When to Choose Behavioral Design Patterns?
According to this Design Patterns Cheat Sheet, choose behavioral design patterns when you need to manage algorithms, communication, or responsibilities between objects. They’re useful for encapsulating behavior that varies and promoting loose coupling between objects.
- Behavioral patterns facilitate code reuse, flexibility, and maintainability by defining how objects interact and communicate.
- Use them to address scenarios like handling complex workflows, managing state transitions, or implementing communication between objects.
We must choose Behavioral Design Patterns when the Problem is related to Object Interactions.
- Observer: Observes and notifies changes in multiple objects.
- Strategy: Encapsulates the interchangeable algorithms.
- Command: Encapsulates requests as objects for decoupled execution.
- State: It Changes the behavior of object with internal state.
- Visitor: It separates algorithms from objects.
- Memento: Pattern to manage object state and actions.
- Iterator: It Sequentially accesses the elements of a collection.
- Mediator: Central controller managing communication between objects.
- Chain of Responsibility: Pass request through handlers until one handles it.
- Template Method: Defines the skeleton of an algorithm.
Design Patterns Cheat Sheet – When to Use Which Design Pattern?
In system design, selecting the right design pattern is related to choosing the right tool for the job. It’s essential for crafting scalable, maintainable, and efficient systems. Yet, among a lot of options, the decision can be difficult. This Design Patterns Cheat Sheet serves as a guide, helping you on the path toward optimal design pattern selection. Simplifying complex concepts into easy insights empowers engineers to navigate design patterns confidently.
