If your question is what data types QDataStream supports by default.
And you can always use QDataStream for your customized data types too.
thanks for your answer.But it seems that there are some problems of my description.What I want to achieve is something like data analysis.This is the data analysis of my test source.
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
QSize s(100 , 100);
QString str = "hello world";
QList<QGenericArgument> param;
param<<Q_ARG(QSize , s)<<Q_ARG(QString , str);
netWorkRemoteCall("netwrok" , "sendData" , param);
}
void MainWindow::netWorkRemoteCall(QString className, QString methodName, QList<QGenericArgument> param)
{
QByteArray data;
QStringList typeNames;
QDataStream stream(&data , QIODevice::WriteOnly);
stream<<className<<methodName;
for(int q = 0 ; q < param.size() ; q++)
{
typeNames<<param.at(q).name();
}
stream<<typeNames;
for(int i = 0 ; i < param.size() ; i++)
{
//stream<<param.at(i).name();
if(param.at(i).name() == "QString")
{
QString str = *(QString *)param.at(i).data();
stream<<str;
}
else if(param.at(i).name() == "QSize")
{
QSize size = *(QSize*)param.at(i).data();
stream<<size;
}
}
qDebug()<<data.size();
dataAnalysis(data);
}
void MainWindow::dataAnalysis(QByteArray data)
{
QByteArray datas = data;
qDebug()<<datas.size();
QDataStream stream(datas);
QString className;
QString methodName;
QStringList typeNames;
stream>>className>>methodName>>typeNames;
//qDebug()<<className<<methodName<<" "<<className.size() //+methodName.size();
for(int i = 0 ; i < typeNames.size() ; i++)
{
qDebug()<<typeNames.at(i);
if(typeNames.at(i) == "QString")
{
QString s;
stream>>s;
qDebug()<<s;
}
else if(typeNames.at(i) == "QSize")
{
QSize s;
stream>>s;
qDebug()<<s;
}
}
}
and I want to parse is the data like QVector<QStringList> , QPoint , QHash,QMap.I don't konw whether QDataStram support them.......
