On ObjectOrientation


Recently I stumbled over Steve Yegge's essay “Execution in the Kingdom of Nouns ” which reflects on the linguistic styles of programming philosophies. Really something to think about. The points stated in the essay are quite observable in code that comes my way.

One nicely wrought wreath from the many flowers out of the Garden of Object Oriented Design Patterns is the following:


For the lack of a nail,
    throw new HorseshoeNailNotFoundException("no nails!");

For the lack of a horseshoe,
    EquestrianDoctor.getLocalInstance().getHorseDispatcher().shoot();

For the lack of a horse,
    RidersGuild.getRiderNotificationSubscriberList().getBroadcaster().run(
      new BroadcastMessage(StableFactory.getNullHorseInstance()));

For the lack of a rider,
    MessageDeliverySubsystem.getLogger().logDeliveryFailure(
      MessageFactory.getAbstractMessageInstance(
        new MessageMedium(MessageType.VERBAL),
        new MessageTransport(MessageTransportType.MOUNTED_RIDER),
        new MessageSessionDestination(BattleManager.getRoutingInfo(
                                        BattleLocation.NEAREST))),
      MessageFailureReasonCode.UNKNOWN_RIDER_FAILURE);

For the lack of a message,
    ((BattleNotificationSender)
      BattleResourceMediator.getMediatorInstance().getResource(
        BattleParticipant.PROXY_PARTICIPANT,
        BattleResource.BATTLE_NOTIFICATION_SENDER)).sendNotification(
          ((BattleNotificationBuilder)
            (BattleResourceMediator.getMediatorInstance().getResource(
            BattleOrganizer.getBattleParticipant(Battle.Participant.GOOD_GUYS),
            BattleResource.BATTLE_NOTIFICATION_BUILDER))).buildNotification(
              BattleOrganizer.getBattleState(BattleResult.BATTLE_LOST),
              BattleManager.getChainOfCommand().getCommandChainNotifier()));

For the lack of a battle,
    try {
        synchronized(BattleInformationRouterLock.getLockInstance()) {
          BattleInformationRouterLock.getLockInstance().wait();
        }
    } catch (InterruptedException ix) {
      if (BattleSessionManager.getBattleStatus(
           BattleResource.getLocalizedBattleResource(Locale.getDefault()),
           BattleContext.createContext(
             Kingdom.getMasterBattleCoordinatorInstance(
               new TweedleBeetlePuddlePaddleBattle()).populate(
                 RegionManager.getArmpitProvince(Armpit.LEFTMOST)))) ==
          BattleStatus.LOST) {
        if (LOGGER.isLoggable(Level.TOTALLY_SCREWED)) {
          LOGGER.logScrewage(BattleLogger.createBattleLogMessage(
            BattleStatusFormatter.format(BattleStatus.LOST_WAR,
                                         Locale.getDefault())));
        }
      }
    }

For the lack of a war,
    new ServiceExecutionJoinPoint(
      DistributedQueryAnalyzer.forwardQueryResult(
        NotificationSchemaManager.getAbstractSchemaMapper(
          new PublishSubscribeNotificationSchema()).getSchemaProxy().
            executePublishSubscribeQueryPlan(
              NotificationSchema.ALERT,
              new NotificationSchemaPriority(SchemaPriority.MAX_PRIORITY),
              new PublisherMessage(MessageFactory.getAbstractMessage(
                MessageType.WRITTEN,
                new MessageTransport(MessageTransportType.WOUNDED_SURVIVOR),
                new MessageSessionDestination(
                  DestinationManager.getNullDestinationForQueryPlan()))),
              DistributedWarMachine.getPartyRoleManager().getRegisteredParties(
                PartyRoleManager.PARTY_KING ||
                PartyRoleManager.PARTY_GENERAL ||
                PartyRoleManager.PARTY_AMBASSADOR)).getQueryResult(),
        PriorityMessageDispatcher.getPriorityDispatchInstance())).
      waitForService();
