Detailed Description

template<typename UserResult>
class helper::json::RapidReaderHandlerToStruct< UserResult >

This class is a adapter for Reader from RapidJson.

This class adapts std::map of strings (keys and values are strings) to be destination of text document conversion done be rapidjson::Reader. There are some constrains to what is converted:

• values from top level document are inserted into the map,
• value must be a simple type, sub objects, or arrays are ignored.
