Clear QJson Objcts/Arrays
-
Hello on the other screen,
i´m looking for a way to clear QJson Objects/Arrays. My OS is Windows 7.
My situation is, that i´m implementing a statemachine which is doing measurments in each case and the machine is triggered cyclic.
So i can´t use Json Objects/Arrays in this way "QJsonObject myObjct" because it would vanish at the end of every cycle.
I tried to do it by using dynamic allocation, but it feels like the envoironment doesn´t like that.
When i make it like "static QJsonObject myObjct" i guess i would have to clear the Objects/Arrays for the next sequence when all measurements are done and saved to the file.
How do i clear the Json Obcts/Arrays? Especially i´m asking because i´m not sure what happens behind the scenes and what i have to take into consideration when appending Objects to arrays and assining arrays to objects.best regards,
MoeA lovely day for a ̶g̶̶u̶̶i̶̶n̶̶n̶̶e̶̶s̶ DUFF^^

Just assign an empty object/array to your variable:
myObjct = QJsonObject();Or, use
QJsonObject::erase()/QJsonArray::erase()
