如何从DAO中脱颖而出? [英] how to get Deffered from DAO?

问题描述

我想让DAO带来的Kotlin Coroutnies

I want to get Kotlin Coroutnies Deffered from DAO

@Query("select * from gameprocess where cabinId = :cabinId ")
fun getAllGameProccesBiCabin(cabinId :Int) : Deferred<GameProcess>

但是它不能编译(房间不知道如何处理Deffered)，但是我需要使用'Deffered'中的'wait'怎么做?

but it does not compile (room does not know how to handle Deffered), but I need to use 'wait' from 'Deffered' how can do this?

作为另一个选项，我可以使用本文中的扩展功能，但是，不知道如何将其集成到dao中:

as another option I could use extension function from this post but, dont know how to integrate it into dao:

推荐答案

这里是依赖项，它使我可以使用async{}.await

here is dependency which allows me to use async{}.await https://github.com/Kotlin/kotlinx.coroutines/blob/master/ui/coroutines-guide-ui.md

问题是我使用的是不支持它的旧版本.

The problem was that I was using old version which doesn't support it.
