Constructor & Destructor Documentation

log4cpp::FileAppender::FileAppender (const std::string &name, const std::string &fileName, boolappend = true, mode_tmode = 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.

log4cpp::FileAppender::FileAppender (const std::string &name, intfd)

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.

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

Closes the logfile.

Implements log4cpp::AppenderSkeleton.

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

Gets the value of the 'append' option.

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

Gets the file open mode.

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.

void log4cpp::FileAppender::setAppend (boolappend) [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

void log4cpp::FileAppender::setMode (mode_tmode) [virtual]

Sets the file open mode.
