QVariantConstPointer (QVariant variant ) | |
QVariant | operator* () const |
const QVariant * | operator-> () const |
QVariantConstPointer wraps a QVariant and returns it from its operator*(). This makes it suitable as replacement for an actual const pointer. We cannot return an actual const pointer from generic iterators as the iterators don't hold an actual QVariant .
