bool folly::StreamHandlerFactory::WriterFactory::processOption ( StringPiece  name, StringPiece  value  )

inlineoverridevirtual

Process an option.

This should return true if the option was processed successfully, or false if this is an unknown option name. It should throw an exception if the option name is known but there is a problem with the value.
