Reflection Kotlin jvm和Kotlin js之间KClass的不同行为

Reflection Kotlin jvm和Kotlin js之间KClass的不同行为,reflection,kotlin,kotlin-js,Reflection,Kotlin,Kotlin Js,我编写了一些kotlin代码来显示jvm和js上执行的行为差异。我怎样才能解决这个问题 此等式为:booleanKClass==genericKclass JVM是否为真 但JS的为false 我将粘贴代码,然后是控制台生成的输出(一个用于jvm,一个用于js) 如果您从多平台项目调用test1(),您将看到这一点,就像我所做的一样。 我使用的是kotlin_version='1.2.51' fun test1() { val values = PropertyDelegate()

我编写了一些kotlin代码来显示jvm和js上执行的行为差异。我怎样才能解决这个问题

此等式为:booleanKClass==genericKclass JVM是否为真 但JS的为false

我将粘贴代码,然后是控制台生成的输出(一个用于jvm,一个用于js) 如果您从多平台项目调用test1(),您将看到这一点,就像我所做的一样。 我使用的是kotlin_version='1.2.51'

fun test1() {
    val values = PropertyDelegate()
    val result = Result(values)
    println("This will call the delegate getter.")
    println("result.success is not really important but: ${result.success}")
    println("This will call the delegate setter...")
    result.success = true
    println("end")
}

class Result(del: PropertyDelegate) {
    var success: Boolean by del
}

class PropertyDelegate() {
    inline operator fun <reified T> getValue(thisRef: Any?, property: KProperty<*>): T {
        val booleanKClass = Boolean::class
        val genericKclass = T::class
        println("getValue (booleanKClass == genericKclass) is ${booleanKClass == genericKclass}")
        return true as T
    }

    inline operator fun <reified T> setValue(thisRef: Any?, property: KProperty<*>, value: T) {
        val booleanKClass = Boolean::class
        val genericKclass = T::class
        println("setValue (booleanKClass == genericKclass) is ${booleanKClass == genericKclass}")
    }
}
JS输出:

This will call the delegate getter.
getValue (booleanKClass == genericKclass) is false
result.success is not really important but: true
This will call the delegate setter...
setValue (booleanKClass == genericKclass) is false
end

自Kotlin 1.3.41以来,其工作方式与预期一致

印刷品:

This will call the delegate getter.
getValue (booleanKClass == genericKclass) is true
result.success is not really important but: true
This will call the delegate setter...
setValue (booleanKClass == genericKclass) is true
end

有趣。我不明白为什么这不应该起作用,即使在技术上有限制。在JS中,
genericKclass
显示为
class null
。请随意投票相关问题JFYI:问题已经解决。
