Class GetResultOperationFactory

java.lang.Object

com.hazelcast.mapreduce.impl.operation.GetResultOperationFactory

All Implemented Interfaces:

DataSerializable, IdentifiedDataSerializable, OperationFactory

public class GetResultOperationFactory
extends Object
implements OperationFactory

This class is used to create GetResultOperation instances. In difference to other implementations of OperationFactory this class is never ever serialized and the DataSerializable methods readData(com.hazelcast.nio.ObjectDataInput) and writeData(com.hazelcast.nio.ObjectDataOutput) throw UnsupportedOperationExceptions.

Method Detail

createOperation

public Operation createOperation()

Description copied from interface: OperationFactory

Creates the operation.

Specified by:

createOperation in interface OperationFactory

Returns:

the created operation.

writeData

public void writeData(ObjectDataOutput out)
               throws IOException

Description copied from interface: DataSerializable

Writes object fields to output stream

Specified by:

writeData in interface DataSerializable

Parameters:

out - output

Throws:

IOException - if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.

readData

public void readData(ObjectDataInput in)
              throws IOException

Description copied from interface: DataSerializable

Reads fields from the input stream

Specified by:

readData in interface DataSerializable

Parameters:

in - input

Throws:

IOException - if an I/O error occurs. In particular, an IOException may be thrown if the input stream has been closed.

getFactoryId

public int getFactoryId()

Description copied from interface: IdentifiedDataSerializable

Returns DataSerializableFactory factory ID for this class.

Specified by:

getFactoryId in interface IdentifiedDataSerializable

Returns:

factory ID

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
