Functions: appendJSONKey, appendJSONString, appendJSONValue, containerToJSON, isJSONString
Functions
appendJSONKey
void appendJSONKey(
std::string & val,
const Var & any
);
Converts the any to a JSON key (i.e. wraps it into double quotes regardless of the underlying type) and appends it to val.
appendJSONString
void appendJSONString(
std::string & val,
const Var & any
);
Converts the any to a JSON string (i.e. wraps it into double quotes) regardless of the underlying type) and appends it to val.
appendJSONValue
void appendJSONValue(
std::string & val,
const Var & any,
bool wrap = true
);
Converts the any to a JSON value (if underlying type qualifies as string - see isJSONString() - it is wrapped into double quotes) and appends it to val. Wrapping can be prevented (useful for appending JSON fragments) by setting the wrap argument to false.
containerToJSON 
template < typename C > void containerToJSON(
C & cont,
std::string & val
);
isJSONString
bool isJSONString(
const Var & any
);
Returns true for values that should be JSON-formatted as string.
