Class AddAllOperation

java.lang.Object

com.hazelcast.spi.Operation

com.hazelcast.ringbuffer.impl.operations.AbstractRingBufferOperation

com.hazelcast.ringbuffer.impl.operations.AddAllOperation

All Implemented Interfaces:

DataSerializable, IdentifiedDataSerializable, BackupAwareOperation, MutatingOperation, NamedOperation, Notifier, PartitionAwareOperation, ServiceNamespaceAware

public class AddAllOperation
extends AbstractRingBufferOperation
implements Notifier, BackupAwareOperation, MutatingOperation

Adds a batch of items to the ring buffer. The master node will add the items into the ring buffer, generating sequence IDs. The backup operation will put the items under the generated sequence IDs that the master generated. This is to avoid differences in ring buffer data structures.

AddAllOperation

public AddAllOperation(String name,
                       Data[] items,

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()

getResponse

public Object getResponse()

Description copied from class: Operation

Called if and only if Operation.returnsResponse() returned true, shortly after Operation.run() returns.

Overrides:

getResponse in class Operation

shouldNotify

public boolean shouldNotify()

Specified by:

shouldNotify in interface Notifier

getNotifiedKey

public WaitNotifyKey getNotifiedKey()

Specified by:

getNotifiedKey in interface Notifier

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.

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.

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

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException

Overrides:

writeInternal in class AbstractRingBufferOperation

Throws:

IOException

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Overrides:

readInternal in class AbstractRingBufferOperation

Throws:

IOException
