说得对,1.3 新增了一个类来支持大于22的情况:
/** * A function that takes N >= 23 arguments. * * This interface must only be used in Java sources to reference a Kotlin function type with more than 22 arguments. */ @SinceKotlin("1.3") interface FunctionN<out R> : Function<R>, FunctionBase<R> { /** * Invokes the function with the specified arguments. * * Must **throw exception** if the length of passed [args] is not equal to the parameter count returned by [arity]. * * @param args arguments to the function */ operator fun invoke(vararg args: Any?): R /** * Returns the number of arguments that must be passed to this function. */ override val arity: Int }
