Method Detail

run

public void run()
         throws Exception

Specified by:

run in class Operation

Throws:

Exception

unlock

              throws Exception

Overrides:

afterRun in class AbstractOperation

Throws:

Exception

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.

shouldBackup

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

Specified by:

getId in interface IdentifiedDataSerializable

Returns:

type id
