SWIMPingRequestOriginPeer

public protocol SWIMPingRequestOriginPeer : SWIMPingOriginPeer

A SWIM peer which originated a pingRequest and thus can receive either an ack or nack from the intermediary.


                    
                    
                    nack(acknowledging:target:)

“Negative acknowledge” a ping.

This message may ONLY be send in an indirect-ping scenario from the “middle” peer. Meaning, only a peer which received a pingRequest and wants to send the pingRequestOrigin a nack in order for it to be aware that its message did reach this member, even if it never gets an ack through this member, e.g. since the pings target node is actually not reachable anymore.

Declaration

    acknowledging: SWIM.SequenceNumber,
    target: SWIMPeer

`sequenceNumber`	the sequence number of the incoming `pingRequest` that this nack is a response to
