com.hazelcast.map.impl.operation

Class EntryOperation

java.lang.Object

com.hazelcast.spi.Operation

com.hazelcast.map.impl.operation.KeyBasedMapOperation

com.hazelcast.map.impl.operation.LockAwareOperation

com.hazelcast.map.impl.operation.EntryOperation

All Implemented Interfaces:

DataSerializable, BackupAwareOperation, MutatingOperation, NamedOperation, PartitionAwareOperation, WaitSupport

public class EntryOperation
extends LockAwareOperation
implements BackupAwareOperation, MutatingOperation

GOTCHA : This operation LOADS missing keys from map-store, in contrast with PartitionWideEntryOperation.

EntryOperation

public EntryOperation(String name,
              Data dataKey,
              EntryProcessor entryProcessor)

Method Detail

innerBeforeRun

public void innerBeforeRun()

Overrides:

innerBeforeRun in class KeyBasedMapOperation

run

public void run()

Specified by:

run in class Operation

afterRun

public void afterRun()
              throws Exception

Overrides:

afterRun in class KeyBasedMapOperation

Throws:

Exception

onWaitExpire

public void onWaitExpire()

Specified by:

onWaitExpire in interface WaitSupport

Specified by:

onWaitExpire in class LockAwareOperation

getResponse

public Object getResponse()

Specified by:

getResponse in class Operation

toString

public String toString()

Overrides:

toString in class Operation

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.

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.

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.

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.

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Overrides:

readInternal in class KeyBasedMapOperation

Throws:

IOException

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException

Overrides:

writeInternal in class KeyBasedMapOperation

Throws:

IOException
