for loop range must have an iterator kotlin

Progressions represent the first element, the last element and the step which is non-zero. This is done by usingĪn arithmetic progression is represented by integral type progressions such as CharProgression, IntProgression, Long Progression. The operation performed in range is to check whether the element is contained in it or not. It contains two endpoints as start and end (endInclusive)points. It represents a closed mathematical interval defined for comparable types. To index a field, use the annotation Like primary keys, this makes writes slightly slower, but makes reads faster.A common interface in the library. Primary keys that are String types or boxed integers ( Byte, Short, Integer, and Long) can have the value null unless the annotation is combined with Indexing properties commitTransaction () // Listeners will be notified when data changes puppies. createObject ( 0 ) // Create managed objects directly person. copyToRealm ( dog ) // Persist unmanaged objects val person = realm. beginTransaction () val managedDog = realm. size // => 0 because no dogs have been added to the Realm yet // Persist your data in a transaction realm. getDefaultInstance () // Query Realm for all dogs younger than 2 years old val puppies = realm. init ( context ) // Get a Realm instance for this thread realm = Realm. age = 1 // Initialize Realm (just once per application) Realm. Use Realm objects like regular Kotlin objects val dog = Dog () dog. var dogs : RealmList = RealmList () ): RealmObject () //. var id : Long = 0, var name : String = '', var age : Int = 0, // Other objects in a one-to-one relation must also subclass RealmObject. var name : String = '', var age : Int = 0 ): RealmObject () open class Person ( // Properties can be annotated with PrimaryKey or Index. Non-nullable properties must be initialized // with non-null values. All properties are by default persisted. This // ensures that an empty constructor is generated. open class Dog ( // You can put properties in the constructor as long as // all of them are initialized with default values. You must annotate all classes with `open`. import io. import io. // Define your model classes by extending RealmObject. Import the Kotlin extensions for Realm.
