List of reducer() Examples

Examples of reducer()

com.hazelcast.mapreduce.MappingJob.reducer()
Defines the {@link ReducerFactory} for this task. This method is not idempotent and is callable only one time. Furthercalls result in an {@link IllegalStateException} to be thrown telling you to not change the internal state. @param reducerFactory ReducerFactory to build Reducers @param < ValueOut> type of the reduced value @return instance of this Job with generics changed on usage
org.springframework.batch.core.jsr.step.builder.JsrPartitionStepBuilder.reducer()
@param reducer used to provide a single callback at the beginning and endof a partitioned step. @return this
