Interface DrillExpandPosition

All Superinterfaces:

Extension

All Known Implementing Classes:

DrillExpandPositionExt, TestDrillExpandPosition

public interface DrillExpandPosition
extends Extension

allows to expand / collapse members on an axis. If a member is expanded, the member itself plus its children are displayed.

Example: if you expand "Europe" you may see "Germany", "France" etc. If you collapse "Europe" the countries will not be shown.

If multiple Hierarchies are shown on a single axis, only one position is expanded. For example

 -----+-------
 2001 | Europe
 -----+-------
 2002 | Europe
 -----+-------
 2003 | Europe
 -----+-------
 

clicking on Europe in 2002 will give

 -----+-------
 2001 | Europe
 -----+-------
 2002 | Europe
      |   Germany
      |   France
 -----+-------
 2003 | Europe
 -----+-------
