default form helper

On line 1152 of form_helper.rb, there is this line:

        def default_form_builder           builder = ActionView::Base.default_form_builder           builder.respond_to?(:constantize) ? builder.constantize : builder         end

I tried searching for default_form_builder on ActiveView::Base but couldnt find the definition. Can anyone guide to where it's defined, specifically file and line number?

Ok, nevermined, it appears when Active support loaded, its defined as a class method on actionview:

ActiveSupport.on_load(:action_view) do     cattr_accessor(:default_form_builder) { ::ActionView::Helpers::FormBuilder }   end
