Ruby Socket Inheritance
- by Jarsen
I'm writing a Ruby class that extends TCPSocket. Assume it looks something like this:
class FooSocket < TCPSocket
def hello
puts 'hello'
end
end
I have a TCPServer listening for incoming connections
server = TCPServer.new 1234
socket = server.accept
When my server finally accepts a connection, it will return a TCPSocket. However, I want a FooSocket so that I can call socket.hello.
How can I change TCPSocket into a FooSocket?
I could duck-punch the methods and attributes I want directly onto the TCPSocket class, but I'm using it elsewhere and so I don't want to do that.
Probably the easiest solution is to write a class that encapsulates a TCPSocket, and just pass the socket returned by accept as a param. However, I'm interested to know how to do it through inheritance—I've been trying to bend my mind around it but can't figure it out.
Thanks in advance.
