Interface GraphRenderPolicy

public interface GraphRenderPolicy

Handles the rendering of the individual parts of a graph.

Design rationale

This interface separates the core functionality of graph layout algorithms from the exact visual presentation and rendering of graphs. The client implements this interface to specify the exact presentation of graphs. Among other things, this interface allows the client to:

Select shapes, colors, etc... for the presentation of nodes.
Select colors, thickness and style, etc... for the edges.
Hide nodes and edges by simply not rendering them.
Perform scaling and other transformations before rendering the objects.

Note: The methods implementing this interface may freely modify the Rectangle- and BSpline-objects passed to the methods.

Method Summary

void renderEdge(java.lang.Object edge, BSpline spline)
          Renders the edge according to the B-spline curve.

void renderLabel(java.lang.Object label, java.awt.Rectangle box)
          Renders the label to the specified box.

void renderNode(java.lang.Object node, java.awt.Rectangle box)
          Renders the node to the specified box.
