Is it possible to write a custom appender for log4cxx and have it configurable via a properties file (like the built-in appenders)? I'd prefer doing this without having to rebuild log4cxx (e.g. by deriving/extending an existing appender), if possible.
Can you point me toward an example?
Answer
You can inherit from AppenderSkeleton or WriterAppender and get the same underlying behaviors without having to rebuilt log4cxx.
