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
IgniteFuture<?>	onDiscovery(int type, long topVer, ClusterNode node, Collection<ClusterNode> topSnapshot, @Nullable Map<Long,Collection<ClusterNode>> topHist, @Nullable DiscoverySpiCustomMessage data) Notification for grid node discovery events.
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

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

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.

data - Data for custom event.

Returns:

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