Command mode is the most let me doubt a pattern, I read a lot of code, just feel vaguely grasp its general principle, I think understanding design mode is the most important to grasp the principle of construction, so that the actual programming of their own guidance. Command mode is actually not a very specific, a lot of patterns, it is this flexibility, let a pe

latter's implementation is far more complex than the former, while the articles on this aspect are less. This does not mean that it is unimportant, instead it plays an important role in some applications. For example, in a data acquisition system, when an application sends a command to a device driver to collect data, a worker thread is created to wait for the data collection to complete, and the application itself can continue to do other work. After the device driver completes the data acquis
