com.hazelcast.internal.partition.operation

Class FinalizeMigrationOperation

java.lang.Object

com.hazelcast.spi.Operation

com.hazelcast.internal.partition.operation.FinalizeMigrationOperation

All Implemented Interfaces:

MigrationCycleOperation, DataSerializable, IdentifiedDataSerializable, AllowedDuringPassiveState, PartitionAwareOperation, UrgentSystemOperation

public final class FinalizeMigrationOperation
extends Operation
implements PartitionAwareOperation, MigrationCycleOperation

Invoked locally on the source or destination of the migration to finalize the migration. This will notify the MigrationAwareServices that the migration finished, updates the replica versions, clears the migration flag and notifies the node engine when successful. There might be ongoing concurrent finalization operations for different partitions.

Constructor Detail

FinalizeMigrationOperation

public FinalizeMigrationOperation()

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

FinalizeMigrationOperation

public FinalizeMigrationOperation(MigrationInfo migrationInfo,
                                  MigrationEndpoint endpoint,
                                  boolean success)

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 Operation

See Also:

Operation.call()

returnsResponse

public boolean returnsResponse()

Description copied from class: Operation

Method is intended to be subclassed. If it returns true, Operation.getResponse() will be called right after Operation.run() method. If it returns false, Operation.sendResponse(Object) must be called later to finish the operation.

In other words, true is for synchronous operation and false is for asynchronous one.

Default implementation is synchronous operation (true).

Overrides:

returnsResponse in class Operation

validatesTarget

public boolean validatesTarget()

Overrides:

validatesTarget in class Operation

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Overrides:

readInternal in class Operation

Throws:

IOException

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException

Overrides:

writeInternal in class Operation

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

Returns:

type ID

getFactoryId

public final int getFactoryId()

Description copied from interface: IdentifiedDataSerializable

Returns DataSerializableFactory factory ID for this class.

Specified by:

getFactoryId in interface IdentifiedDataSerializable

Returns:

factory ID
