When to use the Mediator Design Pattern
- Complex Communication: Your system involves a set of objects that need to communicate with each other in a complex manner, and you want to avoid direct dependencies between them.
- Loose Coupling: You want to promote loose coupling between objects, allowing them to interact without knowing the details of each other’s implementations.
- Centralized Control: You need a centralized mechanism to coordinate and control the interactions between objects, ensuring a more organized and maintainable system.
- Changes in Behavior: You anticipate changes in the behavior of components, and you want to encapsulate these changes within the mediator, preventing widespread modifications.
- Enhanced Reusability: You want to reuse individual components in different contexts without altering their internal logic or communication patterns.
Mediator design pattern
The Mediator design pattern is a behavioral pattern that defines an object, the mediator, to centralize communication between various components or objects in a system. This promotes loose coupling by preventing direct interactions between components, instead of having them communicate through the mediator, facilitating better maintainability and flexibility in the system architecture.
