public class ResultSetFlattenerComponent
extends ComponentBase

This class flattens an IPentahoResultSet by looking at a particular column. The flattening is based on a particular column, as we build our consolidated row, we look at the this columns value to create a new consolidated row when it changes. eg) Dec 20, 2005 3432 Dec 20, 2005 235 Dec 20, 2005 8568 Dec 20, 2005 5685 Dec 20, 2005 9873 Dec 29, 2005 24685 Dec 29, 2005 12345 Dec 29, 2005 13151 Dec 29, 2005 12302 Dec 29, 2005 34772 Dec 20, 2005 3432 235 8568 5685 9873 Dec 29, 2005 24685 12345 13151 12302 34772
