MultipleEntryOperation

public MultipleEntryOperation(String name,
                      Set<Data> keys,
                      EntryProcessor entryProcessor)

Method Detail

innerBeforeRun

public void innerBeforeRun()
                    throws Exception

Overrides:

innerBeforeRun in class MapOperation

Throws:

Exception

run

public void run()
         throws Exception

Specified by:

run in class Operation

Throws:

Exception

getResponse

public Object getResponse()

Overrides:

getResponse in class Operation

shouldBackup

public boolean shouldBackup()

Description copied from interface: BackupAwareOperation

Checks if a backup needs to be made.

If a call has not made any change, e.g. an AtomicLong increment with 0, no backup needs to be made.

Specified by:

shouldBackup in interface BackupAwareOperation

Returns:

true if a backup needs to be made, false otherwise.

getSyncBackupCount

public int getSyncBackupCount()

Description copied from interface: BackupAwareOperation

The synchronous backup count. If no backups need to be made, 0 is returned.

Specified by:

getSyncBackupCount in interface BackupAwareOperation

Returns:

the synchronous backup count.

getAsyncBackupCount

public int getAsyncBackupCount()

Description copied from interface: BackupAwareOperation

The asynchronous backup count. If no asynchronous backups need to be made, 0 is returned.

Specified by:

getAsyncBackupCount in interface BackupAwareOperation

Returns:

the asynchronous backup count.

getBackupOperation

public Operation getBackupOperation()

Description copied from interface: BackupAwareOperation

Creates the BackupOperation responsible for making the backup.

Specified by:

getBackupOperation in interface BackupAwareOperation

Returns:

the created BackupOperation responsible for making the backup.

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Overrides:

readInternal in class AbstractNamedOperation

Throws:

IOException

writeInternal

                      throws IOException

Overrides:

writeInternal in class AbstractNamedOperation

Throws:

IOException
