interface 2. Plugins - Stand-alone independent components that contain implementation of core application’s features 3. Plugin Manager - Component responsible for loading and unloading plugins Core use plugin architecture? ● More testable code ○ Interface can be mocked to test core system ○ Plugins can be individually tested ● Simplifies integration ○ Core system has a well defined API ○ Increase have to compile the entire project ● Plugins are be loaded, updated and deleted on the fly without application restart 8Some popular C++ projects that use plugins 9 ● Audio editing software ● Game
