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...

(0-9). If we had an array of all employees that were randomly ordered, finding employee 111-22-3333 would require, potentially, searching throughallof the elements in the employee array, aO(n) operation. A somewhat better approach would be to sort the employees by their social security ...
(c) Queue discipline, usually FIFO (first-in-first-out), but others are possible, such as last-in-first-out (LIFO) (as the subroutines in a computer program), priority customers (as express check-out lines, giving priority to shorter service times), customers switching lines, etc. Besides...

You can also choose the visibility time that gets added by the ping operation by passing thevisibilityoption: constmsg=awaitqueue.get();constid=awaitqueue.ping(msg.ack,{visibility:10});// this message has had its visibility window extended by 10 seconds instead of// the visibility set by ...
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...
