Overview ¶
Package facade implements the Facade design pattern. HomeTheater provides a simplified interface for controlling a group of devices: Projector, MediaServer, Lights, and SoundSystem. It encapsulates the logic required to coordinate these components in the correct sequence, allowing viewers to prepare for, play, and shut down a movie session through a single high-level interface.
