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

Element.value介绍

[英]Get the value of a Property given it's key. The default implementation calls Element#property and then returns the associated value.
[中]获取给定属性键的属性值。默认实现调用元素#属性，然后返回关联的值。
