Detailed Description
As the generic iterators don't actually instantiate a QVariant on each step, they cannot return a reference to one from operator*(). QVariantRef provides the same functionality as an actual reference to a QVariant would, but is backed by a pointer given as template parameter. The template is implemented for pointers of type QSequentialIterator and QAssociativeIterator.

QVariantRef::QVariantRef(const Pointer *pointer)
Creates a QVariantRef from an pointer.
QVariantRef<Pointer> &QVariantRef::operator=(QVariantRef<Pointer> &&value)
Assigns a new value to the value pointed to by the pointer this QVariantRef refers to.
QVariantRef<Pointer> &QVariantRef::operator=(const QVariantRef<Pointer> &value)
Assigns a new value to the value pointed to by the pointer this QVariantRef refers to.
QVariantRef<Pointer> &QVariantRef::operator=(const QVariant &value)
Assigns a new value to the value pointed to by the pointer this QVariantRef refers to.
QVariant QVariantRef::operator QVariant() const
Resolves the QVariantRef to an actual QVariant.
