Is there a nice way of accessing functions and/or variables (members in general) of a class without initializing it? I think it would be some kind of a singleton but I've only seen very complex approaches. Should be like an object but it's indeed a class.

object is literally that 😄. You still have to initialize the properties, otherwise they wouldn't have anything, but it's a singleton. See https://kotlinlang.org/docs/object-declarations.html#object-declarations-overview

Thanks but I need a class for the constructor.

[Toby]

Or is this the only possible lightweight way?

[ephemient]

there's tools like Objenesis which know a variety of hacks to instantiate objects without calling their constructor, but those uses are quite specialized. can you give an example of what are you trying to do?

[CLOVIS]

Why do you need a constructor, if you don't want to initialize the values?

[Roukanken]

Yeah you should clarify what exactly do you need:
because class does not have values in variables, and calling it's function (usaully) does not make sense without initializing it (as they work with the values in variables)

[Toby]

Sorry for my question lacking of information. I'm searching for an access for class members for an initialized class when I do not have access to the instance itself. The class is therefore initialized by a not accessible (future) source and I need to call some members.

[Roukanken]

The class is yours and only initialization is in future? Or future also provides the class?

[Toby]

I have access to the class but not the initialized class in a directly manner.

maybe a object or toplevel lateinit var could be used, the constructor (init block can assign that)
but that will only work if it will be initialized at most once

[Nikky]

you can also have all values that you need to initialize in the class be lateinit var and turn it into a object
initialization would then be done via method call instead of constructor

[Toby]

This is what I currently implement. Thanks.
