Is it possible to have a reified T for this operator fun ? Or to know the T class at runtime ?

operator fun getValue(thisRef: Any?, property: KProperty<T>): T {

[ephemient]

an extension fun should work

[GUIGAL Allan]

I’m in a delegated property, can you make extension fun with the operator keyword ?

[ephemient]

yes

[GUIGAL Allan]

What would you extend ? Thanks for the idea but I’m not sure how to put it

[ephemient]

an example: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/get-value.html which allows you to write val foo by ::bar

[ephemient]

because ::bar is a KProperty that is the receiver

[GUIGAL Allan]

I see, I give a whole class tho “var foo: MyObject by MongoField” with a couple more operators inside and it looks like I can’t have the extension fun one inside

[GUIGAL Allan]

“Property delegate must have a ‘setValue(User, KProperty*>, *)’ method. None of the following functions are suitable.”

Also you can create delegate in inline method

[turansky]

val a by myDelegate<String>()

inline fun <reified ...> myDelegate(): ReadOnlyProperty<..., T> = MyDelegate(T::class)

[turansky]

Inline setValue works inside delegate too
