      • processRow

        public boolean processRow()
                   throws HopException
        Process a single row. In our case, we send one row of data to a piece of pipeline. In the pipeline, we look up the MappingInput transform to send our rows to it. As a consequence, for the time being, there can only be one MappingInput and one MappingOutput transform in the PipelineExecutor.
