With the rapid development of computer technology, the structure of software is becoming more and more complex and competition is more and more fierce. In order to ensure the high reliability and
Overview
In a software system, sometimes it is faced with the creation of "a complex object", which is usually composed of sub-objects of each part using a certain algorithm; due to changes in requirements, the various parts of this complex object often face drastic changes, but the algorithms that combine them are relatively stable. How to deal with this change? How can we provide a "encapsulation mechanism" to isolate the changes of "various parts of complex objects", so as to keep the "stable

After all, my memory is limited and many things are often forgotten. Of course, it would be better if it could
