org.aksw.commons.collector.core.AggInputFlatMap<I,E,J,O,SUBACC,SUBAGG>

All Implemented Interfaces:

Serializable, Aggregator<I,E,O>, ParallelAggregator<I, E, O, AggInputFlatMap.AccInputFlatMap<I,E,J,O,SUBACC>>

public class AggInputFlatMap<I, E, J, O, SUBACC extends Accumulator<J,E,O>, SUBAGG extends ParallelAggregator<J,E,O,SUBACC>>
extends Object
implements ParallelAggregator<I, E, O, AggInputFlatMap.AccInputFlatMap<I,E,J,O,SUBACC>>, Serializable

Pass collection valued input to an accumulator that accepts only the individual items For example, pass all nodes of a binding to an accumulator for nodes This operation is a variant of input transform, where the transform target is an iterator. Each item of the iterator then passed to the accumulator.

createAccumulator

public AggInputFlatMap.AccInputFlatMap<I,E,J,O,SUBACC> createAccumulator()

Specified by:

createAccumulator in interface Aggregator<I,E,J>

Specified by:

createAccumulator in interface ParallelAggregator<I,E,J,O>

combine

public AggInputFlatMap.AccInputFlatMap<I,E,J,O,SUBACC> combine(AggInputFlatMap.AccInputFlatMap<I,E,J,O,SUBACC> a,
 AggInputFlatMap.AccInputFlatMap<I,E,J,O,SUBACC> b)

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,J,O>

Parameters:

a - First participant of combination

b - Second participant of combination

Returns:

Combined accumulator

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
