com.hazelcast.cache.BackupAwareEntryProcessor

An invocable function that allows applications to perform compound operations on a {@link javax.cache.Cache.Entry} atomically, according the definedconsistency of a {@link javax.cache.Cache}.

In difference to the normal {@link javax.cache.processor.EntryProcessor}implementations where a backup is done using sending the complete changed resulting object to the backup-partition, implementations of this sub-interface can create an additional {@link javax.cache.processor.EntryProcessor} instances that are sendto the backup-partitions to apply logic which is either different from the owner partition (e.g. not sending emails) or in the simple case similar to the main operations. In the later case {@link #createBackupEntryProcessor()} can also return

this

. @param < K> the type of keys maintained by this cache @param < V> the type of cached values @param < T> the type of the return value @see javax.cache.processor.EntryProcessor @since 3.4
