Class DrillDownOnPositionTransform

org.olap4j.transform.DrillDownOnPositionTransform

All Implemented Interfaces:

MdxQueryTransform

public class DrillDownOnPositionTransform
extends AxisTransform

Drill down on position transform

TODO: transform to be completed, not working for now.

Description: Adds the children of a member at a specific position on an axis. The member to drill is identified from a CellSet with the axis, positionOrdinalInAxis and memberOrdinalInPosition arguments. The drilled member will still be present on the axis, in addition to its children. It is recommended to apply a Hierarchize transform to the same axis of the resulting query, in order to have members in correct hierarchical order.

Example of use: the user clicks on a member in a crosstab axis, in order to see its children in addition to the member itself.

Applicability: this transform is applicable only to members in a query that are drillable, i.e. non-leaf members. The CellSet resulting from the execution of the initial MDX query must also be available.
