<p></p> <p><b>New page</b></p><div>This operator defines the projected measures. Note: ProjectionOp explicitly defines the selected measures, it does not remove selected measures from the cube but instead removes the non-selected measures. We assume a [[LEAN Data Cube]] (i.e., dataset with observations on the lowest levels only).<br /> <br /> ProjectionOp gets as input an input operator and a List&lt;Node[]&gt; list with a header and measures according to [[Olap4ld_Metadata#getMeasures.28.29]].</div>
