Method Detail

andCombine

@Nonnull
public AggregateOperationBuilder.Arity3<T0,T1,T2,A,R> andCombine(@Nullable
                                                                          BiConsumerEx<? super A,? super A> combineFn)

Registers the combine primitive.

The given function must be stateless and cooperative.

andDeduct

@Nonnull
public AggregateOperationBuilder.Arity3<T0,T1,T2,A,R> andDeduct(@Nullable
                                                                         BiConsumerEx<? super A,? super A> deductFn)

Registers the deduct primitive.

The given function must be stateless and cooperative.

andExport

@Nonnull
public <R_NEW> AggregateOperationBuilder.Arity3<T0,T1,T2,A,R_NEW> andExport(@Nonnull
                                                                                     FunctionEx<? super A,? extends R_NEW> exportFn)

The given function must be stateless and cooperative.

andFinish

@Nonnull
public AggregateOperation3<T0,T1,T2,A,R> andFinish(@Nonnull
                                                            FunctionEx<? super A,? extends R> finishFn)

Registers the finish primitive. Constructs and returns an AggregateOperation3 from the current state of the builder.

The given function must be stateless and cooperative.

Throws:

IllegalStateException - if the export primitive was not registered

andExportFinish

@Nonnull
public <R_NEW> AggregateOperation3<T0,T1,T2,A,R_NEW> andExportFinish(@Nonnull
                                                                              FunctionEx<? super A,? extends R_NEW> exportFinishFn)

Registers the supplied function as both the export and finish primitive. Constructs and returns an AggregateOperation3 from the current state of the builder.

The given function must be stateless and cooperative.

Throws:

IllegalStateException - if the export primitive is already registered
