问题描述

Kotlin中 external 关键字的用途是什么?

What exactly is the purpose of the external keyword in Kotlin?

我想它像Java中的native一样用于JNI，但是我似乎找不到任何实际的参考文献或文档.

I guess it's for JNI like native in Java, but I can't seem to find any actual reference or documentation on this.

实际上，它等同于Java的native.文档中目前缺少它，但是有一个问题可以添加.

Indeed, it's an equivalent of Java's native. It's currently missing from the documentation but there's an issue to add it.
