Kotlin provides the reified enumValues function to get all instances of Enum<T>: fun <reified T : Enum<T>> enumValues(): Array<T>Copy The third requirement is also a little bit challenging. This is because each enum may name the property differently: enum class NumberV4(val value: Int...
自Kotlin 1.1 起,可以使用 enumValues<T>() 和enumValueOf<T>() 函数以泛型的方式访问枚举类中的常量。 1.4.1、访问枚举变量属性 例: fun main(args: Array<String>) { println("name = " + Color.RED.name + "\tordinal = " + Color.RED.ordinal) println("name = " + Color.WHITE.name + "...

Enumerations inKotlinare data types that hold a set of constants. Enums are defined by adding the modifierenumin front of aclassas shown below. Yes, in Kotlin,Enums are classes. Kotlin中的枚举是保存一组常量的数据类型。 枚举是通过将改性剂定义enum在前面类,如下所示。 是的,在Kotlin中,枚举...
we saw how to achieve this usingkotlinx.serialization, Jackson, and Gson in Kotlin. Jackson is the only solution with something built in to handle this, but we can achieve similar results with custom serializers inkotlinx.serializationand Gson. This ensures our applications remain resilient even...
Kotlin Enum - Enum is a special data type that allows a variable to hold a value only from a set of predefined constants. In this tutorial, learn about Kotlin Enum Class : Syntax, Initialization, how enum classes are different from regular classes. An ex

[Kotlin] Enum class enumclassColor { RED, GREEN, BLUE } fun main() { println(Color.GREEN)//GREEN} Or give enum a value: enumclassColor { RED(0xFF0000), GREEN(0x00FF00), BLUE(0x0000FF) } Give a method: enumclassColor(val rgb: Int) {...
