| QVariantRef<Pointer> | operator*() const |
| Pointer | operator->() const |
详细说明
QVariantConstPointer 封装指针，并从其 operator*() 返回 。这使它适合替代实际指针。我们不能从泛型迭代器中返回实际指针，因为迭代器并不持有实际的 。QVariantRef QVariant
成员函数文档
[explicit] QVariantPointer::QVariantPointer(const Pointer *pointer)
从给定的pointer 中构造一个 QVariantPointer。
QVariantRef<Pointer> QVariantPointer::operator*() const
取消引用QVariantPointer 到QVariantRef 。
Pointer QVariantPointer::operator->() const
取消引用并返回指针。预计指针也会实现 operator->()。
