class EventMachine::FileStreamer

Streams a file over a given connection. Streaming begins once the object is instantiated. Typically FileStreamer instances are not reused.

Streaming uses buffering for files larger than 16K and uses so-called fast file reader (a C++ extension) if available (it is part of eventmachine gem itself).

@example

module FileSender
  def post_init
    streamer = EventMachine::FileStreamer.new(self, '/tmp/bigfile.tar')
    streamer.callback{
      # file was sent successfully
      close_connection_after_writing
    }
  end
end
