java memory model

We can extend the lock granularity technique to handle this situation, although we must be careful as there are some potential Java Memory Model ( JMM) hazards associated with this approach.

我们可以扩展锁粒度技术以应付这种情形，尽管我们必须很小心，因为有与这种方法有关的一些Java内存模型（Java Memory Model，JMM）危害。

You can override the memory model by setting the LDR_CNTRL environment variable yourself before starting the Java launcher.

您可以覆盖内存模型，方法是在启动Java启动程序之前设置LDR CNTRL环境变量。

Achieving thread-safety without locking is tricky and requires a deep understanding of the details of the Java Memory Model.

要在不使用锁的情况下取得线程安全性需要一定的技巧性，并且需要对Java内存模型（Java Memory Model）的细节有深入的理解。

In the same time, Java Memory Model ( JMM) allows compilers to change the executing order of programs in the optimization progress. This will lead to lots of unexpected errors in multithreaded Java programs.

同时，Java内存模型JMM（Java Memory Model）允许编译器在优化过程中改变程序的执行顺序，这会让多线程Java程序产生许多意想不到的错误。

With locking there are a number of optimizations that are simply not allowed because they would break the specification described by the Java Memory Model.

对于锁来说，由于很多优化行为违反了Java存储模型中描述的规范，所以它们是被禁止的。

Based on the deficiency, this paper analyses Java Memory Model ( JMM), the reason for DCL invalidation and the interior mechanism of "ThreadLocal". The strategy to design the object of class by singleton model is proposed.

针对这些不足，本文结合实例分析了Java内存模型（JMM）、DCL失效原因以及ThreadLocal的内部运行机制，给出了将类的对象设计成Singleton模式的策略。
