Modifier and Type	Method and Description
void	onBecomingUnknown(Node node, P lastKnownStatus) Notifies when a peer becomes unknown.
void	onUpdate(Node node, P currentStatus) Notifies received remote peers' status updates.

Method Detail

onUpdate

void onUpdate(Node node,
            P currentStatus)

Notifies received remote peers' status updates. This method is called every time an update is received from remote peers, which not necessarily means the status actually changed.

The status of the local peer is not notified.

Parameters:

node - the peer node

currentStatus - peer's current status

onBecomingUnknown

void onBecomingUnknown(Node node,
                     P lastKnownStatus)

Notifies when a peer becomes unknown. See PeerMonitor.getUnknownPeers().

The local peer never becomes unknown. It might be unknown by the time the PeerMonitor is instantiated, but once the initial state is received, it should not be lost.

Parameters:

node - the peer node

lastKnownStatus - peer's last known status
