QJson
the easiest way to manage JSON objects with Qt
JSON (JavaScript Object Notation) is a lightweight data-interchange format. It can represents integer, real number, string, an ordered sequence of value, and a collection of name/value pairs.
QJson is a qt-based library that maps JSON data to QVariant objects: JSON arrays will be mapped to QVariantList instances, while JSON objects will be mapped to QVariantMap.
Easy to use
QJson is fast and reliable. Don’t waste your time writing another JSON parser!
Converting a JSON object to a QVariant requires just three lines of code:
1 // create a JSonDriver instance
2 QJson::Parser parser;
3 bool ok;
4
5 // json is a QString containing the data to convert
6 QVariant result = parser.parse (json, &ok);
It’s also possible to convert QVariant instances to JSON objects:
1 // create a Serializer instance
2 QJson::Serializer serializer;
3 const QByteArray serialized = serializer.serialize( json_object );
It’s possible to serialize QObject instances into JSON and also to initialize a QObject using the values stored inside of a JSON object.
