`std::string`	`dir` `const` `inline`	Returns the directory where log files are written.
`std::string`	`filename` `const` `inline`	Returns the filename of the currently open log file.
`int`	`rotationInterval` `const` `inline`	Returns the rotation interval in seconds.
`void`	`setDir` `inline`	Sets the output directory for rotated log files.
`void`	`setExtension` `inline`	Sets the file extension for rotated log files.
`void`	`setRotationInterval` `inline`	Sets the rotation interval.

RotatingFileChannel

RotatingFileChannel(std::string name, std::string dir, Level level, std::string extension, int rotationInterval, std::string timeFormat)

Parameters

name Unique channel name.
dir Directory in which rotated log files are written.
level Minimum severity level; messages below this level are dropped.
extension File extension for log files (without leading dot).
rotationInterval Seconds between log rotations (default: 12 hours).
timeFormat strftime-compatible format string for timestamps.

write

virtual

virtual void write(const LogStream & stream)

Formats and writes the log stream entry to the current log file. Rotates the file if the rotation interval has elapsed.

Parameters

stream The log stream to write.

rotate

virtual

virtual void rotate()

Closes the current log file and opens a new one with a timestamped filename.

dir

const inline

inline std::string dir() const

Returns the directory where log files are written.

filename

const inline

inline std::string filename() const

Returns the filename of the currently open log file.

rotationInterval

const inline

inline int rotationInterval() const

Returns the rotation interval in seconds.

setDir

inline

inline void setDir(std::string dir)

Sets the output directory for rotated log files.

Parameters

dir Target directory path.

setExtension

inline

inline void setExtension(std::string ext)

Sets the file extension for rotated log files.

Parameters

ext Extension without leading dot (e.g. "log").

setRotationInterval

inline

inline void setRotationInterval(int interval)

Sets the rotation interval.

Parameters

interval Number of seconds between rotations.
