QVariant::ConstPointer Class

template <typename Pointed> class QVariant::ConstPointer

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

This class was introduced in Qt 6.11.

Public Functions

ConstPointer(Pointed &&pointed)
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.
