The so-called design patterns that people will develop the solution to the problem encountered repeatedly summed up .
Design from life, all design patterns can be constructed with the real world imaginable. How will these concepts, principles, using easy to understand, more vivid words to describe my mind.
Pattern Classification
| Range \ purpose | Creating type | Structural | Behavioral |
|---|---|---|---|
| Class mode | Factory Method pattern | (Category) adapter mode | Interpreter pattern Template Method Pattern |
| Object Model | Abstract factory pattern builder pattern prototype pattern singleton |
(Object) adapter mode bridge mode combination pattern decorative patterns appearance mode Flyweight proxy mode |
Duty chain command mode iterative mode intermediary model memorandum mode observer mode state mode strategy pattern Visitor Pattern |
According to the intended use classification
According to different purposes of use, these modes can be roughly divided into three categories.
1. Create type
Create a design model is something about the way to create objects . You can choose to create objects using appropriate way according to the actual situation.
The traditional way to create a new class objects may cause some design issues, or increase the complexity of the design.
Using the appropriate creational design patterns you can solve this problem.
2. Structural
Structural design pattern is to describe how the classes and objects together to form larger structures .
Like building blocks to form complex, more powerful structure you available by combining simple building blocks.
3. Behavioral
Behavioral design pattern is to describe the interaction and responsibilities assigned class or object .
According to the scope of the classification process
Depending on the processing range, pattern design mode can be divided into classes and object model.
1. Mode Class
Class models handle the relationship between classes and subclasses to build these relationships by inheritance, are static relationships , finalized at compile time.
2. Object Model
Object model dealing with the relationship between objects , when the change operation, is the dynamic relationship .
