Facade Design Pattern
Discover how to use the Facade design pattern in Kotlin to create simpler interfaces that hide complex interactions among multiple classes. Understand how this pattern provides a cleaner way to work with configurations and improve code maintainability by encapsulating complex logic in user-friendly functions.
We'll cover the following...
The use of “facade” as a term to refer to a design pattern comes directly from building architecture. That is, a facade is the face of a building that is normally made to look more appealing than the rest of it. In programming, facades can help to hide the ugly details of an implementation.
The Facade design pattern itself aims to provide a nicer, simpler way to work with a family of classes or interfaces. As we know, the Abstract Factory design pattern focuses on creating related classes, while the Facade design pattern focuses on working with those classes once they have been created.
To better understand this, let’s assume we have a configuration for our server written in a YAML file:
