Method Summary

Modifier and Type	Method and Description
AggregateOperationBuilder.Arity3<T0,T1,T2,A>	andCombine(DistributedBiConsumer<? super A,? super A> combineFn) Registers the combine primitive.
AggregateOperationBuilder.Arity3<T0,T1,T2,A>	andDeduct(DistributedBiConsumer<? super A,? super A> deductFn) Registers the deduct primitive.
<R> AggregateOperation3<T0,T1,T2,A,R>	andFinish(DistributedFunction<? super A,R> finishFn) Constructs and returns an AggregateOperation3 from the current state of the builder and the supplied finish primitive.
AggregateOperation3<T0,T1,T2,A,A>	andIdentityFinish() Constructs and returns an AggregateOperation3 from the current state of the builder, with the identity function as the finish primitive.
