Method Detail

run

public void run()
         throws Exception
Specified by:
run in class Operation
Throws:
Exception

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.

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

getBackupOperation

public Operation getBackupOperation()
Description copied from interface: BackupAwareOperation
Creates the BackupOperation responsible for making the backup.

Returns:
the created BackupOperation.

getId

public int getId()
Description copied from interface: IdentifiedDataSerializable
Returns type identifier for this class. Id should be unique per DataSerializableFactory.

Returns:
type id

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException
Overrides:
writeInternal in class AbstractMutatingCacheOperation

                     throws IOException
Overrides:
readInternal in class AbstractMutatingCacheOperation
Throws:
IOException

beforeRun

public final void beforeRun()
                     throws Exception
Overrides:
beforeRun in class AbstractOperation
Throws:
Exception

returnsResponse

public boolean returnsResponse()
Specified by:
returnsResponse in interface RemotePropagatable<Operation>
Overrides:
returnsResponse in class AbstractOperation

getResponse

Overrides:
getResponse in class AbstractOperation

onException

public ExceptionAction onException(Throwable throwable)
Overrides:
onException in class Operation

getFactoryId

public int getFactoryId()
Description copied from interface: IdentifiedDataSerializable
Returns DataSerializableFactory factory id for this class.

Specified by:
getFactoryId in interface IdentifiedDataSerializable
Returns:
factory id

getSyncBackupCount
