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.
From the above command class code, we can see that any operation has an execute method to perform the operation. The above code uses traditional object-oriented programming to implement the command mode. The procedural request call of the command mode is encapsulated in the execute method of the command object. Have we found the above writing code a little cumbersome? We can do this using the callback functions in javascript, In object-oriented, The receiver of the command mode is saved as an attribute of the command object, and the command execution operation is agreed to call the command.execute method. However, if we use the callback function, then the receiver is closed in the environment where the callback function is generated, and the execution operation will be simpler. Only the callback function can be executed. Let's look at the following code:
