says I'm accidentally overriding a method with the same signature when I use

override val myProperty: MyPropertyClass; get() = super<A>.myProperty

you can’t override a method with a property

Is it a good convetion writing "val" variables with UPPERCASE in Kotlin? (Like i do for final variables in java )

no

UPPERCASE in java is for static final

not just final

ahaa, I do use uppercase for non-static final..maybe im not following a good java standard

but thanks!

so its been a while since i programmed C# and I dont remember being burned by this when I did, but I just spent 20 minutes debugging a problem where effectively what I had written was

val eventBus = google.guava.EventBus()

val event = generateEventIfDomainLogic();
//return type from generateIfDomainLogic is an Optional<Event> _not_ an Event

<http://eventBus.post|eventBus.post>(event)

as you can probably tell by reading that, what I really wanted was

<http://eventBus.post|eventBus.post>(event.get())
//or maybe
event.ifPresent { <http://eventBus.post|eventBus.post>(it) }

can i ask that intelliJ add some syntax highlighting to suggest, in kotlin, that if you hve a local variable that is consumed by an

Object o

or

Any o

or

varags Object o

signature, it suggest, by an underline, that you give it an explicit type on definition?

ie something like

Copy code

val ~event~ = generateEventIfDomainLogic()

'event' is consumed without regard to its type, for safety its best to specify the type explicitly,

alt

+

enter

to explicitly make

Optional<Event>

Copy code

<http://eventBus.post|eventBus.post>(event):

of course if guava's event bus simply had a kotlin wrapper on it and my event factory simply used null instead of Optional.Empty, then kotlin would've given me that type error (assuming the guava wrapper accepted

Any

and not

Any?

i don't see how you could make it do that, but also not be annoying for the other more comon and completely valid cases

also, Optional is a stupid java/C#ism anyways

yeah im realizing that

but we've already built a fair whack of code on it

you might be able to write an extension function and use that instead, idk

but i don't even think that would help.

no i dont think so either

what are your valid use cases for calling a method with

fun doSomething(input : Any?){}

as a signature?

generally speaking only utility layer classes are going to have signatures that generic

serializers and, well event busses

and in any instance where you're calling such a method, particularly if you start to introduce functional concepts like

Future

and

Option

and

Eiether

you're going to want some protection that you dont serialize a future by accident

yeah i don't often use an Any...

mostly generics are used in things i've interacted with

How do I create getter and setter to my private variables in an object? #Kotlin

Kotlin does that automatically for you. Member vars are properties with getters and setters.

i may be asking for something not possible..but, is there a way to get some type safety back for an int field which would be set to one of an int enum ? the issue is that i can't actually use a class, because there'd be like, literally, a million objects

i'm not sure if it's possible to get any sort of type..hinting. maybe not necessarily safety, just a hint that "this is probably actually one of <this enum>"
