Interface Segregation Principle - Getting Solid with SOLID - Part 4

Software engineering, like other trades, is something that can be done in many ways. Throughout the years people have established patterns and practices to help craft good software. One set of design principles we’ve been discussing is SOLID. Robert C. Martin coded the Interface Segregation Principle (ISP) which “I” represents.

Today’s post is fourth in a five part series. You can find the first parts here: Single Responsibility Principle, Open/Closed Principle, and Liskov Substitution Principle.

S.O.L.I.D. Software Design Principles To Help You Become A Better Developer

S.O.L.I.D design principle comes from Object oriented programming guidelines. It is designed to develop software that can be easily maintained and extended; prevents code smells; easy to refractor; promotes agility and finally incorporates rapid + frequent changes quickly without bugs.

Generally, technical debt is the result of prioritising speedy delivery over perfect code. To keep it under control - use SOLID principles, during development.

Robert Martin, is credited with writing the SOLID principles and stated 4 major software issues if S.O.L.I.D is not followed diligently. They are :

Rigidity:

Implementing even a small change is difficult since it’s likely to translate into a cascade of changes.

Fragility:

Any change tends to break the software in many places, even in areas not conceptually related to the change.

Immobility:

We’re unable to reuse modules from other projects or within the same project because those modules have lots of dependencies.

Viscosity:

Difficult to implement new features the right way.

SOLID is a guideline and not a rule. It is important to understand the crux of it and incorporate it with a crisp judgement. There can be a case when only few principles out of all is required.

How to apply SOLID Software Design Principles to Spring Boot Application (Part 2)

OCP: Open-Closed Principle

(skip the first paragraph if you have already read other parts of this blog series)

This article is the second part of the blog series, dedicated to well-known software design principles, that evolved over time and were finally summarised by Robert C. Martin with initials of the corresponding principles. These principles guide us how to build well-designed software systems, giving best practices for arranging classes, functions, building blocks. We will look at each principle in depth and apply it to the Spring Boot Application. The idea is refactoring existing software based on these principles from architectural point of view.

The word S.O.L.I.D. stands for:

  • SRP: Single Responsibility Principle
  • OCP: Open-Closed Principle
  • LSP: Liskov Substitution Principle
  • ISP: Interface Segregation Principle
  • DIP: Dependency Inversion Principle

This second part is about OCP. Before jumping to concrete example, let’s have some theory.

A Software artifact should be open for extension but closed for modification.

This simple description of the principle was firstly introduced by Bertrand Meyer. Software system that needs modification each time for any additional functionality is just a big mess. On the other hand, this kind of chaotic program is welcoming occasional bugs every time modification is made. Preferably, every new functionality should be maximum of new code and minimum of change in old code, in ideal world: zero changes in old code.

From architectural point of view, before structuring any software system every developer should think carefully which components should be free of any changelings, and organize dependency flow so that important components (plugins, packages, classes…) should not need changes when less important components are changed. So dependency flow of a software should be directed to components that you want to protect the most.

If component A should be protected from changes in component B, then component B should depend on component A, not otherwise.

Luckily, capabilities of Object Oriented Programming are able to handle these kind of problems. Polymorphism, by using super/child classes and Inversion of Control, by using interfaces(in java terms!) are two powerful technics that we can use to achieve Open-Closed Principle.

Polymorphism means “many forms”, and it occurs when we have many classes that are related to each other by inheritance.

Inversion of control (IoC) is inverting the flow of control as compared to traditional control flow.

SOLID in C# - The Interface Segregation Principle

The Interface Segregation Principle states that no client code object should be forced to depend on methods it does not use. Basically, each code object should only implement what it needs, and not be required to implement anything else.

The ISP is all about reducing code objects down to their smallest possible implementation, and removing dependencies the object doesn’t need to function properly. The result of implementing this principle, generally speaking, is to have a lot of small, focused interfaces that define only what is needed by their implementations.
