TxnSetOperation

public TxnSetOperation(String name,
                       Data dataKey,
                       Data value,

                       long ttl)

Method Detail

shouldWait

public boolean shouldWait()

Specified by:

shouldWait in interface BlockingOperation

Overrides:

shouldWait in class LockAwareOperation

innerBeforeRun

public void innerBeforeRun()
                    throws Exception

Overrides:

innerBeforeRun in class MapOperation

Throws:

Exception

run

public void run()

Description copied from class: Operation

Runs the operation. Either the Operation.run() or Operation.call() method should be implemented; not both. Runs after wait-support, supposed to do actual operation

Overrides:

run in class Operation

See Also:

Operation.call()

getVersion

public long getVersion()

Specified by:

getVersion in interface MapTxnOperation

setVersion

public void setVersion(long version)

Specified by:

setVersion in interface MapTxnOperation

setOwnerUuid

public void setOwnerUuid(String ownerUuid)

Specified by:

setOwnerUuid in interface MapTxnOperation

getResponse

public Object getResponse()

Description copied from class: Operation

Called if and only if Operation.returnsResponse() returned true, shortly after Operation.run() returns.

Overrides:

getResponse in class Operation

shouldNotify

public boolean shouldNotify()

Specified by:

shouldNotify in interface Notifier

shouldUnlockKeyOnBackup

protected boolean shouldUnlockKeyOnBackup()

Overrides:

shouldUnlockKeyOnBackup in class BasePutOperation

onWaitExpire

public void onWaitExpire()

Specified by:

onWaitExpire in interface BlockingOperation

Overrides:

onWaitExpire in class BasePutOperation

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

Overrides:

shouldBackup in class BasePutOperation

Returns:

true if a backup needs to be made, false otherwise.

getNotifiedKey

public WaitNotifyKey getNotifiedKey()

Specified by:

getNotifiedKey in interface Notifier

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException

Overrides:

writeInternal in class KeyBasedMapOperation

Throws:

IOException

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Overrides:

readInternal in class KeyBasedMapOperation

Throws:

IOException

getId

public int getId()

Description copied from interface: IdentifiedDataSerializable

Returns type identifier for this class. It should be unique per DataSerializableFactory.

Specified by:

getId in interface IdentifiedDataSerializable

Returns:

type ID
