public class DDRepairObjResp

extends DDRouteMsg

DDRepairObjResp is a response sent from a server to a root directory node acknowledging that the server received the DDRepairObjReq and will repair the object.

The root node will know the object is repaired when the number of ptrs increase. The DDRepairObjResp is provided as a clean way for the root node to know an object is being repaired without having to send the DDRepairObjReq to all the remaining servers and without having to wait for the ptrs to increase.
