Member Function Documentation

◆ activateOptions()

virtual void log4cxx::AppenderSkeleton::activateOptions ( log4cxx::helpers::Pool & )

inlinevirtual

Derived appenders should override this method if option structure requires it.

Implements log4cxx::spi::OptionHandler.

Reimplemented in log4cxx::DailyRollingFileAppender, log4cxx::db::ODBCAppender, log4cxx::FileAppender, log4cxx::net::SocketHubAppender, log4cxx::net::SMTPAppender, log4cxx::net::TelnetAppender, log4cxx::RollingFileAppender, log4cxx::WriterAppender, log4cxx::net::SyslogAppender, log4cxx::net::SocketAppenderSkeleton, log4cxx::rolling::RollingFileAppenderSkeleton, log4cxx::ConsoleAppender, and log4cxx::nt::NTEventLogAppender.

◆ addFilter()

void log4cxx::AppenderSkeleton::addFilter ( const spi::FilterPtr & newFilter )

virtual

Add a filter to end of the filter list.

Implements log4cxx::Appender.

◆ append()

virtual void log4cxx::AppenderSkeleton::append	(	const spi::LoggingEventPtr &	event,
		log4cxx::helpers::Pool &	p
	)

protectedpure virtual

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

See also AppenderSkeleton::doAppend method.

Implemented in log4cxx::db::ODBCAppender, log4cxx::net::SocketHubAppender, log4cxx::net::TelnetAppender, log4cxx::net::XMLSocketAppender, log4cxx::WriterAppender, log4cxx::net::SocketAppender, log4cxx::net::SMTPAppender, log4cxx::nt::NTEventLogAppender, log4cxx::AsyncAppender, log4cxx::net::SyslogAppender, and log4cxx::nt::OutputDebugStringAppender.

◆ clearFilters()

void log4cxx::AppenderSkeleton::clearFilters ( )

virtual

Clear the filters chain.

Implements log4cxx::Appender.

◆ doAppend()

virtual void log4cxx::AppenderSkeleton::doAppend	(	const spi::LoggingEventPtr &	event,
		log4cxx::helpers::Pool &	pool
	)

virtual

This method performs threshold checks and invokes filters before delegating actual logging to the subclasses specific AppenderSkeleton::append method.

Implements log4cxx::Appender.

Reimplemented in log4cxx::AsyncAppender.

◆ doAppendImpl()

void log4cxx::AppenderSkeleton::doAppendImpl	(	const spi::LoggingEventPtr &	event,
		log4cxx::helpers::Pool &	pool
	)

protected

◆ finalize()

void log4cxx::AppenderSkeleton::finalize ( )

Finalize this appender by calling the derived class' close method.

◆ getErrorHandler()

const spi::ErrorHandlerPtr& log4cxx::AppenderSkeleton::getErrorHandler ( ) const

inline

Return the currently set spi::ErrorHandler for this Appender.

◆ getFilter()

spi::FilterPtr log4cxx::AppenderSkeleton::getFilter ( ) const

inlinevirtual

Returns the head Filter.

Implements log4cxx::Appender.

◆ getFirstFilter()

const spi::FilterPtr& log4cxx::AppenderSkeleton::getFirstFilter ( ) const

inline

Return the first filter in the filter chain for this Appender.

The return value may be 0 if no is filter is set.

◆ getLayout()

LayoutPtr log4cxx::AppenderSkeleton::getLayout ( ) const

inlinevirtual

Returns the layout of this appender.

The value may be 0.

Implements log4cxx::Appender.

◆ getName()

LogString log4cxx::AppenderSkeleton::getName ( ) const

inlinevirtual

Returns the name of this Appender.

Implements log4cxx::Appender.

◆ getThreshold()

const LevelPtr& log4cxx::AppenderSkeleton::getThreshold ( ) const

inline

Returns this appenders threshold level.

See the setThreshold method for the meaning of this option.

◆ isAsSevereAsThreshold()

bool log4cxx::AppenderSkeleton::isAsSevereAsThreshold ( const LevelPtr & level ) const

Check whether the message level is below the appender's threshold.

If there is no threshold set, then the return value is always true.

◆ setErrorHandler()

void log4cxx::AppenderSkeleton::setErrorHandler ( const spi::ErrorHandlerPtr eh )

Set the ErrorHandler for this Appender.

◆ setLayout()

void log4cxx::AppenderSkeleton::setLayout ( const LayoutPtr & layout1 )

inlinevirtual

Set the layout for this appender.

Note that some appenders have their own (fixed) layouts or do not use one. For example, the SocketAppender ignores the layout set here.

Implements log4cxx::Appender.

◆ setName()

void log4cxx::AppenderSkeleton::setName ( const LogString & name1 )

inlinevirtual

Set the name of this Appender.

Implements log4cxx::Appender.

◆ setOption()

virtual void log4cxx::AppenderSkeleton::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.

Implements log4cxx::spi::OptionHandler.

Reimplemented in log4cxx::DailyRollingFileAppender, log4cxx::AsyncAppender, log4cxx::WriterAppender, log4cxx::net::SocketAppenderSkeleton, log4cxx::db::ODBCAppender, log4cxx::FileAppender, log4cxx::net::SocketHubAppender, log4cxx::net::TelnetAppender, log4cxx::RollingFileAppender, log4cxx::net::SMTPAppender, log4cxx::net::SyslogAppender, log4cxx::ConsoleAppender, and log4cxx::nt::NTEventLogAppender.

◆ setThreshold()

void log4cxx::AppenderSkeleton::setThreshold ( const LevelPtr & threshold )

Set the threshold level.

All log events with lower level than the threshold level are ignored by the appender.

In configuration files this option is specified by setting the value of the Threshold option to a level string, such as "DEBUG", "INFO" and so on.
