A JSON representation and parsing library.
The JSON library contains data types to represent a JSON data structure (Value, Object and Array), and a JSON parser.
Usage example:
Json::Object result; Json::parse("{ " " \"a\": \"That's great\", " " \"b\": true " "}", result); std::cerr << "Size: " << result.size(); << std::endl; // Size: 2 WString s = result.get("a"); bool b = result.get("b"); std::cerr << "a: " << s << ", b: " << b << std::endl; // a: That's great, b: true
enum Wt::Json::Type |
Enumeration for the type of a JSON value.
void Wt::Json::parse | ( | const std::string & | input, |
Value & | result, | ||
bool | validateUTF8 = true |
||
) |
Parse function.
This function parses the input string (which represents a UTF-8 JSON-encoded data structure) into the result
value. On success, the result value contains either an Array or Object.
If validateUTF8 is true, the parser will sanitize (security scan for invalid UTF-8) the UTF-8 input string before parsing starts.
ParseError | when the input is not a correct JSON structure. |
bool Wt::Json::parse | ( | const std::string & | input, |
Value & | result, | ||
ParseError & | error, | ||
bool | validateUTF8 = true |
||
) |
Parse function.
This function parses the input string (which represents a UTF-8 JSON-encoded data structure) into the result
value. On success, the result value contains either an Array or Object.
If validateUTF8 is true, the parser will sanitize (security scan for invalid UTF-8) the UTF-8 input string before parsing starts.
This method returns true
if the parse was succesful, or reports an error in into the error
value otherwise.
void Wt::Json::parse | ( | const std::string & | input, |
Object & | result, | ||
bool | validateUTF8 = true |
||
) |
Parse function.
This function parses the input string (which represents a UTF-8 JSON-encoded data structure) into the result
object.
If validateUTF8 is true, the parser will sanitize (security scan for invalid UTF-8) the UTF-8 input string before parsing starts.
ParseError | when the input is not a correct JSON structure. |
TypeException | when the JSON structure does not represent an Object. |
