This adds an additional template parameter which allows to set a custom base class for nlohmann::json. This class serves as an extension point and allows to add functionality to json node. Examples for such functionality might be metadata or additional member functions (e.g., visitors) or ...
是指将JSON数据映射到nlohmann json库中的结构数组对象。nlohmann json是一个开源的C++ JSON库,用于处理和操作JSON数据。 在nlohmann json库中,可以使用std::vector或std::array等容器类型来表示结构数组。结构数组是一个包含多个相同结构的元素的数组,每个元素都具有相同的属性和类型。
The package configuration file,nlohmann_jsonConfig.cmake, can be used either from an install tree or directly out of the build tree. Embedded To embed the library directly into an existing CMake project, place the entire source tree in a subdirectory and calladd_subdirectory()in yourCMakeLists...
