Class AccMultiplexDynamic<B,E,K,V,W,C extends org.aksw.commons.collector.domain.Aggregator<V,E,W>>

java.lang.Object

org.aksw.jenax.arq.aggregation.AccMultiplexDynamic<B,E,K,V,W,C>

Type Parameters:

B -

K -

V -

C -

All Implemented Interfaces:

org.aksw.commons.collector.domain.Accumulator<B,E,Map<K,W>>

public class AccMultiplexDynamic<B,E,K,V,W,C extends org.aksw.commons.collector.domain.Aggregator<V,E,W>>
extends Object
implements org.aksw.commons.collector.domain.Accumulator<B,E,Map<K,W>>

A more general variant of AccMap2 which maps a binding to multiple keys TODO Decide whether to keep only this general version even if it means having to wrap each key as a singleton collection
