本文整理了Java中org.eclipse.jgit.lib.Ref.isSymbolic方法的一些代码示例，展示了Ref.isSymbolic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。Ref.isSymbolic方法的具体详情如下：
包路径：org.eclipse.jgit.lib.Ref
类名称：Ref
方法名：isSymbolic

Ref.isSymbolic介绍

[英]Test if this reference is a symbolic reference.

A symbolic reference does not have its own org.eclipse.jgit.lib.ObjectId value, but instead points to another Ref in the same database and always uses that other reference's value as its own.
[中]测试此引用是否为符号引用。
符号引用没有自己的组织。日食jgit。lib。ObjectId值，但指向同一数据库中的另一个引用，并始终使用该另一个引用的值作为自己的值。
