Example 6 with Partition

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

the class HazelcastTestSupport method generateKeyOwnedBy.

     *                         set to {@code false} which means generated key will not be owned by the given instance.
     * @return generated string.
