I have just committed into trunk a couple of changes that make easier to serialize a QObject instance to JSON.
This solution relies on the awesome Qt’s property system.
Suppose the declaration of Person class looks like this:
{% codeblock [class definition] [lang:cpp ] %}
class Person : public QObject
{
Q_OBJECT
Q_PROPERTY(QString name READ name WRITE setName)
Q_PROPERTY(int phoneNumber READ phoneNumber WRITE setPhoneNumber)
Q_PROPERTY(Gender gender READ gender WRITE setGender)
Q_PROPERTY(QDate dob READ dob WRITE setDob)
Q_ENUMS(Gender)
public:
Person(QObject* parent = 0);
~Person();
QString name() const;
void setName(const QString& name);
int phoneNumber() const;
void setPhoneNumber(const int phoneNumber);
enum Gender {Male, Female};
void setGender(Gender gender);
Gender gender() const;
QDate dob() const;
void setDob(const QDate& dob);
private:
QString m_name;
int m_phoneNumber;
Gender m_gender;
QDate m_dob;
};
{% endcodeblock %}
The following code will serialize an instance of Person to JSON:
{% codeblock [Serialize to JSON] [lang:cpp ] %}
Person person;
person.setName(“Flavio”);
person.setPhoneNumber(123456);
person.setGender(Person::Male);
person.setDob(QDate(1982, 7, 12));
Serializer serializer;
qDebug() << serializer.serialize( &person;);
{% endcodeblock %}
The generated output will be: {% codeblock [JSON data] [lang:json ] %} { “dob” : “1982-07-12”, “gender” : 0, “name” : “Flavio”, “phoneNumber” : 123456 } {% endcodeblock %}
I hope you will find this new feature useful. I’m also considering to create a similar method inside the Parser class.
As usual suggestions are welcome.
