Introduction
The Adapter pattern allows incompatible interfaces to work together by acting as a middleman that translates one interface into another.
Real-Life Example
A power plug adapter: A European device with a round plug won’t fit into a North American outlet, but an adapter allows seamless connection without modifying the device itself.
Pros
Enables integration of existing components without modification.
Improves code maintainability by standardizing interfaces.
Supports legacy code migration.
Cons
Can lead to excessive wrappers if not managed properly.
May introduce slight performance overhead due to extra translation.
When to Use It
When working with legacy code that needs to integrate with modern systems.
When connecting third-party libraries with incompatible interfaces.
Avoid when a simpler refactor can solve the incompatibility.
Conclusion
Adapter is an essential tool for bridging systems, but excessive use can make code harder to maintain.
