The class is not defined to be a general purpose * interface for building this object by anyone other than the * CEC Server process. * * Thread safety: An HdatIoHubFru object is not thread safe. That is, a single * object cannot be shared and used concurrently by multiple * threads at the same time. In fact, an object interface is * used only as a better way to built a flat structure to DMA * to main memory. * * Signal handler usage: This class is not intended to be used in a * signal handler and nothing has been done * to try and make it safe to use * in a signal handler. * * End Class Description */ class HdatIoHubFru : public HdatHdif { public: /** * @brief Construct an HdatIoHubFru object. * * This is the constructor for the HdatIoHubFru object when that I/O HUB * is not currently plugged but has been reserved for concurrent * maintenance. * * If you are constructing this object on the heap by using new, then * you must check the pointer returned from new to see if it is null. * If it is null, new failed to allocate storage and the constructor * was not called.
