QgisInterface Abstract base class defining interfaces exposed by QgisApp and made available to plugins.
Only functionality exposed by QgisInterface can be used in plugins. This interface has to be implemented with application specific details.
QGIS implements it in QgisAppInterface class, 3rd party applications could provide their own implementation to be able to use plugins.
