Question

我写了一个相当简单的类的文档，但我觉得它不够清楚。我应该改变什么吗？

/**
    Pointer class that wraps resources loaded through the ResourceManager.
    The manager is notified to increase or decrease the reference count of
    a resource, as a ResourcePtr gets copied, created, or deleted.

    If a resource has a reference count of zero, the ResourceManager will
    delete it. The reference count of a resource is the same as the number
    of ResourcePtr objects that reference it.

    \see ResourceManager
                                                                             */

        Default constructor. Creates an empty ResourcePtr that does not
        reference any resource.

    ResourcePtr();
    /**

    ResourcePtr(const ResourcePtr<T>& other);
    /**

您错过了这些评论都是不必要的事实，只会使代码更难以阅读和理解。它们相当于：

  i++; // increment i

这个文件缺少什么吗？
