Detailed Description

template<typename Pointed>
class QVariant::ConstPointer< Pointed >

QVariant::ConstPointer is a template class that emulates a const pointer to QVariant.

Since

6.11 \inmodule QtCore

QVariant::ConstPointer wraps pointed-to value and returns a QVariant::ConstReference to it from its operator*(). This makes it suitable as replacement for an actual pointer. We cannot return an actual pointer from generic iterators as the iterators don't hold an actual QVariant.
