Class CellLevelData

java.lang.Object
  org.miv.pherd.ntree.util.CellLevelData

All Implemented Interfaces:

CellData

public class CellLevelData
extends Object
implements CellData

Cell data item that put maintain the leveling information.

A cell data register is peer cell in an object nammed NTreeLevels so that groups of cells of the same depth are in a set nammed a level. Each time something changes in the graph, the levels are maintained automatically.

Since:

2007
