Constructor Detail

DeleteOperation

public DeleteOperation()

DeleteOperation

public DeleteOperation(String name,
                       Data dataKey,
                       long threadId)

Method Detail

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()

getBackupOperation

public Operation getBackupOperation()

Description copied from interface: BackupAwareOperation

Creates the BackupOperation responsible for making the backup.

Returns:

the created BackupOperation responsible for making the backup.

shouldWait

public boolean shouldWait()

Specified by:

shouldWait in interface BlockingOperation

Overrides:

shouldWait in class AbstractBackupAwareMultiMapOperation

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

Overrides:

shouldBackup in class AbstractBackupAwareMultiMapOperation

Returns:

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

onWaitExpire

public void onWaitExpire()

Specified by:

onWaitExpire in interface BlockingOperation

Overrides:

onWaitExpire in class AbstractBackupAwareMultiMapOperation

getId

public int getId()

Description copied from interface: IdentifiedDataSerializable

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

Returns:

type ID
