Constructor Detail

CountDownOperation

public CountDownOperation()

CountDownOperation

public CountDownOperation(String name)
Method Detail

run

public void run()
         throws Exception
Specified by:
run in class Operation
Throws:
Exception

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.

shouldNotify

public boolean shouldNotify()
Specified by:
shouldNotify in interface Notifier

getNotifiedKey

public WaitNotifyKey getNotifiedKey()
Specified by:
getNotifiedKey in interface Notifier

getFactoryId

public int getFactoryId()
Description copied from interface: IdentifiedDataSerializable
Returns DataSerializableFactory factory id for this class.

Specified by:
getFactoryId in interface IdentifiedDataSerializable
Returns:
factory id

getId

public int getId()
Description copied from interface: IdentifiedDataSerializable
Returns type identifier for this class. Id should be unique per DataSerializableFactory.

Specified by:
getId in interface IdentifiedDataSerializable
Returns:
type id

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.

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.

returnsResponse

public boolean returnsResponse()
Specified by:
returnsResponse in interface RemotePropagatable<Operation>
Overrides:
returnsResponse in class AbstractOperation

getServiceName

public final String getServiceName()
Overrides:
getServiceName in class Operation

waitNotifyKey

protected WaitNotifyKey waitNotifyKey()
