using C++11 attributes

Question

Could you please explain how to get information from attributes in C++? For example, I want to write C++ to python binding. For this I need to annotate all methods in class

Answer 1

Attributes (a new C++11 feature) are just a standardized syntax for compiler extensions. To do what you want you would need a compiler with the proper extensions. So far, I don't think any compiler even implements attribute syntax, much less any specific attributes for Python bindings.

Because they're intended for compiler extensions, there's no standard way of creating your own attributes, like you can with Java annotations or C# attributes. Of course, a compiler could provide this ability as an extension... ;)
