B) Design principles. Many people have listed seven principles, such as single duty principle, opening and closing principle, Richter substitution principle, dependence inversion principle, interface isolation principle, composite reuse principle and Dimit principle. LSP, I elevated it to one of the three cornerstones of the object-oriented paradigm; Single responsibility and interface isolation are mainly used as the principle of responsibility division in object-oriented analysis/OOA, which you can not pay much attention to at this time. Relying on the inversion principle, I throw it away as garbage, because the opening and closing principle or directly "relying on abstract type principle" already contains the essence of relying on the inversion principle, while the dross of relying on the inversion principle is inherited by IoC. Of course, the pullback, I emphasize very much. Therefore, you need to master the abstract dependency principle (OCP), one-way dependency principle (including the learning of callbacks) and the minimum dependency principle (composite reuse principle, Dimit rule).

FlyWeightFactory is responsible for creating and managing meta-units. When a client requests, the factory needs to check whether there are eligible objects in the current object pool. If so, it returns the existing object. If not, it creates a new object. FlyWeight is a superclass. When it comes to shared pools, It is easy to think of JDBC connection pooling in Java, Considering the characteristics of each connection, It is not difficult for us to sum up: Applies to several objects that are shared, They have some common attributes, Take the database connection pool as an example, url, driverClassName, username, password and dbname, these attributes are the same for each connection, so it is suitable to use the meta-sharing mode to process, build a factory class, take the above similar attributes as internal data and the others as external data, and pass them in as parameters when calling methods, thus saving space and reducing the number of instances.
