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.
