Hey guys, is it possible to reference the value passed to a when expression using something similar to it?

In the code below “`it`” gets an error (Unresolved reference: it)

when(mCurrentUserType){

UserType.HUMAN -> {
setViewForUserType(currentUser, it)
}

UserType.ANIMAL -> {
setViewForUserType(currentUser, it)
}

}

you can just use mCurrentUserType

[dawidhyzy]

BTW. don’t use hungarian notation in Kotlin

@dawidhyzy
I feel so stupid I want to delete the question lol
But Is there a particular reason I can’t use it in this context? (Just to better understand my code)

As for hungarian notation, why?

[dawidhyzy]

There is no it in context

[dawidhyzy]

If you have method call in when you can creat val. For example

when (val response = executeRequest()) {
            is Success -> response.body
            is HttpError -> throw HttpException(response.status)
        }

[dawidhyzy]

because there is no benefit of hungarian notation

[dawidhyzy]

IDE marks properties

[dawidhyzy]

Kotlin creates getters/setters for properties
So if you access them on Java you will see `getMCurrentUserType`/`setMCurrentUserType`

Got it, thanks man! @dawidhyzy

[dawidhyzy]

no worries

[codeslubber]

@dawidhyzy you are saying don’t use Hungarian then you are showing mixed case var names, which is hungarian? are you just saying don’t embed the type in the name?

[dawidhyzy]

Which one are you referring to? It was just an example of what he will see from Java if he use m prefix for properties.

[Naveenkumar R]

In Systems Hungarian notation, the prefix encodes the actual data type of the variable. ---Wikipedia

Here, mCurrentUserType is following hungarian notation.
