在Java中使用静态方法作为Kotlin中的扩展方法

Question

I have a static method declared in Java:

class X {
    public static void foo(Y y) { … }
}

I would love to use this method as extension method for instances of type Y in Kotlin:

import X.foo
…
y.foo()

Is that possible? I have control over all source code in question, eg to add annotations.

Answer 1

我不知道自动引用这些的方法，但编写自己的扩展只能包装现有的方法应该是可能的...

fun Y.foo() = X.foo(this)
