Get list of option from enum

[Fabio Ravera]

Hi everyone!
I have a message containing an enum and I would like to extract the values in order to provide the user with the list of available options. Is it something that can be done or should I choose another approach?

I am using C++ and protobuf 3

Many thanks in advance!
Cheers,

Fabio

You should be able to get these values from the EnumDescriptor::value() method.
