A better QIODevice abstraction

    XMLWordPrintable

    Details

      Description

      QIODevice has several shortcomings:

      • it requires inheritance
      • it buffers/copies data
      • it is designed for synchronous usage
      • error handling is limited

      Separating the producing and consuming of data independent from how the data is processed, would give us a lot more flexibility, allowing piping, implementing a device without inheritance, and not be tied to a synchronous API.
