ReleaseOperation

public ReleaseOperation()

ReleaseOperation

public ReleaseOperation(String name,
                        int permitCount)
Method Detail

run

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

shouldNotify

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

getNotifiedKey

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

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.

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.

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
