Class ClientSignatureReq

java.lang.Object
  |
  +--ostore.replica.ClientSignatureReq

All Implemented Interfaces:

QueueElementIF

public class ClientSignatureReq

extends Object

implements QueueElementIF

A request sent from the ReplicaStage to the ClientStage, requesting that the latter sign and dispatch a message on behalf of a client.

No explicit response is required. The ReplicaStage can watch for the requested message itself.

Currently this message is used only to request a LatestHeartbeatReqMsg be sent to the inner ring. If/when others are added, we'll have to generalize the code somewhat.
