In object-oriented programming, the open/closed principle states "software entities (classes, modules, functions, etc.) should be open for extension, but closed for modification"; that is, such an entity can allow its behaviour to be extended without modifying its source code.The name open/clos...

正如牛顿三大定律在经典力学中的位置一样,“开-闭”原则(Open-Closed Principle)是面向对象的可复用设计(Object Oriented Design或OOD)的基石。其他设计原则(里氏代换原则、依赖倒转原则、合成/聚合复用原则、迪米特法则、接口隔离原则)是实现“开-闭”原则的手段和工具。
To create a code that abides by the Open Closed Principle, we are going to create an abstract class first: publicabstractclassBaseSalaryCalculator { protectedDeveloperReportDeveloperReport{get;privateset;} publicBaseSalaryCalculator(DeveloperReportdeveloperReport) ...
In this file, I create the following “BankAccount” class. // Not following the Open Closed Principle public enum AccountType { SavingsAccount = 1, LongTermSavingsAccount = 2 } public class BankAcount { public string AccountNumber { get; set; } public string AccountTitle { ...
主题简介:开放封闭原则是面向对象设计中的一个重要设计原则,也是SOLID原则中的一员。该原则强调软件实体(类、模块、函数等)应该是可扩展的(Open for extension),而不可修改的(Closed for modification)。换句话说,当需要对系统进行改动时,应该通过扩展现有代码来实现,而不是直接修改现有代码。在本文中,我们将深入讨论...
设计模式重在设计阶段,封装变化点,预留扩展。而不是在需求变化时再来讨论类的继承扩展组合修改等等。 用抽象构建框架,用实现扩展细节。 框架在设计阶段就确认,细节在后期变化修改进行扩展。 在设计阶段就考虑好变化点,把变化点抽象并封装,把整个框架骨骼搭起来。后期需求变化的时候,扩展抽象的变化点,对现有框架骨骼不...
开-闭原则(Open-Closed Principle, OCP)是面向对象的可复用设计的基石。开-闭原则是指一个软件实体应当对(37) 开放,对(38) 关闭;里氏代换原则(Liskov Substitution Principle, LSP)是指任何(39) 可以出现的地方,(40) 一定可以出现。依赖倒转原则(Dependence Inversion Principle, DIP)就是要依赖于(41) ,而不...
