Method Detail

run

public void run()

Specified by:

run in class Operation

afterRun

public void afterRun()

Overrides:

afterRun in class BasePutOperation

getResponse

public Object getResponse()

Specified by:

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:

Overrides:

shouldBackup in class BasePutOperation

Returns:

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

onWaitExpire

Specified by:

onWaitExpire in interface WaitSupport

Overrides:

onWaitExpire in class BasePutOperation

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException

Overrides:

writeInternal in class KeyBasedMapOperation

Throws:

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Overrides:

readInternal in class KeyBasedMapOperation

Throws:

IOException

toString

public String toString()

Overrides:

toString in class BasePutOperation
