This function is for derived appenders to call from their destructors. bool isClosed () const
Check if this appender is in closed state. void syncDoAppend (const log4cplus::spi::InternalLoggingEvent &event)

Get the filter chain on this Appender. void addFilter (log4cplus::spi::FilterPtr f)
Add filter at the end of the filters chain. void addFilter (std::function< spi::FilterResult(const log4cplus::spi::InternalLoggingEvent &)>)
Add filter at the end of the filters chain. LogLevel getThreshold () const
Returns this appenders threshold LogLevel. void setThreshold (LogLevel th)
Set the threshold LogLevel. bool isAsSevereAsThreshold (LogLevel ll) const
Check whether the message LogLevel is below the appender's threshold. void waitToFinishAsyncLogging ()
