Method Detail

afterRun

public void afterRun()

Overrides:

afterRun in class KeyBasedMapOperation

getResponse

public Object getResponse()

Overrides:

getResponse in class AbstractOperation

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.

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.

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.

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.

onWaitExpire

public void onWaitExpire()

Specified by:

onWaitExpire in interface WaitSupport

Specified by:

onWaitExpire in class LockAwareOperation
