如何在类中查找带注释的方法？

Question

给出一个注释

@Target(AnnotationTarget.FUNCTION)
@Retention(AnnotationRetention.RUNTIME)
annotation class MyAnnotation

如何使用此注释查找方法？

这是我得到了多远:

val cls = myObject.javaClass.kotlin
val found = cls.memberFunctions.filter { it.annotations.contains( ??? ) }

Answer 1

注释将是您的MyAnnotation类的实例.因此,您需要做的就是:

cls.memberFunctions.filter { it.annotations.any { anno -> anno is MyAnnotation } }
