#general can any one help me to get it work in the newer version

Perhaps you can set the "canchangeto" things in an initializer instead of in the constructors?

no idea about it. I am new to this. And the person who written the code is not in connection .

Any descriptive answer for the same?

@karelpeeters can you elaborate more how i can make it back to work

@hb2708 Make

canSwitchTo

a

val

, add an

init

block and set the values from there. (see https://kotlinlang.org/docs/reference/classes.html#constructors).

I'm not entirely sure that will work though.

That's the reason I only use destructing declaration for simple touples only

Sometimes it's ridiculous, I have a user entity which olds many fields about the user and I need to use the

heightUnit

from a lambda

Then it converts it to something like

-> (_,_,_,_,_,_,_,_,_,_,_,_heightUnit,_,_,_)

in kotlin i create two class to save money data with currencies.

data class Currency (val baseMoneySymbol: String, val baseMoneyName: String,
                     val moneyConversion: List<Money>, val date: String) {
    fun getSelectMoneyCurrency(selectMoney: String) : Money {
        moneyConversion.filter{
            (it.symbol == selectMoney)
        }.map {  return it}
        return Money(“”, 0.0)
    }

    fun size(): Int = moneyConversion.size

}

data class Money (val symbol: String, val currencyValue: Double)

The case is that I try to call the size function or the other within Currency and gives me the following error. “Error:(24, 20) Kotlin: Unresolved reference: size” How do I solve it? Thanks

It can't resolve

moneyConversion.size

?

Sidenote: you forgot you closing ' and iirc there is a

findFirstOrElse

method that you can use to simplify your code.

This code correct, not paste correctly

Yes, I can not solve that function. I do not understand what you mean I did not close the function properly.

Right the closing ` would be for the slack formatting.

I have to look at how that function works that you say I do not know. Thank you so much for everything!

I’ll find out, it sure sucks.

How can I add map like indexing to an arbitrary class?

val thing = SomeClass(); thing["hi"] = 5

overriding operator get

implement the

set

and

get

operators

Well.. I did that

I guess it can't be in the class body itself?

did you implemented it inside SomeClass or as an extension function?
