本文整理了Java中org.vertexium.Vertex.getVertices()方法的一些代码示例，展示了Vertex.getVertices()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。Vertex.getVertices()方法的具体详情如下：
包路径：org.vertexium.Vertex
类名称：Vertex
方法名：getVertices

Vertex.getVertices介绍

[英]Similar to getEdges but gets the vertices on the other side of the edges attached to this vertex that have the given label.
[中]与GetEdge类似，但获取附加到此顶点的边的另一侧具有给定标签的顶点。
