包路径：org.apache.tinkerpop.gremlin.process.traversal.Traversal
类名称：Traversal
方法名：iterate

Traversal.iterate介绍

[英]Iterate all the Traverser instances in the traversal. What is returned is the empty traversal. It is assumed that what is desired from the computation is are the sideEffects yielded by the traversal.
[中]迭代遍历中的所有遍历器实例。返回的是空遍历。假设计算所需的是遍历产生的副作用。
