本文整理了Java中com.google.common.graph.Network.edgesConnecting()方法的一些代码示例，展示了Network.edgesConnecting()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。Network.edgesConnecting()方法的具体详情如下：
包路径：com.google.common.graph.Network
类名称：Network
方法名：edgesConnecting

Network.edgesConnecting介绍

[英]Returns the set of edges that each directly connect endpoints (in the order, if any, specified by endpoints).

The resulting set of edges will be parallel (i.e. have equal #incidentNodes(Object). If this network does not #allowsParallelEdges(), the resulting set will contain at most one edge (equivalent to edgeConnecting(endpoints).asSet()).

If this network is directed, endpoints must be ordered.
[中]返回每个直接连接端点的边集（按端点指定的顺序，如果有）。
生成的边集将是平行的（即具有相等的#意外节点（对象））。如果此网络不#AllowsParallelEdge（），则结果集最多将包含一条边（相当于EdgeConnection（端点））。资产（））。
如果该网络是定向的，则必须对端点进行排序。
