如何引用外部对象的属性？

Question

考虑以下代码：

class SomeClass {

    companion object {
        val str = "My String"
        object AnotherObject {
             fun foo(str: String) {
                  return str + //companion object's str
             }
        }
    }
}

如何从

SomeClass::companion object::str

引用

AnotherObject::foo

？

请尝试如下：

class SomeClass {
    companion object {
        val str = "My String"
        object AnotherObject {
            fun foo(str: String): String {
                return str + SomeClass.str
            }
        }
    }
}
