  public static Function<List<Object>, Function> required = objects -> (Function<FunctionKeeper, Object>) (wrapper) -> {
    if (LIVRUtils.isNoValue(wrapper.getValue())) {
        return "REQUIRED";
    }
    return "";
};

How do I convert this Java8 lambda approach to Kotlin lambda?

  • wrapper is a function, isn't it? If yes, it has no method getValue(). Is that code correct? Commented Oct 11, 2018 at 20:27

Reset to default
1 
val required = { objects: List<Any> ->
    { wrapper: FunctionKeeper ->
        if (LIVRUtils.isNoValue(wrapper.value)) {
            "REQUIRED"
        } else {
            ""
        }
    }
}

Note that objects is not used in your function.
