Class KeyValueJob<KeyIn,ValueIn>

java.lang.Object

com.hazelcast.mapreduce.impl.AbstractJob<KeyIn,ValueIn>

com.hazelcast.mapreduce.impl.task.KeyValueJob<KeyIn,ValueIn>

Type Parameters:

KeyIn - type of the key

ValueIn - type of the value

All Implemented Interfaces:

Job<KeyIn,ValueIn>

public class KeyValueJob<KeyIn,ValueIn>
extends AbstractJob<KeyIn,ValueIn>

This class is the internal representation of a map reduce job. It is responsible for requesting the preparation, processing and sets up the future to retrieve the value in a fully reactive way.
