Constructor Detail

LocalLockCleanupOperation

public LocalLockCleanupOperation()

This constructor should not be used to obtain an instance of this class; it exists to fulfill IdentifiedDataSerializable coding conventions.

LocalLockCleanupOperation

public LocalLockCleanupOperation(ObjectNamespace namespace,
                                 Data key,
                                 UUID uuid)

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 UnlockOperation

Throws:

Exception

See Also:

Operation.call()

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 UnlockOperation

Returns:

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

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException

Overrides:

writeInternal in class UnlockOperation

Throws:

IOException

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Overrides:

readInternal in class UnlockOperation

Throws:

IOException

getClassId

public int getClassId()

Description copied from interface: IdentifiedDataSerializable

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

Specified by:

getClassId in interface IdentifiedDataSerializable

Overrides:

getClassId in class UnlockOperation

Returns:

type ID

shouldCheckSplitBrainProtection

public boolean shouldCheckSplitBrainProtection()

Description copied from interface: SplitBrainProtectionCheckAwareOperation

Returns true if the split brain protection check should be performed. Operations which require a split brain protection check may get rejected if there are not enough members in the cluster.

Specified by:

shouldCheckSplitBrainProtection in interface SplitBrainProtectionCheckAwareOperation
