Val namesQueueByLength = PriorityQueue(compareByLength)Ĭustomer.kt package. Val compareByLength: Comparator = compareBy To create Comparator, we use compareBy function. We need a Comparator that compares two Strings by their length. How about creating a Priority Queue of String items in which the String with the smallest length is processed first. Java Backend Development(Live) Android App Development with Kotlin(Live).

Val names: PriorityQueue = PriorityQueue() We create a data object with properties Name and Age, serialize it to JSON. – Priority Queue of String items: package Val nums: PriorityQueue = PriorityQueue() Then we remove one by one item from the Queues and see how the least element is removed first followed by the next least element and so on. We should note that the deleted value is also a String because JsonElement always saves its content as a String.We’re gonna create several Priority Queues and add some elements to them. "createdDate" to MapHelper.DATE_FORMAT.format(SERIALIZABLE_PROJECT.createdDate),

(value: T) Box.serializer () // Doesn't compile.

For classes with generic type parameters, serializer () function requires one additional argument per each generic type parameter: Serializable. Next, we can verify the result: val map = KotlinSerializationMapHelper.toMap(SERIALIZABLE_PROJECT) In this example, each pixel will be serialized using different data representation. Is JsonObject -> jsonObjectToMap(element) If we want to match this behavior in our toMap function, we could add a filtering step: fun toMapWithOnlyPrimar圜onstructorProperties(obj: T): Map

However, this string contains only the properties from the primary constructor: assertFalse(project.toString().contains(Project::description.name)) Kotlin Idioms Serializable and serialVersionUid in Kotlin Fastest Entity Framework Extensions Bulk Insert Bulk Delete Bulk Update Bulk Merge Example To create the serialVersionUID for a class in Kotlin you have a few options all involving adding a member to the companion object of the class. As we know, the default toString function of a data class will convert a data object to a string.
