What is the Mediator Pattern in software design?

Can you explain the Mediator Pattern in software design?

Sure! The Mediator Pattern is a behavioral design pattern that allows objects to communicate with each other without knowing about each other's internal details. It promotes loose coupling by having a mediator object handle the communication.

Can you give me a real-world example of the Mediator Pattern?

Absolutely! A common example is a chat application where the chat room acts as a mediator. Users send messages to the chat room, which then distributes those messages to all participants, allowing them to communicate without directly referencing each other.

What are the benefits of using the Mediator Pattern?

The benefits include reduced dependencies between components, easier maintenance, and improved scalability. It also centralizes communication logic, making it easier to manage.

Are there any drawbacks to using this pattern?

Yes, one drawback is that it can lead to a single point of failure if the mediator becomes too complex. Additionally, it may introduce overhead in communication.
