Method Detail

run

public void run()

Overrides:

run in class Operation

afterRun

public void afterRun()

Overrides:

afterRun in class BasePutOperation

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

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.

onWaitExpire

public void onWaitExpire()

Specified by:

onWaitExpire in interface BlockingOperation

Overrides:

onWaitExpire in class BasePutOperation

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
