or if bitmap is not allowed to be null

if (bitmap != null) ...

or was just it an example to test the snippet?

That’s just a test code

oh ok

it’s more complex, I have 5 variables to do the null check, if any of them is null, just

return

I see

there's one way to make that snippet work

but it's pretty awful

if you modify the

ifNotNull

to

if ( args.all{ it != null}) block(args)

right now, I’m using this way:

a?.let { a ->
    b?.let { b->
        c?.let { c->
            // doSomething 
        }
    }
}

pretty bad

you are able to access the args from the block using

it[0] as yourType

, but I'd definitely not do it

ehh… not good

are those class properties or method calls?

properties

I see, that makes things trickier

They are all initialized at some point (not in constructor), after that, they all should be not-null

can't you define them as lateinit then?

😅 looks crazy

hey, if it works...

right

just kidding haha

…

I know that's something that would be very hard to explain later

honestly, if you're sure the variables are initialized at the point you need them, that's the use case for

lateinit

you are right, I’ll try it with

lateinit

thanks!

hi all, how can i find out the name of a warning to suppress it with @Suppress? Currently i am looking for "This cast can never succeed" and "No cast needed". But I was also wondering how in general one could find the name of a warning. btw. in both cases, the ide is not offering to add a suppress annotation on Alt-Enter

I think it’s this one

@suppress("UNCHECKED_CAST")

I think they are enumerated here: https://github.com/JetBrains/kotlin/blob/master/compiler/frontend/src/org/jetbrains/kotlin/diagnostics/Errors.java
