Kotlin:从类对象获取超类-对象推断错误
下面的代码应该遍历所传递对象类的超类链,直到到达顶层Kotlin:从类对象获取超类-对象推断错误,kotlin,Kotlin,下面的代码应该遍历所传递对象类的超类链,直到到达顶层 protected fun getBestMethodFor(o: Any): Method? { val nodeClass = o.javaClass val objectClass = Any::class.java ... // Go through superclasses. var c = nodeClass while (c != objectClass && a
protected fun getBestMethodFor(o: Any): Method? {
val nodeClass = o.javaClass
val objectClass = Any::class.java
...
// Go through superclasses.
var c = nodeClass
while (c != objectClass && ans == null) {
debugMsg("Looking for class match for " + c.name)
...
c = c.superclass
}
...
}
这将导致两个错误:
Error:(57, 17) Kotlin: Type mismatch: inferred type is Class<in Any!>! but Class<Any> was expected
Error:(57, 19) Kotlin: Type inference failed. Expected type mismatch: inferred type is Class<in Any!>! but Class<Any> was expected
错误:(57,17)Kotlin:类型不匹配:推断的类型是类!但上课是意料之中的
错误:(57,19)Kotlin:类型推断失败。预期类型不匹配:推断类型为类!但上课是意料之中的
为什么会失败,我需要做什么改变来解决这个问题
注意:代码是使用IntelliJ的转换器从Java自动转换而来的。在Java中,返回类
