QVariant::ConstPointer Class
template <typename Pointed> class QVariant::ConstPointerQVariant::ConstPointer is a template class that emulates a const pointer to QVariant. More...
This class was introduced in Qt 6.11.
Public Functions

| ConstPointer(const Pointed &pointed) | |
| QVariant::ConstReference<Pointed> | operator*() const |
Detailed Description
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.
Member Function Documentation
[explicit noexcept(...)] ConstPointer::ConstPointer(Pointed &&pointed)
Constructs a QVariant::ConstPointer from the value pointed to.
Note: This function is noexcept when std::is_nothrow_move_constructible_v<Pointed> is true.
[explicit noexcept(...)] ConstPointer::ConstPointer(const Pointed &pointed)
Constructs a QVariant::ConstPointer from the value pointed to.
Note: This function is noexcept when std::is_nothrow_copy_constructible_v<Pointed> is true.
[noexcept(...)] QVariant::ConstReference<Pointed> ConstPointer::operator*() const
Dereferences the QVariant::ConstPointer to a QVariant::ConstReference.
Note: This function is noexcept when std::is_nothrow_copy_constructible_v<Pointed> is true.
