                                long timestamp)

Parameters:

reqId - State change request ID.

initiatingNodeId - Node initiated state change.

storedCfgs - Configurations read from persistent store.

activate - New cluster state.

Method Detail

storedCacheConfigurations

@Nullable
public List<StoredCacheData> storedCacheConfigurations()

Returns:

Configurations read from persistent store..

exchangeActions

@Nullable
public ExchangeActions exchangeActions()

Returns:

stopProcess

public boolean stopProcess()

See DiscoverySpiCustomMessage.stopProcess().

Specified by:

stopProcess in interface DiscoveryCustomMessage
