You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: notification.rb
    path of file: ./repos/truffleruby/lib/gems/gems/test-unit-3.5.7/lib/test/unit
    
    the code of the file until where you have to start completion: require 'test/unit/util/backtracefilter'

module Test
  module Unit
    class Notification
      include Util::BacktraceFilter
      attr_reader :te
    
      def handle_notified_error(exception)
        return false unless exception.is_a?(NotifiedError)
        notification = Notification.new(name,
                                        filter_backtrace(exception.backtrace),
                                        exception.message)
        add_notification(notification)
        true
      end
