Say I have something like

abstract class MyClass {
    var myVar = 1.0
        protected set
}

Can you make the setter of

myVar

public in a derived class without making

myVar

open?

What are you trying to do?

I'm just messing with ideas. Such a thing is easy to do in Java (e.g. make the getter final but the setter open), so I was wondering if there was a direct Kotlin equivalent.

is there a function to make a string JSON safe ?

this is my code: engine.executeScript("cy.add([{ group: \"nodes\", data: {id: \"${node_name}\"}}]);")

I want to make node_name safe

@bjonnh what do you mean with safe?

quoted

I could import a whole JSON library though

@bjonnh IIRC there is no such function in the stdlib, you need to use a JSON-library to do that

@Ruckus I'm surprised to see that

open get

doesn't work.

That was my original idea as well, but it indeed doesn't.

does anybody have some examples of kotlin idiomatic code to handle bounded decimal or integer conversion? Case in point, Ive effectively got a pojo

data class ViewObject(val amount: Double, val unit: TimeUnit)

and I want to convert it into a

java.time.Duration

class and back again, and I would like to make this class non-nullable where the default is something like

ViewObject(Double.INFINITY, TimeUnit.MINUTES)

where the presentation logic would represent "infinity" as empty string... maybe ill just use null 😕

What are the steps for creating a Java platform module from a Kotlin program?

Is it possible to delegate a property to another property in other way than this?

var someAttribute: AttributeClass
        get() = delegate.someAttribute
        set(value) {
            delegate.someAttribute = value
        }

can't you use

by

?

I’d like to but I didn’t find any applicable delegate 🙂

Hmm

by

requires a delegate and the attriute itself it not a delegate

If you have an interface that defines just this attribute you could implement that interface by delegation (

class MyClass : MyInterface by delegate

). However if that is not the case, you have do it the way you are doing currently I think.

No, I’d like to proxy that interface, it has more methods I don’t want to publish

@diesieben07 Yes, but it looks ugly 🙂

The proposal for this: https://youtrack.jetbrains.com/issue/KT-8658

is it possible in Kotlin to override standard library functions like

print

or

println

?

No, you need to write your own delegate if you want that

@Paul Woitaschek uploaded a file: Untitled

print is just a function

@Paul Woitaschek will using a delegate allow me to change the output of print statements in the code-base? let's say I do

print("blah")

now I want it to print

kotlin.io.print("$date - $message"

) every time somone calls regular print or println

On the JVM you could use

System.setOut

.

But it sounds like you want a logging library.
