为给定节点的传出边缘着色 - Jung2 Java Graph Library

Question

晚上好，正如我对其他有关Library Jung2 Java的问题所做的那样，在没有具体文件和时间的情况下，我想请求帮助。

在这种情况下，由于我的代码，我想知道是否有一种颜色从Graph的特定节点传出的所有边缘的颜色，因为它是特定问题的答案。

提前谢谢。

UndirectedGraph<String, String> graphStruct = new UndirectedSparseMultigraph<String, String>();

Hashtable<String, NodeData> nodeCollection = new Hashtable<String, NodeData>();

Hashtable<String, EdgeData> edgeCollection = new Hashtable<String, EdgeData>();

                                   ...
                                   ...
                                   ...

edgeCollection.put(""+edge, new EdgeClass(edge, "Id+"+edge));

                                   ...
                                   ...

vv.getRenderContext().setVertexLabelTransformer(new NodeId(nodeCollection));

JLabel label = new JLabel();

label.setText("Graph");
vv.add(label);

vv.setGraphMouse(inter);
vv.setPreferredSize(new Dimension(1600,1000));
vv.setLocation(500, 500);

vv.setGraphLayout(new CircleLayout(graphStruct));

final JFrame frame = new JFrame();
frame.setTitle("Graph Rappresentation"); 
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().add(vv);
frame.pack();
