本文整理了Java中org.sakaiproject.entity.api.Reference类的一些代码示例，展示了Reference类的具体用法。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。Reference类的具体详情如下：
包路径：org.sakaiproject.entity.api.Reference
类名称：Reference

Reference介绍

[英]Reference holds an immutable(?) reference to a Sakai entity.
[中]引用包含一个不可变的（？）对酒井实体的引用。
