JUNG2 - 如何设置自定义egde颜色/厚变压器

Question

在我的应用程序中,我想设置每个egde具有不同的风格.它可以是边缘颜色或边缘厚度.我已经读过JUNG的变形金刚,但我没有发现任何有用的东西.

您知道如何将特定颜色或线条粗细设置为特定边缘吗？它可以是某种具有setWidth()或setColour()等方法的Transformer或类.示例会很好;)

Answer 1

谢谢,这是工作示例:

private Transformer<String, Paint> edgePaint = new Transformer<String, Paint>() {
    public Paint transform(String s) {
        return Color.RED;
    }
};

private Transformer<String, Stroke> edgeStroke = new Transformer<String, Stroke>() {
    float dash[] = { 10.0f };
    public Stroke transform(String s) {
        return new BasicStroke(1.0f, BasicStroke.CAP_BUTT,
                BasicStroke.JOIN_MITER, 10.0f, dash, 0.0f);
    }
};

(...)

vv.getRenderContext().setEdgeDrawPaintTransformer(edgePaint);
vv.getRenderContext().setEdgeStrokeTransformer(edgeStroke);
