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

shouldBackup in class BasePutOperation
Returns:
true if a backup needs to be made, false otherwise.

onWaitExpire

public void 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:
IOException

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException
Overrides:
readInternal in class KeyBasedMapOperation
Throws:
IOException

toString

public String toString()
Overrides:
toString in class BasePutOperation
