Class LazyMapEntry

java.lang.Object

com.hazelcast.map.impl.LazyMapEntry

All Implemented Interfaces:

Serializable, Map.Entry

public class LazyMapEntry
extends Object
implements Map.Entry, Serializable

A Map.Entry implementation which serializes/de-serializes key and value objects on demand. It is beneficial when you need to prevent unneeded serialization/de-serialization when creating a Map.Entry. Mainly targeted to supply a lazy entry to EntryProcessor.process(Map.Entry) and EntryBackupProcessor.processBackup(Map.Entry)} methods.

Note that this implementation is not synchronized and is not thread-safe. LazyMapEntry itself is serializable as long as the object representations of both key and value are serializable. After serialization objects are resolved using injected SerializationService. De-serialized LazyMapEntry does contain object representation only Data representations and SerializationService is set to null. In other words: It's as usable just as a regular Map.Entry.
