Kotlin: How to work with List casts: Unchecked Cast: kotlin.collections.List

Question

I want to write a function that returns every item in a List that is not the first or the last item (a via point). The function gets a generic List<*&g

Answer 1

I made a little variation to @hotkey answer when used to check Serializable to List objects :

    @Suppress("UNCHECKED_CAST")
    inline fun  Serializable.checkSerializableIsListOf() =
        if (this is List<*> && this.all { it is T })
          this as List
        else null
