In real life scenarios, many operations on our data are asynchronous. For example, because additional recourses need to get fetched. MST has first class support for asynchronous actions. We will start with a naively implemented async process, and wor…

The NSOperationQueue class regulates the execution of a set of NSOperation objects. After being added to a queue, an operation remains in that queue until it is explicitly canceled or finishes executing its task. Operations within the queue (but not…

一,Execution Tree 执行树是数据流组件(转换和适配器)基于同步关系所建立的逻辑分组,每一个分组都是一个执行树的开始和结束,也可以将执行树理解为一个缓冲区的开始和结束,即缓冲区的整个生命周期. 大家知道,异步转换组件会结束输入缓冲区,创建新的输出缓冲区,所以,执行树的分组实际上通过异步转换组件来划分的,一个异步转换组件意味着上游执行树的结束和下游执行树的开始.当数据流经过异步转换组件,进入一个新的执行树,上一个执行树的缓冲区和相同数据就不再需要了,因为数据已经被传递到一个新的执行树和…
