Constructs a FileAppender to an already open file descriptor. | |
virtual | ~FileAppender () |
Destructor. | |
virtual bool | reopen (void) |
Reopens the logfile. | |

Closes the logfile. | |

Check if the appender is valid. | |

const std::string & | fileName, | ||
bool | append = true , |
||
mode_t | mode = 00644 |
||
) |
Constructs a FileAppender.
log4tango::FileAppender::FileAppender | ( | const std::string & | name, |
int | fd | ||
) |
Constructs a FileAppender to an already open file descriptor.
log4tango::FileAppender::~FileAppender | ( | ) | [virtual] |
Destructor.
int log4tango::FileAppender::_append | ( | const LoggingEvent & | event | ) | [protected, virtual] |
Log in Appender specific way.
Subclasses of Appender should implement this method to perform actual logging.
event | The LoggingEvent to log. |
Implements log4tango::Appender.
Reimplemented in log4tango::RollingFileAppender.
void log4tango::FileAppender::close | ( | void | ) | [virtual] |
Closes the logfile.
Implements log4tango::Appender.
bool log4tango::FileAppender::get_append | ( | void | ) | const [virtual] |
Gets the value of the 'append' option.
mode_t log4tango::FileAppender::get_mode | ( | void | ) | const [virtual] |
Gets the file open mode.
bool log4tango::FileAppender::is_valid | ( | void | ) | const [virtual] |
Check if the appender is valid.
Reimplemented from log4tango::Appender.
bool log4tango::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.
Reimplemented from log4tango::Appender.
void log4tango::FileAppender::set_append | ( | 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().
append | false to truncate, true to append |
void log4tango::FileAppender::set_mode | ( | mode_t | mode | ) | [virtual] |
Sets the file open mode.
