Question

How do I choose a particular a method call in the inheritance chain?

class A
  def boo; puts "A:Boo"; end
end

class B < A
  def boo; super; puts "B:Boo"; end
end

class C < B
  def boo; self.A.boo(???); puts "C:Boo"; end
end

Thus the output would be A:Boo, C:Boo

TIA,

Answer 1

You can do

class C < B
  def boo
    A.instance_method(:boo).bind(self).call
    puts "C:Boo"
  end
end

However if you need this, that’s usually an indicator that you should rethink your design. In particular if C needs A’s implementation of boo, maybe B should not override it.
