Element介绍

[英]An Element is the base class for both vertices and edges. An element has an identifier that must be unique to its inheriting classes (vertex or edges). An element can maintain a collection of key/value properties. Keys are always Strings and values can be any Object. Particular implementations can reduce the space of objects that can be used as values. Typically, objects are Java primitives (e.g. String, long, int, boolean, etc.)
[中]元素是顶点和边的基类。元素的标识符必须对其继承类（顶点或边）唯一。元素可以维护键/值属性的集合。键始终是字符串，值可以是任何对象。特定的实现可以减少可用作值的对象的空间。通常，对象是Java原语（例如String、long、int、boolean等）
