Interface DiscoverySpiListener

public interface DiscoverySpiListener

Listener for grid node discovery events. See DiscoverySpi for information on how grid nodes get discovered.

Method Summary

Modifier and Type	Method and Description
default IgniteFuture<?>	onDiscovery(DiscoveryNotification notification) Notification for grid node discovery events.
IgniteFuture<?>	onDiscovery(int type, long topVer, ClusterNode node, Collection<ClusterNode> topSnapshot, Map<Long,Collection<ClusterNode>> topHist, DiscoverySpiCustomMessage data) Deprecated. Use onDiscovery(DiscoveryNotification)
void	onLocalNodeInitialized(ClusterNode locNode) Notification of local node initialization.

Method Detail

onLocalNodeInitialized

void onLocalNodeInitialized(ClusterNode locNode)

Notification of local node initialization. At the time this method is called, it is guaranteed that local node consistent ID is available, but the discovery process is not started yet. This method should not block for a long time since it blocks discovery.

Parameters:

locNode - Initialized local node.

onDiscovery

@Deprecated
IgniteFuture<?> onDiscovery(int type,
                                        long topVer,
                                        ClusterNode node,
                                        Collection<ClusterNode> topSnapshot,
                                        Map<Long,Collection<ClusterNode>> topHist,
                                        DiscoverySpiCustomMessage data)

Deprecated. Use onDiscovery(DiscoveryNotification)

Notification for grid node discovery events.

Parameters:

type - Node discovery event type. See DiscoveryEvent

topVer - Topology version or 0 if configured discovery SPI implementation does not support versioning.

node - Node affected (e.g. newly joined node, left node, failed node or local node).

topSnapshot - Topology snapshot after event has been occurred (e.g. if event is EVT_NODE_JOINED, then joined node will be in snapshot).

topHist - Topology snapshots history, null if first discovery event.

data - Data for custom event, null if not a discovery event.

Returns:

A future that will be completed when notification process has finished.

onDiscovery

default IgniteFuture<?> onDiscovery(DiscoveryNotification notification)

Notification for grid node discovery events.

Parameters:

notification - Discovery notification object.

Returns:

A future that will be completed when notification process has finished.
