Is it possible to compare private attributes in Ruby?

Question

I\'m thinking in:

class X
    def new()
        @a = 1
    end
    def m( other ) 
         @a == other.@a
    end
end

x = X.new()
y = X.new()
x.m( y ) 
         


        

Answer 1

Not sure, but this might help:

Outside of the class, it's a little bit harder:

# Doesn't work:
irb -> a.@foo
SyntaxError: compile error
(irb):9: syntax error, unexpected tIVAR
        from (irb):9

# But you can access it this way:
irb -> a.instance_variable_get(:@foo)
    => []
