def queue
  raise Exception("AbstractMessage.queue() called - you need to override this in a subclass.")
end

#send(server) ⇒ Object

This causes the message to send itself over the server socket in server. “server” is the @server instance variable from the IB object. You can also use this to e.g. get the server version number.

Subclasses can either override this method for precise control over how stuff gets sent to the server, or else define a method queue() that returns an Array of elements that ought to be sent to the server by calling to_s on each one and postpending a ‘0’.
