Facade
From CSSEMediaWiki
The facade pattern is used to provide a simple interface to a complex set of interfaces. Often facades are produced to further simplify common APIs or adapt them to a more specific use.
The design pattern
- provides convenient methods
- makes the inner system more flexible since less methods are called from the outside
- can turn a badly designed API into a very well usable one
Example
The boot process of a computer can be modeled as a Facade. The system's boot() method is called. This method now starts and configures all the services and programs needed to use the computer.
