Examples of com.hazelcast.core.EntryListener

com.hazelcast.core.EntryListener
Map Entry listener to get notified when a map entry is added, removed, updated or evicted. @param < K> key of the map entry @param < V> value of the map entry. @see com.hazelcast.core.IMap#addEntryListener(EntryListener,boolean)
