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

Ref介绍

[英]Pairing of a name and the org.eclipse.jgit.lib.ObjectId it currently has.

A ref in Git is (more or less) a variable that holds a single object identifier. The object identifier can be any valid Git object (blob, tree, commit, annotated tag, ...).

The ref name has the attributes of the ref that was asked for as well as the ref it was resolved to for symbolic refs plus the object id it points to and (for tags) the peeled target object id, i.e. the tag resolved recursively until a non-tag object is referenced.
[中]名称和组织的配对。日食jgit。lib。ObjectId目前有。
Git中的ref（或多或少）是一个包含单个对象标识符的变量。对象标识符可以是任何有效的Git对象（blob、tree、commit、带注释的标记等）。
ref name具有请求的ref的属性，以及符号ref解析为的ref加上它指向的对象id和（标记）剥离的目标对象id，即递归解析的标记，直到引用非标记对象。
