#INTERFACE SEGREGATION PRINCIPLE SOFTWARE#
So in short the interfaces should also follow the first rule of SOLID i.e Single Responsibility Principle. Similar to the Single Responsibility Principle, the goal of the Interface Segregation Principle is to reduce the side effects and frequency of required changes by splitting the software into multiple, independent parts. Martin while consulting for Xerox to help them build the software for their new printer systems. The Interface Segregation Principle was first used and formulated by Robert C. The Interface Segregation Principle is the fourth SOLID Design Principle. Segregation means keeping things separated, and the Interface Segregation Principle is about separating the interfaces.
So, if you need a larger interface in some parts of the application, but not in others, you can compose it from two or more other interfaces as well. In many OOPS languages like C#, interfaces can inherit from multiple other interfaces. This will prevent you from ending up with one-interface-per-method most of the time in real-world systems. Another benefit of smaller interfaces is that they are easier to implement fully, and therefore less likely to break the Liskov Substitution Principle by being only partially implemented. Ideally, your thin interfaces should be cohesive, meaning they have groups of operations that logically belong together. Application developers should favor thin and focused interfaces compared to "fat" interfaces that offer more functionality than a particular class or method needs. Interfaces should belong to clients, not to libraries or hierarchies. ISP is intended to keep a system decoupled so that it is easier to refactor, change, test and redeploy. Using interfaces is one of the best ways to allow the extensibility and testability of the application. This principle is related to the Single Responsibility Principle in that even interfaces also should have a single purpose. Segregation means keeping things separated, and the Interface Segregation Principle is about separating the interfaces. In the SOLID acronym, the fourth letter "I" represents the " Interface Segregation Principle". Please read the previous parts here over the below links: In this part, we will walk through the 4th SOLID Design Principle i.e Interface Segregation Principle (ISP) in detail with live real examples. This is the 5th part of the SOLID Design Principle. This rule also includes modules and functions.SOLID Principles are one of the mandatory questions in each and every interview.
Let’s get started!Īccording to the single-responsibility principle, a class should be responsible for only one activity and only have one cause to change. In this article, we’ll go over each of the SOLID principles, providing TypeScript examples to illustrate and understand them. The abbreviation SOLID was later coined by Michael Feathers to illustrate the ideas identified by Uncle Bob.

He’s also known for the best-selling books Clean Code and Clean Architecture. Martin, popularly known as Uncle Bob, credit for this idea in his 2000 work, Design Principles and Design Patterns. The five SOLID principles of object-oriented class design facilitate the development of understandable, tested software that many developers can use at any time and place. Applying SOLID principles to TypeScriptĭefined long ago, the SOLID principles are intended to improve the readability, adaptability, extensibility, and maintainability of object-oriented designs.
