NSOperation是基于Object-C封装的一套管理与执行线程操作的类。这个类是一个抽象类,通常情况下,我们会使用NSInvocationOperation和NSBlockOperation这两个子类进行多线程的开发,当然我们也可以写继承于NSOperation的类,封装我们自己的操作类。 1、NSOperation抽象类中提供的逻辑方法 操作开始执行 代码语言:javascript 代码运...
If one evaluation modifies a memory location, and the other reads or modifies the same memory location, and if at least one of the evaluations is not an atomic operation, the behavior of the program is undefined (the program has a data race) unless there exists a happens-before relationship...
an operation remains in that queue until it is explicitly canceled or finishes executing its task. Operations within the queue (but not yet executing) are themselves organized according to priority levels and inter-operation object dependencies and are executed accordingly. An ...
C programming language implementation of the isempty() function − bool isempty() { if(front < 0 || front > rear) return true; else return false; } Enqueue Operation Front and rear data pointers are kept in queues. As a result, compared to stack operations, its operations are more co...

To understand how that works first consider a read operation in absence of caching: the head index (read index) needs to be updated and thus that cache line is loaded into the L1 cache in exclusive state. The tail (write index) needs to be read in order to check that the queue is no...
