Example 1 with SinkTransform

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

the class PipelineImpl method drainTo.

@Override
public <T> SinkStage drainTo(@Nonnull Sink<T> sink, GeneralStage<?>... stagesToDrain) {
    if (stagesToDrain == null || stagesToDrain.length == 0) {
        throw new IllegalArgumentException("No stages supplied to Pipeline.drainTo()");
    }
    List<Transform> upstream = Arrays.stream(stagesToDrain).map(s -> (AbstractStage) s).map(s -> s.transform).collect(toList());
    int[] ordinalsToAdapt = IntStream.range(0, stagesToDrain.length).filter(i -> ((ComputeStageImplBase) stagesToDrain[i]).fnAdapter == ADAPT_TO_JET_EVENT).toArray();
    SinkImpl sinkImpl = (SinkImpl) sink;
    SinkTransform sinkTransform = new SinkTransform(sinkImpl, upstream, ordinalsToAdapt);
    SinkStageImpl sinkStage = new SinkStageImpl(sinkTransform, this);
    sinkImpl.onAssignToStage();
    connect(upstream, sinkTransform);
    return sinkStage;
}
