在Java中,没有与C#中的Flags属性完全等价的功能 代码语言:javascript 复制 public class EnumFlags { public static void main(String[] args) { System.out.println(Flags.A | Flags.B); // 输出: 3 } public enum Flags { A(1), B(2), C(4), D(8); private int value; Flags(int value) {...
EnumSet 是专用的 Set实现,用于与 Enum 类型一起使用。 与哈希集相比,由于内部使用了位矢量(internalBit Vector)表示,因此它是高效紧凑的Enum常数表示形式。它安全地替代了传统基于int 形的位标记 “bit flags”,使我们能够编写易读易维护的代码。 EnumSet是一个抽象类,它有两个实现:"RegularEnumSet"和"JumboEnumSet...
The space and time performance of this class should be good enough to allow its use as a high-quality, typesafe alternative to traditional int-based "bit flags." Even bulk operations (such as containsAll and retainAll) should run very quickly if their argument is also an enum set. ...
Compared to aHashSet,it’s a very efficient and compact representation of a particularSetofEnumconstants, owing to the internalBit Vector Representationthat’s used. It also provides a type-safe alternative to traditionalint-based “bit flags,” allowing us to write concise code that’s more re...
1、标注枚举属性:我们可以在枚举属性上使用JsonConverterAttribute特性来标注BgColor属性,并使用JsonStringEnumConverter转换器,如下: using System.Text.Json.Serialization; public class Circle { public double Radius { get; set; } [JsonConverter(typeof(JsonStringEnumConverter))] ...
