本文整理了Java中com.github.rinde.rinsim.geom.Graph类的一些代码示例，展示了Graph类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Graph类的具体详情如下：
包路径：com.github.rinde.rinsim.geom.Graph
类名称：Graph

Graph介绍

[英]Common interface for graphs (V,E). Nodes are represented by Points and connections are represented by Connections. Graphs are directed.
[中]图（V，E）的公共接口。节点由点表示，连接由连接表示。图形是有方向的。
