Uses of Aggregator in org.aksw.commons.collector.core

Classes in org.aksw.commons.collector.core with type parameters of type Aggregator

Modifier and Type	Class	Description
class	AggFinish<B,I,E,O,C extends Aggregator<B,E,I>>	Convert the output value of an aggregator - this fulfills the role of the 'finisher' in a java8 collector.

Classes in org.aksw.commons.collector.core that implement Aggregator

Modifier and Type	Class	Description
class	AggCounting<I,E>	Aggregator whose accumulator count the number of seen input objects.
class	AggErrorHandler<I,E,O,SUBACC extends Accumulator<I,E,O>,SUBAGG extends ParallelAggregator<I,E,O,SUBACC>>	Wraps another aggregator such that if accumulation fails with an exception an error counter is increased.
class	AggFinish<B,I,E,O,C extends Aggregator<B,E,I>>	Convert the output value of an aggregator - this fulfills the role of the 'finisher' in a java8 collector.
class	AggFromCollector<I,E,O,A>	An aggregator from a collector.
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>>	An aggregator that broadcasts its input to two sub-aggregators that accept the same input.
class	AggInputBroadcastMap<I,E,K,O>	An aggregator that broadcasts its input to multiple sub-aggregators that accept the same input and have the same structure of the output Serves the purpose to perform two independent type safe aggregations on the same input in a single pass.
class	AggInputFilter<I,E,O,SUBACC extends Accumulator<I,E,O>,SUBAGG extends ParallelAggregator<I,E,O,SUBACC>>	Wrap an aggregator such that inputs are passed through a predicate.
class	AggInputFlatMap<I,E,J,O,SUBACC extends Accumulator<J,E,O>,SUBAGG extends ParallelAggregator<J,E,O,SUBACC>>	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.
class	AggInputSplit<I,E,K,J,O,SUBACC extends Accumulator<J,E,O>,SUBAGG extends ParallelAggregator<J,E,O,SUBACC>>	An aggregator that splits the index into a set of keys and forwards the input to the sub-aggregator's accumulator for each key.
class	AggInputTransform<I,E,J,O,SUBACC extends Accumulator<J,E,O>,SUBAGG extends ParallelAggregator<J,E,O,SUBACC>>
class	AggLcaMap<T,E>	Accumulate mappings of least common ancestors Assume a backing tree structure: For each node passed to accumulate assemble a mapping to its LCA with any other lca found so far.
class	AggNatural<I,E,C extends Collection<I>>	Wrapper for a supplier of accumulators with signature I -> Collection<I> This means, that items from the collection can be used as input.
class	AggOutputTransform<I,E,O,P,SUBACC extends Accumulator<I,E,O>,SUBAGG extends ParallelAggregator<I,E,O,SUBACC>>
class	AggReduce<I,E>	Aggregator whose accumulators apply a reduce operation to their value and their input to compute their new value.
