Class PostPonePartitionProcessing

java.lang.Object

com.hazelcast.spi.Operation

com.hazelcast.mapreduce.impl.operation.ProcessingOperation

com.hazelcast.mapreduce.impl.operation.PostPonePartitionProcessing

All Implemented Interfaces:

DataSerializable, IdentifiedDataSerializable

public class PostPonePartitionProcessing
extends ProcessingOperation

This operation is used to tell the job owner to postpone a mapping phase for the defined partitionId. This can happen if the partitionId might not yet be assigned to any cluster members.

Method Detail

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

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 Operation

Throws:

Exception

See Also:

Operation.call()

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException

Overrides:

writeInternal in class ProcessingOperation

Throws:

IOException

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Overrides:

readInternal in class ProcessingOperation

Throws:

IOException

getFactoryId

public int getFactoryId()

Description copied from interface: IdentifiedDataSerializable

Returns DataSerializableFactory factory ID for this class.

Returns:

factory ID

getId

public int getId()

Description copied from interface: IdentifiedDataSerializable

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

Returns:

type ID
