Member Function Documentation

void activateOptions log4cxx::helpers::Pool p  )  [virtual]
 

This method returns immediately as options are activated when they are set.

Reimplemented from AppenderSkeleton.

void append const spi::LoggingEventPtr event,
log4cxx::helpers::Pool p
[virtual]
 

Subclasses of AppenderSkeleton should implement this method to perform actual logging.

See also AppenderSkeleton::doAppend method.

Implements AppenderSkeleton.

void close  )  [virtual]
 

Release any resources held by this SyslogAppender.

Implements Appender.

LogString getFacility  )  const [inline]
 

Returns the value of the Facility option.

static int getFacility const LogString facilityName  )  [static]
 

Returns the integer value corresponding to the named syslog facility, or -1 if it couldn't be recognized.

Parameters:
facilityName one of the strings KERN, USER, MAIL, DAEMON, AUTH, SYSLOG, LPR, NEWS, UUCP, CRON, AUTHPRIV, FTP, LOCAL0, LOCAL1, LOCAL2, LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7. The matching is case-insensitive.

bool getFacilityPrinting  )  const [inline]
 

Returns the value of the FacilityPrinting option.

static LogString getFacilityString int  syslogFacility  )  [static]
 

Returns the specified syslog facility as a lower-case String, e.g.

"kern", "user", etc.

const LogString& getSyslogHost  )  const [inline]
 

Returns the value of the SyslogHost option.

void initSyslogFacilityStr  )  [protected]
 

virtual bool requiresLayout  )  const [inline, virtual]
 

The SyslogAppender requires a layout.

Hence, this method returns true.

Implements Appender.

void setFacility const LogString facilityName  ) 
 

Set the syslog facility.

This is the Facility option.

The facilityName parameter must be one of the strings KERN, USER, MAIL, DAEMON, AUTH, SYSLOG, LPR, NEWS, UUCP, CRON, AUTHPRIV, FTP, LOCAL0, LOCAL1, LOCAL2, LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7. Case is unimportant.

void setFacilityPrinting bool  facilityPrinting1  )  [inline]
 

If the FacilityPrinting option is set to true, the printed message will include the facility name of the application.

It is false by default.

void setOption const LogString option,
const LogString value
[virtual]
 

Set option to value.

The handling of each option depends on the OptionHandler instance. Some options may become active immediately whereas other may be activated only when activateOptions is called.

Reimplemented from AppenderSkeleton.

void setSyslogHost const LogString syslogHost  ) 
 

The SyslogHost option is the name of the the syslog host where log output should go.

WARNING If the SyslogHost is not set, then this appender will fail.
