Interface EntryBackupProcessor<K,V>

Type Parameters:

K - Type of key of a Map.Entry

V - Type of value of a Map.Entry

All Superinterfaces:

Serializable

All Known Implementing Classes:

AbstractRegionCacheEntryProcessor, DeleteSessionEntryProcessor, LockEntryProcessor, SessionUpdateEntryProcessor, UnlockEntryProcessor, UpdateEntryProcessor

public interface EntryBackupProcessor<K,V>
extends Serializable

Processes an entry on a backup partition.

Note that there is a possibility which an EntryProcessor can see that a key exists but its backup processor EntryBackupProcessor may not find it at run time due to an unsent backup of a previous operation (e.g. a previous put). In those situations, Hazelcast internally/eventually will sync those owner and backup partitions so you will not lose any data. When coding an EntryBackupProcessor, you should take that case into account, otherwise NullPointerExceptions can be seen since Map.Entry.getValue() may return null.
