Constructor Detail

BeforeAwaitOperation

public BeforeAwaitOperation()

BeforeAwaitOperation

public BeforeAwaitOperation(ObjectNamespace namespace,
                    Data key,
                    long threadId,
                    String conditionId)

Method Detail

beforeRun

public void beforeRun()
               throws Exception

Overrides:

beforeRun in class AbstractOperation

Throws:

Exception

run

public void run()
         throws Exception

Specified by:

run in class Operation

Throws:

Exception

shouldNotify

public boolean shouldNotify()

Specified by:

shouldNotify 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 responsible for making the backup.

getNotifiedKey

public WaitNotifyKey getNotifiedKey()

Specified by:

getNotifiedKey in interface Notifier

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

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException

Overrides:

writeInternal in class BaseLockOperation

Throws:

IOException

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Overrides:

readInternal in class BaseLockOperation

Throws:

IOException
