I found that the experts around me have two skills higher than ordinary people: one is the ability to see problems and the other is the ability to solve problems. For most people, they work very hard but do not get the desired results. Many things, have attitude, but at a loss to come up with a specific solution to the problem. In this era of mobile Internet with great social development and information explosion, it is an inextricable competitive skill for our contemporary people to be able to quickly build an effective knowledge system through some fragmented information points. "Deliberate Practice" and "The Way to Learn" are two good books for us to improve the practice effect.

What we understand is that if a single schema is instantiated, it will only be instantiated once. To implement a single schema, we simply use a variable to identify whether the class is instantiated. If it is not instantiated, then we can instantiate it once. Otherwise, we will directly return the instantiated object.

User class unified interface, User1 and User2 are different objects respectively, and they are related. If the mediator mode is not adopted, the two need to hold references to each other, so the coupling degree between the two is very high. In order to decouple, the Mediator class is introduced to provide unified interface, and MyMediator is its implementation class, which holds instances of User1 and User2 to control User1 and User2. In this way, User1 and User2 objects are independent of each other. They only need to maintain a good relationship with the Mediator, and the rest is maintained by the MyMediator class! Basic implementation:
The reason why the logic for creating an object is put into a separate class is that it can be used by multiple clients. And separates the creation and use of objects. However, this design also has many defects. First of all, SimpleFactory is a specific class, so we must program for the implementation, making the system lose its flexibility in this respect. Second, if we add new products, we have to modify the code in SimpleFactory, which violates the opening and closing principle. The above model is also called simple factory. He does not appear in GOF mode, it is more like a programming habit.
Role, record the internal status at the current time, be responsible for creating memos and restoring the internal status with memos.
If the actions modified by the current user reach a certain value, such as 50, the system will automatically pop up the window being saved and save the mind map.
