Class DiscoveryDataBag

java.lang.Object

org.apache.ignite.spi.discovery.DiscoveryDataBag

public class DiscoveryDataBag
extends Object

Provides interface for GridComponent to collect and exchange discovery data both on joining node and on cluster nodes. It only organizes interaction with components and doesn't provide any capabilities of converting collected data into formats eligible for transmitting over media (like marshalling, compressing and so on).
