MigrationOperation

                  long[] replicaVersions,
                  Collection<Operation> tasks,
                  int partitionStateVersion)

Method Detail

getMigrationParticipantType

protected InternalMigrationListener.MigrationParticipant getMigrationParticipantType()

run

public void run()
         throws Exception

Specified by:

run in class Operation

Throws:

Exception

getMigrationEvent

protected PartitionMigrationEvent getMigrationEvent()

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

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException

Throws:

IOException

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Throws:

IOException

toString

protected void toString(StringBuilder sb)

Description copied from class: Operation

A template method allows for additional information to be passed into the Operation.toString() method. So an Operation subclass can override this method and add additional debugging content. The default implementation does nothing so one is not forced to provide an empty implementation. It is a good practice always to call the super.toString(stringBuffer) when implementing this method to make sure that the super class can inject content if needed.

Parameters:

sb - the StringBuilder to add the debug info to.

beforeRun

public final void beforeRun()
                     throws Exception

Overrides:

beforeRun in class Operation

Throws:

Exception

getMigrationInfo

public MigrationInfo getMigrationInfo()

getResponse

public Object getResponse()

Overrides:

getResponse in class Operation

validatesTarget

public final boolean validatesTarget()

Overrides:

validatesTarget 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

logError

public void logError(Throwable e)

Description copied from class: Operation

Logs Exception/Error thrown during operation execution. Operation implementations can override this behaviour due to their needs.

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

Overrides:

logError in class Operation

Parameters:

e - Exception/Error thrown during operation execution
