QUESTION

Interpret an integer as Python enum flags

Asked 2021-Feb-26 at 05:40

I asked this question in interpret an integer as enum flags but did not state the challenge as clearly as I should have. I am looking for how to take a pure integer, not an instance of a class based on Flags, and interpret the integer according to the definitions in the class.

Suppose I have a Flag enum like this:

You can iterate through the possible flags & evaluate if the corresponding bit is set. Use the enum value for the check. And then you can access the .name attribute of the enum object to get the name associated with the value

Like so:

How to pass multiple enum with flags values to a XAML value and still keeping compile time type checking

Asked 2019-Nov-28 at 22:00

A partial answer exists here: WPF Multiple Enum Flags to Converter Parameter? where the proposed solution does loose the compile time type checking because it uses string values instead of real enum values. That could lead to error at runtime.

Additional information for experienced developers: This is the same problem that exists for many years about the INotifyPropertyChange before nameof exists, or lamda's for an alternate soso alternative.

Actually we can pass one enum parameter as: ConverterParameter={x:Static module:MyEnum.MyEnumValue} and still keeping compile time type checking.

But how to keep compile time type checking for multiples enum with flags values in XAML?

Example of what I would like to do:

QUESTION

64-bit enum flag in Internet Explorer 11

Asked 2018-Apr-23 at 14:38

We are sending a 64-bit enum from our C# back-end to our clients browsers via Web API 2. One of the requirements for the application is that it should run on Windows 10 x64 with ie11. However when I start ie11 I get two processes, one 64-bit and one 32-bit by default. Will a 64-bit enum work with ie11 or not? We do not wan't to go with the enum option if it can't handle more than 32 flags.

We are using TypeScript to handle flags and compiling it to ES5 with Webpack.

What are enum Flags in TypeScript?

We use TypeLITE to generate TypeScript definitions.

Browser process bitness doesn't matter here at all. But what matters is javascript doesn't have such thing as 64-bit integer. Javascript has number type, which is basically C# double. For that reason, javascript cannot safely represent integers bigger than 2^53-1 (Number.MAX_SAFE_INTEGER constant). Also all bit operators (<<, | etc) work with numbers as 32-bit integers, which also doesn't help this situation. For example, 1 << 32 evaluates to 1 in javascript.

So your 64-bit typescript enum is a minefield which will lead to potentially hard to detect bugs, and for that reason I'd avoid it.

If you cannot avoid it - you have to use some library which is able to work with 64-bit numbers, such as BigJS (but then I suppose you cannot use typescript enum).

What are pros/cons of usage bitsets over enum flags?

ANSWER

Answered 2017-Aug-07 at 09:10

Do you compile with optimization on? It is very unlikely that there is a 24x speed factor.

To me, bitset is superior, because it manages space for you:

can be extended as much as wanted. If you have a lot of flags, you may run out of space in the int/long long version.
may take less space, if you only use just several flags (it can fit in an unsigned char/unsigned short - I'm not sure that implementations apply this optimization, though)
