Faster JsonCpp alternative that allows copying/mutability of Json objects?

Question

JsonCpp is slow. And the code is pretty messy.

Is there any alternative that is faster, cleaner and supports stuff like:

Json::Value val, copy;
val[\         


        

Answer 1

After searching for some time the "documentation" I finally found a good way to copy JSON objects with rapidjson wich is very convenient:

rapidjson::Document doc; // This is the base document that you got from parsing etc
rapidjson::Value& v = doc["newMember"]; // newMember = 100

assert(v.GetInt() == 100);

rapidjson::Document copy;
doc.Accept(copy); // The accept meachnism is the same as used in parsing, but for copying

assert(copy["newMember"].GetInt() == doc["newMember"].GetInt())

The explicit copying has one advantage: It forces you to think clearly about when you are using references or potentially unnecessary copies.
