Decoration Mode C #1. OverviewDecorator Pattern. The decoration mode dynamically extends the functions of an object without changing the original class file and using inheritance. It creates a packaging object, that is, decoration, to package a real

Interpreter mode (C ++ Interpreter Mode) The Interpreter mode provides a framework for implementing the syntax Interpreter. The purpose is to use an Interpreter to provide a Interpreter that defines the syntax representation of a language, the

Design Mode-specification Mode C #The application scenario of the Protocol mode is rules, and the business rules are fragmented.The combination of business rules is not fixed and needs to be easily combined or split. The Protocol mode is an

Transforms the interface of one class into another interface that the customer Wants. The adapter mode makes it possible for those classes that would otherwise not work together because of incompatible interfaces to work Together.There are three

Implementation of policy Mode C ++ in Design Mode Strategy: defines the algorithm family and encapsulates them separately so that they can replace each other. This pattern changes the algorithm and does not affect the customers who use the algorithm.

　　Builder mode: Separates the representation of a complex object from its implementation so that it can construct a non-accessible representation under the same construction.　　The above words may not be very clear, for example, I understand. Suppose
