一、Kotlin中深拷贝的实现方式一 DeepCopy.kt 文件 , 内容如下: packagecom.stone.demo.basic.deepcopy1classDeepCopy{}interfaceDeepCopyable<outR>{fundeepCopy():R}// 一. kotlin实现对象的深度拷贝// 实现方式: 使用 直接 "创建对象" 的方式实现深度拷贝// 优点: 可以用于 "data-class" 和 "非data-c...
Function<*, String> , 代表 Function< in Nothing, String> ; Function< Int, *> , 代表 Function< Int, out Any?> ; Function<, > , 代表 Function< in Nothing, out Any?> 注意: 星号投射与 Java 的原生类型(raw type)非常类似, 但可以安全使用。 Kotlin 枚举类 枚举类最基本的用法是实现一个类...
Use Kotlin Reflection to provide an extension function forDeepCopyableso that any data class which implementsDeepCopyablecan simply calldeepCopy()to copy itsself. See the test code below: data classSpeaker(valname:String,valage:Int): DeepCopyabledata classTalk(valname:String,valspeaker:Speaker):...
The copy function also allows you to modify multiple parameters at once. This is especially useful in cases where you want to modify certain properties in multiple data classes in one go. Overall, the Kotlin data class copy feature is a great way to conveniently create copies of data classes...
This would have disappeared once we updated to Kotlin 2.1. JakeWharton requested a review from swankjesse September 24, 2024 04:09 Retain compiler-generated copy function 5f5add8 JakeWharton force-pushed the jw.copy.2024-09-24 branch from 5023140 to 5f5add8 Compare September 24, 2024 14:...
3. Customclone()function We can also implement our ownclone()function, instead of implementing theCloneableinterface and overriding itsclone()function. This is demonstrated below: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18
This article explores different ways to get a reverse copy of a list in Kotlin. The specified list may or may not be mutable, but the copy of the specified list must be mutable.1. Using reversed() functionThe standard solution is to call the ...
A deep copy creates a new object and recursively adds the copies of nested objects present in the original elements. Let’s continue with example 2. However, we are going to create deep copy using deepcopy() function present in copy module. The deep copy creates independent copy of original...
Let’s implement the deep clone of an object that contains a function and a Date() object to see a clearer picture of the problem.Add the new fields to the student1 object as in the example below.Example Code:let student1 = { name: 'kevin', age: function() { return 24; }, ...
