本文整理了Java中com.tinkerpop.blueprints.Graph.getEdges()方法的一些代码示例，展示了Graph.getEdges()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.getEdges()方法的具体详情如下：
包路径：com.tinkerpop.blueprints.Graph
类名称：Graph
方法名：getEdges

Graph.getEdges介绍

[英]Return an iterable to all the edges in the graph. If this is not possible for the implementation, then an UnsupportedOperationException can be thrown.
[中]将iterable返回到图形中的所有边。如果这对于实现是不可能的，那么可以抛出UnsupportedOperationException。
