2.里氏代换原则(Liskov Substitution Principle,常缩写为.LSP) (1).由Barbar Liskov(芭芭拉.里氏)提出,是继承复用的基石。 (2).严格表达:如果每一个类型为T1的对象o1,都有类型为T2的对象o2,使得以T1定义的所有程序P在所有的对象o1都代换称o2时,程序P的行为没有变化,那么类型T2是类型T1的子类型. 换言之,一...
Below is the classic example for which the Liskov's Substitution Principle is violated. In the example, 2 classes are used: Rectangle and Square. Let's assume that the Rectangle object is used somewhere in the application. We extend the application and add the Square class. The square class ...

The Liskov Substitution Principle (LSP) is a concept in object-oriented programming that states that if a program is using a base class, it should be able to use any of its subclasses without the program knowing it. In simpler terms, it means that objects of a superclass should be able ...

This article presents a perspective of Liskov Substitution Principle (LSP) and presents an argument against some interpretation and practices of LSP that some people have/follow.
This seems to violate the Liskov Substitution Principle (LSP): if S is a subtype of T, then objects of type T may be replaced with objects of type S Is this a violation of LSP? Does it matter if it is or not? Principles aside, this looks rather silly: u = s // Erro...
1 The Liskov Substitution Principle This is the second of my Engineering Notebook columns for The C++ Report . The articles that will appear in this column will focus on the use of C++ and OOD, and will address issues of software engineer- ing. I will strive for articles that are pragmati...
