Subject: Determining if initialize is defined in child class

Hi

I am looking for a method that will tell me if a method
is defined in a child class. The problem is when looking
at child classes for with the parent has the method in
question defined.

  class C
    private_method_defined?(:fred) #=>  false
    private_method_defined?(:initialize) #=> true
  end

Is there some method that will return false for the above
initialize method:

  class C
    method_defined_in_this_class?(fred:) #=>  false
    method_defined_in_this_class?(:initialize) #=> false
    def fred; end
    method_defined_in_this_class?(fred:) #=>  true
  end

Ultimately I want to be able to do the following:

  class Parent
    def initialize; end
  end

  class Child < Parent
    method_defined_in_this_class?(:initialize) #=> false
  end
