QVariantConstPointer (QVariant variant )
QVariant operator* () const
const QVariant * operator-> () const

详细描述

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 .
