Plugins can be implemented around marble.
The interface for plugins relies on the PluginInterface base class. All plugins will have their lifecycle managed by the PluginManager.
They will thereafter be managed by another class handling them.
There are different categories such as:
They inherit from NetworkPluginInterface They are manipulated by an HttpDownloadManager
They inherit from PositionProviderPluginInterface They are manipulated by the PositionTracking for now, and a new manager that tracks the history of positions should be implemented to replace the old gps layer.
They inherit from RenderPluginInterface
