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.
log4tango::FileAppender::FileAppender(conststd::string&name,intfd)

Member Function Documentation
intlog4tango::FileAppender::_append(constLoggingEvent&event)[protected],[virtual]
Log in Appender specific way. Subclasses of Appender should implement this method to perform actual
logging.
Parametersevent The LoggingEvent to log.
Implements log4tango::Appender.
Reimplemented in log4tango::RollingFileAppender.
voidlog4tango::FileAppender::close(void)[virtual]
Closes the logfile.
Implements log4tango::Appender.
boollog4tango::FileAppender::get_append(void)const[virtual]
Gets the value of the 'append' option.
mode_tlog4tango::FileAppender::get_mode(void)const[virtual]
Gets the file open mode.
boollog4tango::FileAppender::is_valid(void)const[virtual]
Check if the appender is valid.
Returns
true if the appender is valid, false otherwise.
Reimplemented from log4tango::Appender.
boollog4tango::FileAppender::reopen(void)[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 log4tango::Appender.
voidlog4tango::FileAppender::set_append(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().
Parametersappend false to truncate, true to append
voidlog4tango::FileAppender::set_mode(mode_tmode)[virtual]
Sets the file open mode.
