hello - I have a question - can I use a Map with generics simmilar to that in kotlin?

val objects = FXCollections.observableHashMap<KClass<A: BasicModel>, ObservableList<A: BasicModel>>()

inline fun <reified T: BasicModel> get(): ObservableList<T> {
    return objects[T::class]
}

[kristofdho]

can you elaborate a bit on what you want / isn't working

[kristofdho]

val objects: ObservableMap<KClass<out BasicModel>, ObservableList<out BasicModel>> = FXCollections.observableHashMap()

inline fun <reified T: BasicModel> get(): ObservableList<T>? {
    @Suppress("UNCHECKED_CAST")
    return objects[T::class] as ObservableList<T>?
}

this is probably what you want? keep in mind that objects[T::class] returns a nullable

[kristofdho]

also specifying the type explicitly looks cleaner

Thanks - still trying to get used to slack 🙂 Ill try that.

Worked like a charm!
