fasadefunksjoner

Fasadefunksjoner, or facade functions, are a software design pattern used to simplify the interface of a complex subsystem. Instead of interacting directly with numerous individual components within a subsystem, a client can interact with a single facade object. This facade object then delegates the requests to the appropriate components within the subsystem, hiding the underlying complexity. The primary goal of the facade pattern is to provide a higher-level interface that makes the subsystem easier to use.

This pattern can be particularly useful when dealing with a large or intricate system that has many dependencies. By presenting a simplified view, the facade reduces the coupling between the client code and the subsystem. This makes the client code more independent and easier to maintain, as changes within the subsystem are less likely to affect the client. The facade itself does not add new functionality but rather acts as a wrapper or a mediator.

Implementing a facade involves creating a new class that exposes a set of methods representing common operations that clients might need. These methods internally call the services provided by the various classes within the subsystem. It's important that the facade does not become a "god object" by trying to do too much; its scope should be limited to providing a convenient and simplified interface to a specific subsystem.
