Kotlin反射怎样使用

import kotlin.reflect.KFunction
import kotlin.reflect.full.declaredFunctions
import kotlin.reflect.full.memberFunctions
import kotlin.reflect.jvm.kotlinFunction

data class MyClass(val name: String, val age: Int)

fun main() {
    val myInstance = MyClass("Alice", 30)
}

val myClass = MyClass::class
println("类名: ${myClass.name}")
println("主构造函数: ${myClass.primaryConstructor?.name}")

val declaredFunctions = myClass.declaredFunctions
val memberFunctions = myClass.memberFunctions

println("声明的函数:")
declaredFunctions.forEach { function ->
    println("\t${function.name}")
}

println("成员函数:")
memberFunctions.forEach { function ->
    println("\t${function.name}")
}

val myFunction = myClass.declaredFunctions.find { it.name == "myFunction" } as? KFunction<*> ?: run {
    println("找不到函数 myFunction")
    return
}

println("函数参数类型: ${myFunction.parameters.map { it.type }.joinToString(", ")}")
println("函数返回值类型: ${myFunction.returnType}")

// 调用函数
val result = myFunction.call(myInstance, "Bob", 25)
println("函数返回值: $result")
