Is there any way to be able to pass a condition based on a data class property as parameter? (thread)

[xii]

Maybe I'm overthinking this, but I thought it would be neat: I have a method which, in a step, does this:

val test = elements.findLast { it.isCondition }

[xii]

my idea is to make it.isCondition to be passed by parameter, so it could be
it.isConditionB
based on an argument

[xii]

but i'm not sure how to achieve it

[xii]

maybe passing a function as argument?

You can either pass in a property reference that returns a boolean like this: KProperty<Boolean> or alternatively you can pass in a transformation function that takes an element of your type and spits out a boolean

i tried passing a function as you mentioned, but i get

[xii]

Expression '' of type 'Function<Boolean>' cannot be invoked as a function. The function 'invoke()' is not found

Have it as `transformer: (ItemType) -> Boolean

sorry i couldnt respond any more yesterday

[xii]

that syntax doesnt work for me, but simply changing the parameter declaration to (itemType) -> Boolean instead of Function<Boolean> worked

thank you 🙂
