Question

Is it possible to remove some of the inherited methods in Ruby? I mean, I can override it, but is there any other way?

Class ABC
end

a = ABC.new

puts a.id

Here, the method id is inherited from Object along with other methods like tap,class,type etc. I want to remove such methods.

Edit: I’m using Ruby 1.8.7

Answer 1

Yes – undef_method :foo will prevent any calls to the method foo (contrasted with remove_method :foo, which removes the method from the child, but still passes through up the inheritance chain).

Once again, though, why do you want to remove things like id?
