org.aksw.jenax.arq.aggregation.AccStaticMultiplex<B,E,K,U,V>
Type Parameters:
K -
V -
All Implemented Interfaces:
org.aksw.commons.collector.domain.Accumulator<B,E,Map<K,V>>
public class AccStaticMultiplex<B,E,K,U,V> extends Object implements org.aksw.commons.collector.domain.Accumulator<B,E,Map<K,V>>
An ggregator that initialized with a static map<Key, Aggregator<...> Every key in the map is passed to a function that yields the value to be passed as the new binding to the child accumulator. Hence, this accumulator is 'map'-centric as its the map's keys that drive the lookup TODO Clarify relation between AggObject, AggMap and AggStaticMultiplex
