fetchMap（）をRecordMapperでどのように使用できますか？

Question

私は、このようなマップ何かフェッチすることができます知っている：

this.ctx.select(
     shopSubscription.field(SHOP_SUBSCRIPTION.SHOP_ID), 
     shopSubscription.field(SHOP_SUBSCRIPTION.PAYMENT_GATEWAY_SUBSCRIPTION_ID), 
     shopSubscription.field(SHOP_SUBSCRIPTION.ADMIN_TOOL_FEATURE_TYPE_ID), 
     PAYMENT_GATEWAY_SUBSCRIPTION.SUBSCRIPTION_ID_TOKEN 
     ) 
    .from(PAYMENT_GATEWAY_SUBSCRIPTION) 
     .join(shopSubscription) 
      .on(PAYMENT_GATEWAY_SUBSCRIPTION.ID.eq(shopSubscription.field(SHOP_SUBSCRIPTION.PAYMENT_GATEWAY_SUBSCRIPTION_ID)) 
        .and(PAYMENT_GATEWAY_SUBSCRIPTION.PAYMENT_GATEWAY_TYPE_ID.eq(paymentGatewayType))) 
     .fetchMap(PAYMENT_GATEWAY_SUBSCRIPTION.PAYMENT_GATEWAY_TYPE_ID, ShopSubscriptionDTO.class); 

を私はさらにこのクエリにRecordMapperを追加することができれば、私は好むコンパイル時に問題を検出します。

fetchMap()を呼び出す方法はありますが、RecordMapperも提供していますか？私はこのようになりますと思って何

：あまりにfetchMap(Field<K>, RecordMapper<? super R, R>)があることを私は見ていなかったfetchMap()の異なる実装のかなり多くがある

this.ctx.select(
     shopSubscription.field(SHOP_SUBSCRIPTION.SHOP_ID), 
     shopSubscription.field(SHOP_SUBSCRIPTION.PAYMENT_GATEWAY_SUBSCRIPTION_ID), 
     shopSubscription.field(SHOP_SUBSCRIPTION.ADMIN_TOOL_FEATURE_TYPE_ID), 
     PAYMENT_GATEWAY_SUBSCRIPTION.SUBSCRIPTION_ID_TOKEN 
     ) 
    .from(PAYMENT_GATEWAY_SUBSCRIPTION) 
     .join(shopSubscription) 
      .on(PAYMENT_GATEWAY_SUBSCRIPTION.ID.eq(shopSubscription.field(SHOP_SUBSCRIPTION.PAYMENT_GATEWAY_SUBSCRIPTION_ID)) 
        .and(PAYMENT_GATEWAY_SUBSCRIPTION.PAYMENT_GATEWAY_TYPE_ID.eq(paymentGatewayType))) 

     // For each record apply the map() function 

     .map(new RecordMapper<Record<?>, ShopSubscriptionDTO>() { 
      @Override 
      public ShopSubscriptionDTO map(Record<?> record) { 
       ShopSubscriptionDTO shopSubscriptionDto = new ShopSubscriptionDTO(); 

       shopSubscriptionDto.setShopId(record.getValue(SHOP_SUBSCRIPTION.SHOP_ID) 
       // ... 

       return shopSubscriptionDto; 
      } 
     }); 

     // Fetch the result into a map where the key is SHOP_SUBSCRIPTION.ADMIN_TOOL_FEATURE_TYPE_ID 
     .fetchMap(SHOP_SUBSCRIPTION.ADMIN_TOOL_FEATURE_TYPE_ID);
