Tim Crews created THRIFT-5843:
---------------------------------
Summary: Represent Thrift enums as C++ enum classes
Key: THRIFT-5843
URL: https://issues.apache.org/jira/browse/THRIFT-5843
Project: Thrift
Issue Type: Improvement
Components: C++ - Compiler
Affects Versions: 0.21.0
Reporter: Tim Crews
Add a cpp:enum_classes option to the C++ compiler so that a Thrift enum
declaration like this:
{{enum PrintDirection
{
Down = 68,
Up = 85
}}}
becomes a C++ [scoped
enumeration|https://en.cppreference.com/w/cpp/language/enum#Scoped_enumerations]
declaration like this:
{{enum class PrintDirection {
Down = 68,
Up = 85
};}}
This is very similar to the existing cpp::pure_enums option, but it addresses
the drawback that all of the enumerators (the values like Down and Up) are in
the same namespace as the enumerators from other enum types.
I already have a working implementation of this feature that I have been using
on a private fork of Thrift for about five years, so the only work required
would be to prepare the pull request.
