All Implemented Interfaces:

QueueElementIF, QuickSerializable

public class JoinTreeResp

extends DTreeResp

Messages dispatched by a DTreeNode responding to JoinTreeReq message. When the message indicates successful admission, it includes the certificates required to verify signatures on objects from the tree, as well as the most recent heartbeat for the tree's data object. These objects let the local machine immediately begin to interact with the tree securely.

Field Detail

signed_resp

protected SignedQS signed_resp

The signed CreateObjectResp containing the certificates required to check signatures on objects sent down the new tree.
