Example 10 with Cluster

use of com.hazelcast.core.Cluster in project hazelcast by hazelcast.

    String id2 = cluster.addMembershipListener(membershipListener);
    // first we check if the registration id's are different
    assertNotEquals(id1, id2);
    // an now we make sure that if a member joins the cluster, the same interface gets invoked twice.
    HazelcastInstance hz2 = factory.newHazelcastInstance();
