atomically, according to the defined
consistency of a Cache
.
The difference from the normal EntryProcessor
implementations, where a backup is done sending the completely changed resulting
object to the backup-partition, is that implementations of this sub-interface can create
additional EntryProcessor
instances that are sent
to the backup partitions to apply logic which is either different from the owner
partition (e.g. not sending emails) or is the simple case of being similar to the main
operations. In the later case createBackupEntryProcessor()
can also return
this.
EntryProcessor
Modifier and Type | Method and Description |
---|---|
javax.cache.processor.EntryProcessor<K,V,T> |
createBackupEntryProcessor()
Either creates a new, specialized
EntryProcessor
to be executed on the backup-partition, or returns |
javax.cache.processor.EntryProcessor<K,V,T> createBackupEntryProcessor()
EntryProcessor
to be executed on the backup-partition, or returns thisto execute the same processor remotely.
If null is returned, the value is backed up using the normal value backup mechanism, no exception is thrown, and the update is applied as expected.
