java.lang.Object

org.aksw.commons.collector.core.AggInputBroadcast<I,E,O1,O2,SUBACC1,SUBAGG1,SUBACC2,SUBAGG2>

Type Parameters:

I - Input type

O1 - output type of first aggregator

O2 - output type of second aggregator

SUBACC1 - accumulator type of first aggregator

SUBAGG1 - the type of the first aggregator

SUBACC2 - accumulator type of second aggregator

SUBAGG2 - the type of the second aggregator

All Implemented Interfaces:

Serializable, Aggregator<I, E, Map.Entry<O1,O2>>, ParallelAggregator<I, E, Map.Entry<O1,O2>, AggInputBroadcast.AccInputBroadcast<I,E,O1,O2,SUBACC1,SUBACC2>>

public class AggInputBroadcast<I, E, O1, O2, SUBACC1 extends Accumulator<I,E,O1>, SUBAGG1 extends ParallelAggregator<I,E,O1,SUBACC1>, SUBACC2 extends Accumulator<I,E,O2>, SUBAGG2 extends ParallelAggregator<I,E,O2,SUBACC2>>
extends Object
implements ParallelAggregator<I, E, Map.Entry<O1,O2>, AggInputBroadcast.AccInputBroadcast<I,E,O1,O2,SUBACC1,SUBACC2>>, Serializable

An aggregator that broadcasts its input to two sub-aggregators that accept the same input. Serves the purpose to perform two independent type safe aggregations on the same input in a single pass.

Description copied from interface: ParallelAggregator

Combine accumulators. This method is allowed to mutate any of if its arguments, hence accumulators should be considered exhausted after combination.

Specified by:

combine in interface ParallelAggregator<I,E,O1,O2>

Parameters:

a - First participant of combination

b - Second participant of combination

Returns:

Combined accumulator
