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.

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.

LogString getFacility ( ) const

inline

Returns the value of the Facility option.

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

inlinevirtual

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.
