BP Graphs: Switch on Enum. For BP Graphs, one of the most wonderful things about ENUMS is the ability to use Switch on Enum() instead of having to do a series of branches and testing one value many times C++ .h File. You need to add the UENUM definition above your class and then actually create a member variable in your class that you want to
The first line finds a pointer to the enum object from its namespace, and then in the UE_LOG call, we use that enum pointer to get a string value to output. Important to note is that the pointer isn’t guaranteed to be valid, so use a ternary operator to ensure that you safely handle a

Magic Enum header-only library provides static reflection for enums (to string, from string, iteration) for C++17. #include
enumベスト アンサー · 19(The approach of the better_enums library) There is a way to do enum to string in current C++ that looks like this: ENUM(Channel, char, Red = 1,84For C++17 C++20, you will be interested in the work of the Reflection Study Group (SG7). There is a parallel series of papers covering wording71This is similar to Yuri Finkelstein; but does not required boost. I am using a map so you can assign any value to the enums, any order. Declaration24Back in 2011 I spent a weekend fine-tuning a macro-based solution and ended up never using it. My current procedure is to start Vim, copy the enum17I don’t know if you’re going to like this or not, I’m not pretty happy with this solution but it is a C++14 friendly approach because it is using t12If your enum looks like enum MyEnum
AAA = -8,
BBB = ‘8’,
CCC = AAA + BBB
You can move the content of the enum to a new file: AAA =7I had the same problem a couple of days ago. I couldn’t find any C++ solution without some weird macro magic, so I decided to write a CMake code g5Just generate your enums. Writing a generator for that purpose is about five minutes’ work. Generator code in java and python, super easy to port t4As per request from the OP, here a stripped down version of the ugly macro solution based on Boost Preprosessor and Variadic Macros .

Mar 04, 2007 · In Ada and probably numerous other languages, string representations of each enum value name are available in an elegant manner, and the language has built-in functions for converting between the actual value and the string representation, and vice versa. The language implementation is able to do this in an optimized manner as well. I suspect that it can’t be as easy as that in C++, given
Is there a simple way in C++ to convert a string to an enum (similar to Enum.Parse in C#)? A switch statement would be very long, so I was wondering if there is a simpler way to do this?. EDIT: Thanks for all of your replies. I realized that there was a much simpler way to do it for my particular case.
A std::map (or unordered_map ) could do it easily. Populating the map would be just as tedious as the switch statement though.ベスト アンサー · 27Use std::map and use boost::map_list_of to easily initialize it. Example, enum X
