std::vector< LevelAndEvent > LogEventList
Convenience typedef for a vector of LevelAndEvent instances.
boost::shared_ptr< log4cplus::spi::InternalLoggingEvent > LogEventPtr
Convenience typedef for a pointer to a log event.
virtual const char * what() const
Returns a C-style character string of the cause of the exception.
virtual void close()
Close the appender.
LogBufferAddAfterFlush(const char *file, size_t line, const char *what)
std::pair< std::string, LogEventPtr > LevelAndEvent
Convenience typedef for a pair string/logeventptr, the string representing the logger level...
This is a base class for exceptions thrown from the DNS library module.
Defines the logger used by the top-level component of kea-lfc.
