Class PromotionCommitOperation

java.lang.Object

com.hazelcast.spi.Operation

com.hazelcast.internal.partition.operation.PromotionCommitOperation

All Implemented Interfaces:

MigrationCycleOperation, DataSerializable, IdentifiedDataSerializable, AllowedDuringPassiveState, UrgentSystemOperation

public class PromotionCommitOperation
extends Operation
implements MigrationCycleOperation

Used for committing a promotion on destination. Sent by the master to update the partition table on destination and commit the promotion. The promotion is executed in two stages which are denoted by the beforeStateCompleted property. First it invokes BeforePromotionOperations for every promoted partition. After all operations return it will reschedule itself and finalize the promotions by sending FinalizePromotionOperation for every promotion.

Method Detail

beforeRun

public void beforeRun()
               throws Exception

Overrides:

beforeRun in class Operation

Throws:

Exception

run

public void run()

Overrides:

run in class Operation

afterRun

public void afterRun()
              throws Exception

Overrides:

afterRun in class Operation

Throws:

Exception

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

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

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

getServiceName

public String getServiceName()

Overrides:

getServiceName in class Operation

onInvocationException

public ExceptionAction onInvocationException(Throwable throwable)

Description copied from class: Operation

Called when an Exception/Error is thrown during an invocation. Invocation process will continue, retry or fail according to returned ExceptionAction result.

This method is called on caller side of the invocation.

Overrides:

onInvocationException in class Operation

Parameters:

throwable - Exception/Error thrown during invocation

Returns:

ExceptionAction

onExecutionFailure

public void onExecutionFailure(Throwable e)

Description copied from class: Operation

Called when an Exception/Error is thrown during operation execution.

By default this method does nothing. Operation implementations can override this behaviour due to their needs.

This method is called on node & thread that's executing the operation.

Overrides:

onExecutionFailure in class Operation

Parameters:

e - Exception/Error thrown during operation execution

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

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
