  +--ostore.inner.TimedHeartbeatRespMsg

All Implemented Interfaces:

QueueElementIF, QuickSerializable

public class TimedHeartbeatRespMsg

extends Object

implements QueueElementIF, QuickSerializable

The response to a timed hearbeat request. Now sent down the dissemination tree, so no longer a TapestryRouteMsg.

Field Summary

SecureHash	aguid The AGUID of the requested heartbeat.
SignedQS	signed_hb This could be any one of a number of things.

Constructor Summary

TimedHeartbeatRespMsg(InputBuffer buffer)

TimedHeartbeatRespMsg(SecureHash aguid, SignedQS signed_hb)

Method Summary

Heartbeat	hb() Extracts the Heartbeat object from the signed_hb member and returns it.
void	serialize(OutputBuffer buffer) Add the object to the buffer.

Field Detail

signed_hb

public SignedQS signed_hb

This could be any one of a number of things. It could be a simple signed Heartbeat, or it could be an UpdateResp, or it could be a LatestHeartbeatResp. Generally, the inner ring will just send whatever certificate it has with the latest timestamp available. Thus the function hb(), below, can be used to extract the actual Heartbeat object from this SignedQS. Note, however, that in order to ensure this is a valid Heartbeat, the signature in the SignedQS should still be verified. See the comments in Heartbeat for information about why this is so screwy.

hb()

aguid

public SecureHash aguid

The AGUID of the requested heartbeat. This field is necessary, since the latest HB the PR may have for a given data object could be an UpdateResp which is a certificate of the currency of several AGUID to VHASH mappings. Thus we provide the AGUID given in the request in order to help pair each response with its corresponding request.
