类名称：Graph
方法名：getVertices

Graph.getVertices介绍

[英]Gets all vertices matching the given ids on the graph. The order of the returned vertices is not guaranteed Graph#getVerticesInOrder(Iterable,Authorizations). Vertices are not kept in memory during the iteration.
[中]获取与图上给定ID匹配的所有顶点。返回顶点的顺序不保证图#getVerticesInOrder（Iterable，Authorizations）。迭代期间，顶点不会保留在内存中。
