JsonCpp: how to convert an unordered_map to Json::Value

Question

How to convert an unordered_map in C++ to Json::Value in JsonCpp?

For example I have a

unordered_map<std::string, std::string> map;

and I would like to convert it to Json::Value:

Json::Value myJson = ConvertToJson(map); // not a real code

How to do that?

Beware, Jsoncpp use a map to stroe data. So your unordered map will be ordered inside the Json::Value.

Here it is:

Json::Value ConvertToJson(std::unordered_map<std::string, std::string> map)
{
    Json::Value json;

    for(auto& element : map)
    {
        json[element.first] = element.second;

    }
    return json;
}
