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

Ref.getLeaf介绍

[英]Traverse target references until #isSymbolic() is false.

If #isSymbolic() is false, returns this.

If #isSymbolic() is true, this method recursively traverses #getTarget() until #isSymbolic() returns false.

This method is effectively

  1. return isSymbolic() ? getTarget().getLeaf() : this;

[中]遍历目标引用，直到#isSymbolic（）为false。
如果#isSymbolic（）为false，则返回该值。
如果#isSymbolic（）为true，则此方法递归遍历#getTarget（），直到#isSymbolic（）返回false。
这种方法是有效的

  1. return isSymbolic() ? getTarget().getLeaf() : this;
