Method Detail

onDiscovery

void onDiscovery(int type,
               long topVer,
               GridNode node,
               Collection<GridNode> topSnapshot,
               @Nullable
               Map<Long,Collection<GridNode>> topHist)

Notification for grid node discovery events.

Parameters:

type - Node discovery event type. See GridDiscoveryEvent

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.
