详细描述

QVariant::Pointer wraps pointed-to value and returns a QVariant::Reference 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 .

`[explicit noexcept(...)]` Pointer:: Pointer ( Pointed && pointed )

构造 QVariant::Pointer from the value pointed to.

注意： This function is noexcept when std::is_nothrow_move_constructible_v<Pointed> is true .

`[explicit noexcept(...)]` Pointer:: Pointer (const Pointed & pointed )

构造 QVariant::Pointer from the value pointed to.

注意： This function is noexcept when std::is_nothrow_copy_constructible_v<Pointed> is true .
