Constructor & Destructor Documentation

log4cpp::FileAppender::FileAppender	(	const std::string &	name,
		const std::string &	fileName,
		bool	append = `true`,
		mode_t	mode = `00644`
	)

Constructs a FileAppender.

Parameters:

	name	the name of the Appender.
	fileName	the name of the file to which the Appender has to log.
	append	whether the Appender has to truncate the file or just append to it if it already exists. Defaults to 'true'.
	mode	file mode to open the logfile with. Defaults to 00644.

Definition at line 27 of file FileAppender.cpp.

log4cpp::FileAppender::FileAppender	(	const std::string &	name,
		int	fd
	)

Constructs a FileAppender to an already open file descriptor.

Parameters:

	name	the name of the Appender.
	fd	the file descriptor to which the Appender has to log.

Member Function Documentation

void log4cpp::FileAppender::_append ( const LoggingEvent & event ) [protected, virtual]

Log in Appender specific way. Subclasses of Appender should implement this method to perform actual logging.

Parameters:

event

The LoggingEvent to log.

Implements log4cpp::AppenderSkeleton.

Reimplemented in log4cpp::RollingFileAppender.

Definition at line 87 of file FileAppender.cpp.

void log4cpp::FileAppender::close ( ) [virtual]

Closes the logfile.

Implements log4cpp::AppenderSkeleton.

Definition at line 60 of file FileAppender.cpp.

bool log4cpp::FileAppender::getAppend ( ) const [virtual]

Gets the value of the 'append' option.

Definition at line 75 of file FileAppender.cpp.

mode_t log4cpp::FileAppender::getMode ( ) const [virtual]

Gets the file open mode.

Definition at line 83 of file FileAppender.cpp.

bool log4cpp::FileAppender::reopen ( ) [virtual]

Reopens the logfile. This can be useful for logfiles that are rotated externally, e.g. by logrotate. This method is a NOOP for FileAppenders that have been constructed with a file descriptor.

Returns:: true if the reopen succeeded.

Reimplemented from log4cpp::AppenderSkeleton.

Definition at line 94 of file FileAppender.cpp.

void log4cpp::FileAppender::setAppend ( bool append ) [virtual]

Sets the append vs truncate flag. NB. currently the FileAppender opens the logfile in the constructor. Therefore this method is too late to influence the first file opening. We'll need something similar to log4j's activateOptions().

Parameters:

append

false to truncate, true to append

Definition at line 67 of file FileAppender.cpp.

void log4cpp::FileAppender::setMode ( mode_t mode ) [virtual]

Sets the file open mode.

Definition at line 79 of file FileAppender.cpp.
