Example 1 with GroupTransform

use of com.hazelcast.jet.impl.pipeline.transform.GroupTransform in project hazelcast by hazelcast.

the class GrAggBuilder method buildBatch.

public <A, R, OUT> BatchStage<OUT> buildBatch(@Nonnull AggregateOperation<A, ? extends R> aggrOp, @Nonnull BiFunctionEx<? super K, ? super R, OUT> mapToOutputFn) {
    checkSerializable(mapToOutputFn, "mapToOutputFn");
    List<Transform> upstreamTransforms = toList(upstreamStages, s -> s.transform);
    AbstractTransform transform = new GroupTransform<>(upstreamTransforms, keyFns, aggrOp, mapToOutputFn);
    pipelineImpl.connect(upstreamStages, transform);
    return new BatchStageImpl<>(transform, pipelineImpl);
