通过枚举＆＃x27; field＆＃x27;通过Kotlin的反射

，很容易以kproperty或kproperty1这样的方式传递属性

inline fun <TRet, reified TOwner> getName(property: KProperty1<TOwner, TRet>): String {
    return "${TOwner::class.simpleName}.${property.name}"
}

：

class Example(val exampleName: String)

在Kotlin中：exipplename）将返回xpeame.examplename。

有什么办法用枚举做到这一点吗？

假设我有以下枚举类别：

enum class ExampleEnum { VALUE1, VALUE2 }

有什么方法可以获取exampleenum :: value1或涉及示例中的值的一些有用的反射对象？我本质上希望能够通过通过一个参数来访问声明的kClass（或Java类）以及在枚举中访问的字段。

替代方法是编写类似getName（exampleenum :: class，“ value1”）的内容，该是冗长的，并且在重构/重命名的情况下表现不佳。另外，请注意getName只是一个示例，实际用例更为笼统。

原文

In Kotlin, it's easy to pass a property as a KProperty or KProperty1 like this for example:

inline fun <TRet, reified TOwner> getName(property: KProperty1<TOwner, TRet>): String {
    return "${TOwner::class.simpleName}.${property.name}"
}

And then given the following type:

class Example(val exampleName: String)

I could call getName(Example::exampleName) which would return Example.exampleName.

Is there any way to do this with enums?

Say I had the following enum class:

enum class ExampleEnum { VALUE1, VALUE2 }

Is there any way to get ExampleEnum::VALUE1 or some useful reflection object about the values in ExampleEnum? I essentially want to be able to access the declaring KClass (or java class) and the field being accessed in the enum, just by passing one argument.

The alternative is to write something like getName(ExampleEnum::class, "VALUE1") which is verbose and doesn't play well with refactorings/renames. Also, please note the getName is just an example, the actual use case is a bit more general.
