Q_PROPERTY for every declared member of class. This is convenient because you do not need to create separate structures or classes for serialization of write some code to serialize every class, it's just included to QSerializer.
Download repository
$ git clone https://github.com/smurfomen/QSerializer.gitJust include qserializer.h in your project and enjoy simple serialization. qserializer.h located in src folder.
Set compiler define QS_HAS_JSON or QS_HAS_XML for enabling support for xml or json. Enable both at the same time
is not supported.
A demo project for using QSerializer located in example folder.
To get started, include qserializer.h in your code.
For create serializable member of class and generate propertyes, use macro:
- QS_FIELD
- QS_COLLECTION
- QS_OBJECT
- QS_COLLECTION_OBJECTS
- QS_QT_DICT
- QS_QT_DICT_OBJECTS
- QS_STL_DICT
- QS_STL_DICT_OBJECTS
If you want only declare exists fields - use macro QS_JSON_FIELD, QS_XML_FIELD, QS_JSON_COLLECTION and other (look at qserializer.h)
Inherit from QSerializer, use macro QS_SERIALIZABLE or override metaObject method and declare some serializable fields.
In this case you must use Q_GADGET in your class.
class User : public QSerializer
{
Q_GADGET
QS_SERIALIZABLE
// Create data members to be serialized - you can use this members in code
QS_FIELD(int, age)
QS_COLLECTION(QVector, QString, parents)
};Now you can serialize object of this class to JSON or XML. For example:
User u;
u.age = 20;
u.parents.append("Mary");
u.parents.append("Jeff");
/* case: json value */
QJsonObject jsonUser = u.toJson();
/* case: raw json data */
QByteArray djson = u.toRawJson();
/* case: xml-dom */
QDomNode xmlUser = u.toXml();
/* case: raw xml data */
QByteArray dxml = u.toRawXml();Opposite of the serialization procedure is the deserialization procedure. You can deserialize object from JSON or XML, declared fields will be modified or resets to default for this type values. For example:
...
User u;
/* case: json value */
QJsonObject json;
u.fromJson(json);
/* case: raw json data */
QByteArray rawJson;
u.fromJson(rawJson);
/* case: xml-dom */
QDomNode xml;
u.fromXml(xml);
/* case: raw xml data */
QByteArray rawXml;
u.fromXml(rawXml);| Macro | Description |
|---|---|
| QSERIALIZABLE | Make class or struct is serializable to QSerializer (override QMetaObject method and define Q_GADGET macro) |
| QS_FIELD | Create serializable simple field |
| QS_COLLECTION | Create serializable collection values of primitive types |
| QS_OBJECT | Create serializable inner custom type object |
| QS_COLLECTION_OBJECTS | Create serializable collection of custom type objects |
| QS_QT_DICT | Create serializable dictionary of primitive type values FOR QT DICTIONARY TYPES |
| QS_QT_DICT_OBJECTS | Create serializable dictionary of custom type values FOR QT DICTIONARY TYPES |
| QS_STL_DICT | Create serializable dictionary of primitive type values FOR STL DICTIONARY TYPES |
| QS_STL_DICT_OBJECTS | Create serializable dictionary of custom type values FOR STL DICTIONARY TYPES |
| QS_SERIALIZABLE | Override method metaObject and make class serializable |
