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.

writeInternal

                     throws IOException

Overrides:

readInternal in class AbstractMutatingCacheOperation

Throws:

IOException

getId

public int getId()

Description copied from interface: IdentifiedDataSerializable

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

Returns:

type id

beforeRun

public final void beforeRun()
                     throws Exception

Overrides:

beforeRun in class AbstractOperation

Throws:

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

public final int getSyncBackupCount()

getAsyncBackupCount
