template<> auto readMember(const JsonGenericValue& d, const char* tag, std::map<std::string, std::string>& val) -> bool: Specialization to handle reading a JSON object into an std::map<std::string, std::string>. Check passed json doc for existence of passed tag and verify it is an object. If present, populate passed val with key-value pairs in cell. Returns whether tag is found and successfully populated, or not. Logs an error if tag is found but is inappropriately configured.

Function documentation

bool fromJsonValue(const JsonGenericValue& obj, std::string& val)

Populate passed val with value. Returns whether successfully populated, or not. Logs an error if inappropriate type.

Parameters
obj	json value to parse
val	destination value to be populated
Returns	whether successful or not

template<>
bool readMember(const JsonGenericValue& d, const char* tag, std::map<std::string, std::string>& val)
