enums

Is changing the number of an enum a breaking change?

Consider the following code: public enum SomeCode { NIF = 0 ,NIE = 1 ,CIF = 2 ,PAS = 3 ,NIN = 4 ,SSN = 5 ,OTH = 5 ,UKN = 6 } Would changing OTH = 5 to OTH = 7 be a breaking change? Edit: I never store the int value, only ever the text representation of the enum. It may be used in other DLLs, but wi...

Parent's Enum in Java

In the code example below, I'm trying to test the value of an enum in the parent class.

Can I pass an enum into a controller so the Model Binder binds it?

if so, how should i pass the parameter? would a string matching the enum name be ok? This would be handy if I was passing a dropdown box that matched enumerated items.

scanf() with C++ enums

The following is a typical situation in our codebase. enum ConfigOption { CONFIG_1=1, CONFIG_2=2, CONFIG_3=3 } ConfigOption cfg1, cfg2; sscanf(s, "%d", &cfg1); This is an internally used simulation software. Not distributed. Ease of maintenance and correctness are important. Portability and user interface -- not really. The troubl...

C# In() method? (like Sql)

Strange behavior of EnumMap with keys from different classloaders

I encountered strange behavior of enum type loaded by different class loader.

Convention dictates that the name of the source string property will be that of the enum property with a postfix of "Raw". By processed we mean we'll need to strip specified characters e.t.c. I've looked...

Best way to get all bits of an enum flag?
