Hi, I’ve a class like this:

class Request  
attr\_accessor :method, :code  
def to\_s  
“#{method} #{code}”  
end  
end

So if I print directly an instance I see a string containing both  
attributes:

message = Request.new  
message.method = “INVITE”  
message.code = “200”  
puts message  
=\> “INVITE 200”

This is really nice but I’m not sure of how secure it’s. Could  
replacing “to\_s” method change any other behaviour?

Thanks.

It’s fine for your own classes.
