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

Graph.configuration介绍

[英]Get the org.apache.commons.configuration.Configuration associated with the construction of this graph. Whatever configuration was passed to GraphFactory#open(org.apache.commons.configuration.Configuration)is what should be returned by this method.
[中]获取组织。阿帕奇。平民配置与此图的构造关联的配置。传递给GraphFactory#open（org.apache.commons.configuration.configuration）的任何配置都是此方法应该返回的。
