Method Details

createAccumulator

public AggInputTransform.AccInputTransform<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 AggInputTransform.AccInputTransform<I,E,J,O,SUBACC> combine(AggInputTransform.AccInputTransform<I,E,J,O,SUBACC> a,
 AggInputTransform.AccInputTransform<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
