我和小姨子

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.郑中、郑发和郑白三兄弟是香港云吞面店“郑记”的继承人，作为继承人的三兄弟中却只有老大郑中愿意继承祖业，老二郑发醉心于影视表演，老三郑白则一心想做一名教师。但老大郑中不善经营，当年门庭若市的云吞面生意日渐冷清，此时曾被郑家开除的郑记旧员工刘诚竟变成富豪，于郑记对面开设新派经营的“天下第一”面店，欲向郑家报复，打击其生意。郑记生意暴跌，走投无路，郑中却在一次偶然的“相亲”中认识了退隐江湖的味王李炳焕之女儿，从此在味王的面店打工。同时，刘诚向味王提出比赛，并派有名的英俊厨神Jack出战，而味王则派郑中应战，最后郑中胜出。味王答应为郑家重振祖业，并且寻找昔日部下重出江湖……The two long voices were followed by a short one, indicating that "our ship is trying to overtake your starboard side";?

The virtual agent is used to control access to the ontology with high creation cost. It will postpone the instantiation of the ontology until a method is called. For example, if the instantiation of an object is very slow now, it cannot be completed immediately when the web page is loaded. We can create a virtual agent for it and let it postpone the instance of the object until it is needed.
