Method Detail

run

public void run()

Specified by:

run in class Operation

canThisOpGenerateWANEvent

protected boolean canThisOpGenerateWANEvent()

Overrides:

canThisOpGenerateWANEvent in class BasePutOperation

Returns:

true if this operation can generate WAN event, otherwise return false to indicate WAN event generation is not allowed for this operation

getResponse

public Object getResponse()

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.

afterRun

public void afterRun()

Overrides:

afterRun in class BasePutOperation

getBackupOperation

public Operation getBackupOperation()

Description copied from interface: BackupAwareOperation

Creates the BackupOperation responsible for making the backup.

Specified by:

getBackupOperation in interface BackupAwareOperation

Overrides:

getBackupOperation in class BasePutOperation

Returns:

the created BackupOperation responsible for making the backup.

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException

Overrides:

writeInternal in class MutatingKeyBasedMapOperation

Throws:

IOException

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Overrides:

readInternal in class MutatingKeyBasedMapOperation

Throws:

IOException

getId

public int getId()

Description copied from interface: IdentifiedDataSerializable

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

Returns:

type ID
