Description

This will be probably used by all the async libraries like EventMachine. It expects the whole frame as one string, so if library of your choice gives you input chunk-by-chunk, you'll need to have something like this:

class Client

include EventMachine::Deferrable

def receive_data(chunk)
  if @payload.nil?
    self.decode_from_string(chunk[0..6])
    @payload = ""
  elsif @payload && chunk[-1] != FINAL_OCTET
    @payload += chunk
    @size += chunk.bytesize
  else
    check_size(@size, @payload.bytesize)
    Frame.decode(@payload) # we need the whole payload
    @size, @payload = nil
  end
end

NOTE: the client should also implement waiting for another frames, in case that some header/body frames are expected.

end
