} while( CAS(p->next, NULL, n) != TRUE); //while条件注释:如果没有把结点链在尾指针上,再试 CAS(Q->tail, p, n); //置尾结点 tail = n; } 我们可以看到,程序中的那个 do-while 的 Retry-Loop 中的 CAS 操作:如果 p->next 是 NULL,那么,把新结点 n 加到队尾。如果不成功,则重新再来...

"I watched as car after car drove past her while their drivers averted their eyes. As I came closer my better angels whispered in my ear and I quickly grabbed my wallet and pulled out the little cash I had left. I stopped next to her, rolled down my window, and quickly put it in ...
首先,在这个方法中采用了do-while循环,通过getIntVolatile(var1, var2)获取当前对象指定的字段值,并将其存入var5中作为预期值,这里的getIntVolatile方法可以保证读取的可见性(禁止指令重拍和CPU缓存,这个之前的文章里解释过,不然冗述); 然后,在while中调用了Unsafe类的compareAndSwapInt()方法,进行数据的CAS操作。
The current implementation of the glob filter uses minimatch and is based on includeFilter and excludeFilter options. While it is meant to fit most use cases, some scenarios are not addressed. Use filterHandler option to alter this behavior. The following example demonstrates how to include only...
And not all fears about the future are unfounded. New technologies do result in accidents, they disturb traditional cultures and habits, and they destroy old jobs while creating new ones. But the only way to learn how to make the best use of new technologies and reduce risks is by trial ...
