Class LinearSegmentsDrawer

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

All Implemented Interfaces:

Drawer

public class LinearSegmentsDrawer
extends AbstractDrawer

This class implements the drawing phase of the HierarchicLayouter (i.e., the assignment of nodes' coordinates).

Edges are represented as polyline segments with at most two bends.

Method Detail

assignCoordinates

protected void assignCoordinates(NodeList[] layers,
                                 DataProvider layerID)

Assigns the final coordinates to the objects of the graph such that edges are drawn as polyline segments with at most two bends.

Specified by:

assignCoordinates in class AbstractDrawer

Parameters:

layers - an array of NodeLists each of which contains nodes that belong to the same layer

layerID - the DataProvider that returns the zero-based index of the layer to which each node belongs
