rapidjson::Document doc(rapidjson::kObjectType); rapidjson::Document::AllocatorType& allocator = doc.GetAllocator(); rapidjson::Value obj(rapidjson::kObjectType); obj.AddMember("name", "John", allocator); obj.AddMember("age", 32, allocator); doc.AddMember("person", obj, allocator); doc.RemoveMember("person"); obj.RemoveAllMembers(); obj.SetObject(); allocator.Clear();In this example, we again create a new document and obtain a reference to its allocator. We then add a new object to our document using this allocator. Next, we remove the member field we just added, clear the object's members, reset its value, and clear the allocator to deallocate memory associated with the object. Package library: RapidJSON Overall, the GetAllocator function is part of the RapidJSON package library, which provides an easy-to-use and efficient API for parsing and generating JSON documents in C++.
