Guava ValueGraph的简单示例(Simple example of Guava ValueGraph)

 我正在寻找Guava ValueGraph的简单示例。 就像是： 
 
class GraphNode {
  String name;
  String value;
  // Do I need to override equals & hashcode methods here??

}

class GraphUser {
  public ValueGraph<GraphNode,Double> createGraph(){
    ValueGraph<GraphNode,Double> graph = ValueGraphBuilder.directed.build();
    // How do I add the nodes to graph??
    // How do I add the edges to graph?
  }
}
 
 
 
 如何使用自定义对象作为节点创建图形？ 
 
 
 如何向图表添加节点和边缘？ 
 
 
 我是否必须覆盖自定义节点类中的equals和hashCode方法？ 
 
 
 一个简单的例子非常有用。

How do I create graph with custom object as node?
 
 
How do I add nodes & edges to graph?
 
 
Do I have to override the equals & hashCode methods in the custom node class?
 
 
A simple example would be very helpful.
