Management Cluster Utilities Getting Member Events and Member Sets

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.

The following example code does the above: registers for member events, notified when members are added or removed, and gets 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() );
}
