Design Patterns
Explanation
- Target Interface: Defines the interface expected by the client (ITarget and ILogger).
- Adaptee: Represents the existing class with an incompatible interface (LegacySystem and ThirdPartyLogger).
- Adapter: Implements the target interface and translates requests from the client to the adaptee (Adapter and LoggerAdapter).
- Client: Uses the target interface to interact with the adapter, which in turn interacts with the adaptee.
Summary
The Adapter Pattern is a powerful tool when dealing with legacy code or third-party libraries that do not match the expected interface of your application, allowing for smoother integration and more maintainable code.
General Tips!
- Identify Common Problems: Recognize recurring problems in your code to determine which design pattern can provide a solution.
- Understand the Principles: Familiarize yourself with SOLID principles as they often align with the motivations behind design patterns.
- Use Patterns Judiciously: Avoid overusing patterns; apply them only when they provide a clear benefit.
- Learn by Example: Study real-world examples of design patterns to see how they are implemented in practice.
- Refactor When Necessary: Don’t force a pattern from the start; refactor your code to introduce patterns when a need becomes apparent.
- Stay Flexible: Patterns are guidelines, not strict rules. Adapt them to fit your specific context.
- Document Your Design: Clearly document the use of design patterns to help future maintainers understand your design decisions.
