QtConcurrent::mappedReduced

[wookoon]

QStringList PaltUnit::dayMap(QStringList s)
{
......
}

void PaltUnit:upReduce(QStringList &res,QStringList s)
{
......
}

QStringList PaltUnit::solutionPick()
{
QVector<QStringList> vec;

vec = divStockData(DIVIDEDAYS);

QFuture<QStringList> res = QtConcurrent::mappedReduced<QStringList>(vec, dayMap, upReduce);

return res;
}


the buildissues will show : argument of type 'QStringList(PaltUnit::*)(QStringList)' does not match 'QStringList(PaltUnit::*)(QStringList)' ï¼›
QStringList(PaltUnit::*)(QStringList) is not a class,struct, or union type

If I made "dayMap" and "upReduce" to be globe function, then will build pass. Why..?

So If I want made "dayMap" and "upReduce" still be the member functions of the PaltUnit, what should I do?

There are numerous problems with your current call.

One thing would be to make them static.

But in the current for your code makes completely no sense, you might want to use blockingMappedReduced() instead.
