i am a Java Android Developer and i'm approaching to Kotlin

I have defined the following class:

open class Player : RealmObject() {
    ...
}

And i defined the following two extensions, one for the generic RealmObject class and one for the specific Player class:

fun RealmObject.store() {
    Realm.getDefaultInstance().use { realm ->
        realm.beginTransaction()
        realm.copyToRealmOrUpdate(this)
        realm.commitTransaction()
    }
}

fun Player.store(){
    this.loggedAt = Date()
    (this as RealmObject).store()
}

What i want is if i call .store() on any RealmObject object, the RelamObject.store() extension will be called BUT if i call .store() on a Player instance the extension that will be called will be Player.store(). (No problem for now) I don't want to copy paste the same code, i love to write less reuse more. So i need that internally the Player.store() will call the generic RealmObject.store()

I got it. The code i wrote up there is actually working as expected :D

What i am asking is (just because i wrote that just by personally intuition):

Is this the good way?! Or there is some better way?

Thank you
