Ruby Method for Casting

I am new to ruby development and I am making a simple chat server encrypted over TLS.

I have managed to get the basic server running however I now want to add special properties to each of the connected clients (username, etc.)

I have this class which I plan to use for each client that connects:

class Client < OpenSSL::SSL::SSLSocket
    attr_accessor :username
    ...
end

I need to get a Client object from the OpenSSL::SSL::SSLServer.accept function in order to set the username attribute. I am used to C type languages where casting would do the trick but Google has told me that this is not the case in Ruby.

What is the Ruby way of doing this?

There are essentially 2 ways to solve your problem:

  1. delegation: create Client as a wrapper with an instance variable of class OpenSSL::SSL::SSLSocket. Client would then have to understand and forward messages to SSLSocket. Could get complicated.
  2. extension: use class_eval to add instance variables and/or methods directly to SSLSocket. This is a commonly-used Ruby approach.

You don't need casting in Ruby. It's a dynamic language. So what matters is if the object knows how to respond to a message (method).
