Actually you can do it. asdict has keyword argument dict_factory which allows you to handle your data there: from dataclasses import dataclass, asdict from enum import Enum @dataclass class Foobar: name: str template: “FoobarEnum” class FoobarEnum(Enum): FIRST = “foobar” SECOND = “baz” def custom_asdict_factory(data): def convert_value(obj): if isinstance(obj, Enum): return obj.value return obj return dict((k, … Read more
for future googlers! finally i managed to solve the problem, i just had to put the annotations somewhere else in my code , @ElementCollection(targetClass = Days.class) @CollectionTable(name = “days”, joinColumns = @JoinColumn(name = “rule_id”)) @Column(name = “daysOfWeek”, nullable = false) @Enumerated(EnumType.STRING) public Set<Days> getDays() { return days; } as you can see i wrote the … Read more
It’s worth pointing out that you don’t need a typedef. You can just do it like the following enum strategy { RANDOM, IMMEDIATE, SEARCH }; enum strategy my_strategy = IMMEDIATE; It’s a style question whether you prefer typedef. Without it, if you want to refer to the enumeration type, you need to use enum strategy. … Read more
Do you actually need the numeric values at all? If not then you could use something like this: const TEST_ERROR = { SUCCESS : ‘Success’, FAIL : ‘Fail’, ID_ERROR : ‘ID Error’ }; Object.freeze(TEST_ERROR)
I also had this problem. Easy way to get around it: add a + sign before your variable in the switch, i.e. switch (+editMode) { case EditMode.Delete: … break; case EditMode.Edit: … break; default: … break; }
Magic Enum header-only library provides static reflection for enums (to string, from string, iteration) for C++17. #include <magic_enum.hpp> enum Color { RED = 2, BLUE = 4, GREEN = 8 }; Color color = Color::RED; auto color_name = magic_enum::enum_name(color); // color_name -> “RED” std::string color_name{“GREEN”}; auto color = magic_enum::enum_cast<Color>(color_name) if (color.has_value()) { // color.value() -> … Read more
C++ has two kinds of enum: enum classes Plain enums Here are a couple of examples on how to declare them: enum class Color { red, green, blue }; // enum class enum Animal { dog, cat, bird, human }; // plain enum What is the difference between the two? enum classes – enumerator names … Read more
Good question – I was surprised that the first and third lines worked. However, they are supported in the C# language specification – in section 7.8.4, it talks about enumeration addition: Every enumeration type implicitly provides the following pre-defined operators, where E is the enum type and U is the underlying type of E: E … Read more
This is a bug. Here’s the specified behavior for a switch statement according to the Java Language Specification, 3rd Edition: JLS 14.11 The switch Statement SwitchStatement: switch ( Expression ) SwitchBlock When the switch statement is executed, first the Expression is evaluated. If the Expression evaluates to null, a NullPointerException is thrown and the entire … Read more
