Method Detail

beforeRun

public void beforeRun()
               throws Exception

Description copied from class: Operation

The beforeRun is called before either the Operation.run() or the Operation.call() method is called. runs before wait-support

Overrides:

beforeRun in class Operation

Throws:

Exception

run

public void run()
         throws Exception

Description copied from class: Operation

Runs the operation. Either the Operation.run() or Operation.call() method should be implemented; not both. Runs after wait-support, supposed to do actual operation

Overrides:

run in class Operation

Throws:

Exception

See Also:

Operation.call()

afterRun

public void afterRun()
              throws Exception

Description copied from class: Operation

Is executed called after Operation.run() or Operation.call() method completes normally and the operation is not blocked, see CallStatus.WAIT. Runs after backups, before wait-notify.

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.

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.

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
