Cluster Utilities

Cluster Interface

Hazelcast allows you to register for membership events so you will be notified when members are added or removed. You can also get the set of cluster members.

import com.hazelcast.core.*;

HazelcastInstance hazelcastInstance = Hazelcast.newHazelcastInstance();
Cluster cluster = hazelcastInstance.getCluster();
cluster.addMembershipListener( new MembershipListener() {
  public void memberAdded( MembershipEvent membershipEvent ) {
    System.out.println( "MemberAdded " + membershipEvent );
  }

  public void memberRemoved( MembershipEvent membershipEvent ) {
    System.out.println( "MemberRemoved " + membershipEvent );
  }
} );

Member localMember  = cluster.getLocalMember();
System.out.println ( "my inetAddress= " + localMember.getInetAddress() );

Set setMembers  = cluster.getMembers();
for ( Member member : setMembers ) {
  System.out.println( "isLocalMember " + member.localMember() );
  System.out.println( "member.inetaddress " + member.getInetAddress() );
  System.out.println( "member.port " + member.getPort() );
}
