Constructor Detail

CompareAndSetOperation

public CompareAndSetOperation()

CompareAndSetOperation

public CompareAndSetOperation(String name,
                              Data expect,
                              Data update)
Method Detail

run

public void run()
         throws Exception
Specified by:
run in class Operation
Throws:
Exception

getResponse

public Object getResponse()
Overrides:
getResponse in class AtomicReferenceBaseOperation

getId

public int getId()
Description copied from interface: IdentifiedDataSerializable
Returns type identifier for this class. Id should be unique per DataSerializableFactory.

Returns:
type id

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException
Overrides:
writeInternal in class AtomicReferenceBaseOperation
Throws:
IOException

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException
Overrides:
readInternal in class AtomicReferenceBaseOperation
Throws:
IOException

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 AtomicReferenceBackupAwareOperation
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.
