本文整理了Java中com.arjuna.ats.txoj.Lock类的一些代码示例，展示了Lock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。Lock类的具体详情如下：
包路径：com.arjuna.ats.txoj.Lock
类名称：Lock

Lock介绍

[英]Instances of this class (or derived user classes) are used when trying to set a lock. The default implementation provides a single-write/multiple-reader policy. However, by overridding the appropriate methods, other, type-specific concurrency control locks can be implemented.
[中]尝试设置锁定时使用此类（或派生用户类）的实例。默认实现提供单写/多读策略。但是，通过重写适当的方法，可以实现其他特定于类型的并发控制锁。

代码示例

interface MajorObjectWrapper{
 public Object getMajorObject();
}

enum Utility implements MajorObjectWrapper {
 VAULT("Gold"),
 //...
 LOCK(new Lock());

 @Override public Object getMajorObject(){ return obj; }

 private Object obj;

 Utility(Object obj){ this.obj=obj };

}

{
 MajorObjectWrapper wrapper=Utility.VAULT;
 System.out.println(wrapper.getMajorObject());
 // You will get: "Gold"! :)
}
