Constructor Detail

UnlockIfLeaseExpiredOperation

public UnlockIfLeaseExpiredOperation()

UnlockIfLeaseExpiredOperation

public UnlockIfLeaseExpiredOperation(ObjectNamespace namespace,
                                     Data key,
                                     int version)

Method Detail

run

public void run()

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

See Also:

Operation.call()

shouldBackup

public boolean shouldBackup()

This operation runs on both primary and backup If it is running on backup we should not send a backup operation

Specified by:

shouldBackup in interface BackupAwareOperation

Overrides:

shouldBackup in class UnlockOperation

Returns:

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

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

Overrides:

getId in class UnlockOperation

Returns:

type ID

shouldCheckQuorum

public boolean shouldCheckQuorum()

Description copied from interface: QuorumCheckAwareOperation

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

Specified by:

shouldCheckQuorum in interface QuorumCheckAwareOperation
