Real World Application Of Bridge Pattern

Sure, I can provide several real-world scenarios where the Bridge pattern might be appropriate:

Graphic Libraries

Here's a class diagram created using Mermaid markdown for the Graphic Libraries example. I'll assume two types of shapes (Circle, Rectangle) and two types of renderers (OpenGL, DirectX).

In this diagram:

• Shape is the abstraction that client code interacts with.
• Circle and Rectangle are concrete abstractions.
• Renderer is the implementor interface.
• OpenGL and DirectX are concrete implementors.
• Shape uses a Renderer to carry out its operations.

This would allow you to add more shapes or rendering APIs in the future without affecting existing code.

Suppose you're creating a graphics library that should work with multiple rendering APIs (like OpenGL, DirectX, etc.). These APIs have their own way of drawing lines, curves, and other shapes. Now, a client wants to draw different shapes using your library but doesn't want to worry about the specifics of the rendering APIs.

Here, you can use the Bridge pattern to create an abstraction of the shape (Shape) and its implementation (Renderer). The Shape abstraction can represent different types of shapes (like a circle, square, etc.), and the Renderer can represent different rendering APIs. This way, the client code can work with the Shape abstraction, and the specifics of rendering are hidden in the Renderer implementation.

Cross-platform Apps

Here's a class diagram created using Mermaid markdown for the Cross-platform Apps example. I'll assume two types of operations (CreateWindow, HandleEvent) and two types of platforms (Windows, Linux).

In this diagram:

• Operation is the abstraction that client code interacts with.
• CreateWindow and HandleEvent are concrete abstractions.
• Platform is the implementor interface.
• Windows and Linux are concrete implementors.
• Operation uses a Platform to carry out its operations.

This would allow you to add more operations or platforms in the future without affecting existing code.

If you're developing an application that needs to run on multiple platforms ( Windows, Linux, macOS, etc.), the Bridge pattern can be very useful. Here, the abstraction could represent high-level operations like creating a window, handling events, etc., and the implementations could represent platform-specific details.

With this approach, you can develop the high-level code without worrying about the platform specifics. When you need to support a new platform, you just need to add a new implementation.

Different Database Systems

Here's a class diagram created using Mermaid markdown for the Different Database Systems example. I'll assume two types of services (UserDataService, OrderDataService) and two types of databases (PostgreSQL, MongoDB).

In this diagram:

• DataService is the abstraction that client code interacts with.
• UserDataService and OrderDataService are concrete abstractions.
• Database is the implementor interface.
• PostgreSQL and MongoDB are concrete implementors.
• DataService uses a Database to carry out its operations.

This would allow you to add more services or databases in the future without affecting existing code.

As we discussed in the previous examples, if your application needs to interact with different types of databases (like PostgreSQL, MongoDB, etc.), each having its own way of connecting, executing queries, and closing the connection, the Bridge pattern can be used to create a uniform interface for the client to interact with these databases while hiding the specifics.

In each of these scenarios, the Bridge pattern is beneficial because it allows the abstraction and implementation to vary independently. This makes the software more flexible to future changes and additions. It also improves the code's readability and maintainability by separating high-level logic from low-level details.
