Method Detail

run

public void run()
         throws Exception

Specified by:

run in class Operation

Throws:

Exception

afterRun

public void afterRun()
              throws Exception

Overrides:

afterRun 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.

Specified by:

shouldBackup in interface BackupAwareOperation

Returns:

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

getResponse

public Object getResponse()

Overrides:

getResponse in class Operation

getSyncBackupCount

public int getSyncBackupCount()

Description copied from interface: BackupAwareOperation

The synchronous backup count. If no backups need to be made, 0 is returned.

Specified by:

getSyncBackupCount in interface BackupAwareOperation

Returns:

the synchronous backup count.

getAsyncBackupCount

public int getAsyncBackupCount()

Description copied from interface: BackupAwareOperation

The asynchronous backup count. If no asynchronous backups need to be made, 0 is returned.

Specified by:

getAsyncBackupCount in interface BackupAwareOperation

Returns:

the asynchronous backup count.

getBackupOperation

public Operation getBackupOperation()

Description copied from interface: BackupAwareOperation

Creates the BackupOperation responsible for making the backup.

Specified by:

getBackupOperation in interface BackupAwareOperation

Returns:

the created BackupOperation responsible for making the backup.

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException

Overrides:

writeInternal in class AbstractNamedOperation

Throws:

IOException

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Overrides:

readInternal in class AbstractNamedOperation

Throws:

IOException

toString

protected void toString(StringBuilder sb)

Description copied from class: Operation

A template method allows for additional information to be passed into the Operation.toString() method. So an Operation subclass can override this method and add additional debugging content. The default implementation does nothing so one is not forced to provide an empty implementation. It is a good practice always to call the super.toString(stringBuffer) when implementing this method to make sure that the super class can inject content if needed.

Overrides:

toString in class AbstractNamedOperation

Parameters:

sb - the StringBuilder to add the debug info to.

getId

public int getId()

Description copied from interface: IdentifiedDataSerializable

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

Specified by:

getId in interface IdentifiedDataSerializable

Returns:

type ID
