Class RollUpLevelTransform

org.olap4j.transform.AxisTransform

org.olap4j.transform.RollUpLevelTransform

All Implemented Interfaces:

MdxQueryTransform

public class RollUpLevelTransform
extends AxisTransform

Roll-up level transformation

Description: Replaces a member at a specific position on an axis by all the members of its parent's level. The member to roll-up is identified from a CellSet with the axis, positionOrdinalInAxis and memberOrdinalInPosition arguments.

Example of use: the user clicks on a member in a crosstab axis, in order to roll up to the members of the upper level.

Applicability: this transform is applicable only to members in a query that are have a parent. (Note: how would this work in parent-child hierarchies?)
