Subject: what does :: do in this case?

Hi

This is in the Rails acts_as_list module but I think is a general Ruby
question. I don't understand the syntax of the ::#{self.name}
statement. I haven't seen :: without something preceding it. I think I
understand what this method enables the plugin to do: use the class
name in which the module is mixed.

Thanks,
Peter



module ActiveRecord
  module Acts
    module List

      def acts_as_list_class
        ::#{self.name}
      end

    end
  end
end
