reopen.

setdateformat()

void Logger::setdateformat ( const std::string  fmt )

inline

Set the date format, as an strftime() format string.

Default: "%Y%m%d-%H%M%S" .
