Method Details

createAccumulator

public AggOutputTransform.AccOutputTransform<I,E,O,P,SUBACC> createAccumulator()

Specified by:

createAccumulator in interface Aggregator<I,E,O>

Specified by:

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

combine

 AggOutputTransform.AccOutputTransform<I,E,O,P,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,O,P>

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
