Convert QByteArray to std::istream or std::ifstream

[sayan275]

How can I convert a QByteArray to std::istream or std::ifstream? Without saving QByteArray in a filename. I want to create a istream from the QByteArray, on the runtime, without saving a physical file in memory of QByteArray.

I found that there are so many ways to do the opposite thing..ie, istream to QByteArray.

Not really able to make-out how to do the opposite thing.

@sayan275 You could use http://doc.qt.io/qt-5/qbytearray.html#toStdString or http://doc.qt.io/qt-5/qbytearray.html#data-1
