y.layout.hierarchic
Class TreeDrawer

java.lang.Object
  y.layout.hierarchic.AbstractDrawer
      y.layout.hierarchic.TreeDrawer

All Implemented Interfaces:

Drawer

public class TreeDrawer
extends AbstractDrawer

This class implements the third phase of the hierarchic layout algorithm for trees. If the input graph is not a tree, an alternative drawer is invoked.

Nested Class Summary

static class

TreeDrawer.HierarchicTreePlacer places nodes in their given layers (does not change the y coordinates) for the TREE layout style of a HierarchicLayouter.

Method Summary

protected void	assignCoordinates(NodeList[] layerLists, DataProvider layerID) Overwrite this method to assign the final coordinates to the objects of he graph.
void	setAlternativeDrawer(Drawer altDrawer) Sets the drawer, which is called when graph is not a tree.
void	setMinimalEdgeDistance(double d) Sets the minimal distance between two edges in the same layer.
void	setMinimalLayerDistance(double d) Sets the minimal distance between two layers.
void	setMinimalMultiEdgeDistance(double d) Sets the minimal distance between two edges sharing source/target in the same layer.
void	setMinimalNodeDistance(double d) Sets the minimal distance between two nodes in the same layer.
