Implementation base class for all appenders.

This class provides the code for common functionality, such as support for threshold filtering and support for general filters.

clearFilters()

void log4cxx::AppenderSkeleton::clearFilters ( ) overridevirtual

doAppend()

doAppendImpl()

finalize()

void log4cxx::AppenderSkeleton::finalize ( )

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

getErrorHandler()

getFilter()

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

getFirstFilter()

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

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

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

getLayout()

LayoutPtr log4cxx::AppenderSkeleton::getLayout ( ) const overridevirtual

Returns the layout of this appender.

The value may be nullptr.

Implements log4cxx::Appender.

getName()

LogString log4cxx::AppenderSkeleton::getName ( ) const overridevirtual

getThreshold()

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

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()

setLayout()

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

Set the layout for this appender.

Note that some appenders have their own (fixed) layouts or do not use one.

Implements log4cxx::Appender.

setName()

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

setOption()

void log4cxx::AppenderSkeleton::setOption ( const LogString & option, const LogString & value ) overridevirtual

Implements log4cxx::spi::OptionHandler.

Reimplemented in log4cxx::AsyncAppender, log4cxx::ConsoleAppender, log4cxx::db::DBAppender, log4cxx::db::ODBCAppender, log4cxx::FileAppender, log4cxx:🥅:SMTPAppender, log4cxx:🥅:SocketAppenderSkeleton, log4cxx:🥅:SyslogAppender, log4cxx:🥅:TelnetAppender, log4cxx::nt::NTEventLogAppender, log4cxx::rolling::RollingFileAppender, and log4cxx::WriterAppender.

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.
