From an MSDN article: It is interesting to note that when Flags is specified, Parse and Format methods feature advanced capabilities. Likewise, the Parse method can successfully parse a comma-separated string like the one just shown into the proper numeric value.
Here is the full code: public enum Family { Brother, Sister, Father } public enum CarType { Volkswagen, Ferrari, BMW } static void Main(string[] args) { Console.WriteLine(GetEnumList<Family>()); Console.WriteLine(GetEnumList<Family>().First()); Console.ReadKey(); } private static List<T> GetEnumList<T>() { T[] array = (T[])Enum.GetValues(typeof(T)); List<T> list = new List<T>(array); return list; }
OpenAPI 3.1 OpenAPI 3.1 uses the latest JSON Schema, and the recommended way to annotate individual enum values in JSON Schema is to use oneOf+const instead of enum. This way you can specify both custom names (title) and descriptions for enum values. Severity: type: integer oneOf: – title: HIGH const: 2 description: An urgent problem … Read more
I wish enums were more powerful in .Net. And I love .Net! You can use attributes to accomplish the same thing. Write the code below once and use it everywhere. This will be a long answer but I think it’s a pretty good solution so have patience! Usage SomeEnum e = SomeEnum.ValueTwo; string description = … Read more
Start with INT_MIN on top like this: #include <limits.h> enum fruits { orange = INT_MIN, lemon, … } Per “5.2.4.2.1 Sizes of integer types ” and/or “Annex E/1” of the C11 Standard INT_MIN is at least -32767. INT_MIN gets defined by including <limits.h>.
I’ve found what I need. http://chrisjordan.ca/post/50865405944/custom-json-serialization-for-enums-using-jackson. It was 2 steps. Override the toString method of the Reos enum @Override public String toString() { return text; } Annotate with @JsonCreator the fromText method of the Reos enum. @JsonCreator public static Reos fromText(String text) And that’s all. I hope this could help others facing the same problem.
You can create an atomic enum like this: #include <atomic> enum Decision {stay,flee,dance}; std::atomic<Decision> emma_choice {stay}; // emma_choice is atomic You can also do the same thing with enum classes: #include <atomic> enum class Decision {stay,flee,dance}; std::atomic<Decision> emma_choice {Decision::stay}; // emma_choice is atomic
PostgreSQL doesn’t know how to automatically cast input of type text to input of type equipment. You have to explicitly declare your strings as being of type equipment: ARRAY[‘projector’,’PAsystem’,’safe’]::equipment[] I confirmed this with SQL Fiddle.
Python 3.6 has added Flag and IntFlag which support the usual bit-wise operations. As a bonus, the resulting values from the bit-wise operations are still members of the original flag class, and are singletons [1]. The aenum library also has this addition and is usable back to Python 2.7. [1] A bug exists in 3.6.0: … Read more
For many IDE’s now in 2022, the following will populate intellisense: class MyEnum(Enum): “”” MyEnum purpose and general doc string “”” VALUE = “Value” “”” This is the Value selection. Use this for Values “”” BUILD = “Build” “”” This is the Build selection. Use this for Buildings “”” Example in VSCode:
