如何使用Java的泛型泛型调用Kotlin方法? [英] How can I call Kotlin methods with reified generics from Java?

问题描述

我在Kotlin中使用以下方法:

I have the following method in Kotlin:

inline fun <reified T> foo() {

}

如果我尝试像这样从Java调用它:

If I try to call this from Java like this:

myObject.foo();

或者像这样:

myObject.<SomeClass>foo();

我收到以下错误:

java:foo()在MyClass中具有私有访问权限

java: foo() has private access in MyClass

如何从Java调用foo方法?

How can I call the foo method from Java?

推荐答案

无法使用Java中的类型化参数调用Kotlin inline函数，因为它们必须在调用站点进行转换和内联(在您的情况下，T应该在每个调用站点上用实际的类型替换，但是inline函数的编译器逻辑远不止于此)，并且Java编译器完全不会意识到这一点.

There's no way to call Kotlin inline functions with reified type parameters from Java because they must be transformed and inlined at the call sites (in your case, T should be substituted with the actual type at each call site, but there's much more compiler logic for inline functions than just this), and the Java compiler is, expectedly, completely unaware of that.
