是否可以从Java访问Kotlin类型别名? [英] Is it possible to access a Kotlin typealias from Java?

问题描述

假设我有一个Kotlin 1.1 typealias，用于像这样的Kotlin函数类型

Suppose I have a Kotlin 1.1 typealias for a Kotlin function type like this

typealias Consumer<T> = (T) -> Unit

我可以通过Java来访问它

I can access this from Java as

import kotlin.Unit;
import kotlin.jvm.functions.Function1;

Function1<? super T, Unit> action = ...

是否可以通过Java以Kotlin类型别名(即Consumer)访问Kotlin Function1接口?

Is it somehow possible to access the Kotlin Function1 interface from Java under its Kotlin typealias name (i.e., Consumer)?

推荐答案

来自 KEEP建议用于类型别名:

NB Java没有类型别名"的概念，并且在类成员签名中看不到它们.

NB Java has no concept of "type aliases" and can't see them in class member signatures.

因此，不能，您不能使用Java中的类型别名，您只会在Kotlin中看到具有类型别名类型的任何参数或变量的实际类型.

So no, you can't use typealiases from Java, you'll just see the actual types of any parameter or variable that has a typealias'd type in Kotlin.
