Example 21 with RingbufferConfig

use of com.hazelcast.config.RingbufferConfig in project hazelcast by hazelcast.

the class RingbufferAbstractTest method add_overwritingOldData.

 * the ring a few times). At the end we expect to see the latest items; everything
 * that is overwritten should not be shown anymore.
