AcquireOperation

public AcquireOperation()

AcquireOperation

public AcquireOperation(String name,
                        int permitCount,
                        long timeout)

Method Detail

run

public void run()
         throws Exception

Specified by:

run in class Operation

Throws:

Exception

getWaitKey

public WaitNotifyKey getWaitKey()

Specified by:

getWaitKey in interface WaitSupport

shouldWait

public boolean shouldWait()

Specified by:

shouldWait in interface WaitSupport

onWaitExpire

public void onWaitExpire()

Specified by:

onWaitExpire in interface WaitSupport

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
