Class MulticastConfig

java.lang.Object
com.hazelcast.config.MulticastConfig

public class MulticastConfig
extends Object
Contains the configuration for the multicast discovery mechanism.

With the multicast discovery mechanism Hazelcast allows Hazelcast members to find each other using multicast. So Hazelcast members do not need to know concrete addresses of members, they just multicast to everyone listening.

It depends on your environment if multicast is possible or allowed; you need to have a look at the TCP/IP cluster: TcpIpConfig.
