Project Setup

Open the IDE of your choice and create a new maven project. Add the following dependencies to your pom file:

Now you need to create three new classes:

First, create a new class MyStreamController as follows:

import org.streampipes.model.SpDataStream;
import org.streampipes.model.graph.DataSourceDescription;
import org.streampipes.sources.AbstractAlreadyExistingStream;

public class MyStreamController extends AbstractAlreadyExistingStream {

  @Override
  public SpDataStream declareModel(DataSourceDescription sep) {

  }
}

Next, create a new class MyStreamSource as follows:

import org.streampipes.container.declarer.EventStreamDeclarer;
import org.streampipes.container.declarer.SemanticEventProducerDeclarer;
import org.streampipes.model.graph.DataSourceDescription;

import java.util.List;

public class MyStreamSource implements SemanticEventProducerDeclarer {

    @Override
    public DataSourceDescription declareModel() {
      return null;
    }

    @Override
    public List<EventStreamDeclarer> getEventStreams() {
        return null;
    }
}
