	QVariantPointer (const Pointer * pointer )
QVariantRef<Pointer>	operator* () const
Pointer	operator-> () const

詳細描述

QVariantConstPointer wraps a pointer and returns QVariantRef 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]` QVariantPointer:: QVariantPointer (const Pointer * pointer )

構造 QVariantPointer 從給定 pointer .

QVariantRef < Pointer > QVariantPointer:: operator* () const

解引用 QVariantPointer 到 QVariantRef .

Pointer QVariantPointer:: operator-> () const

解引用並返迴指針。還期望指針實現操作符->()。
