Descripción detallada

template<typename BasicJsonType>
struct json_sax< BasicJsonType >

SAX interface.

This class describes the SAX interface used by nlohmann::json::sax_parse. Each function is called in different situations while the input is parsed. The boolean return value informs the parser whether to continue processing the input.
