\modMediaSource
An abstract base class used for determining functionality of different media source drivers. Extend this class in and implement modMediaSourceInterface in your driver implementations to provide custom functionality for different types of media sources.
Of course, in your getContainerList method, you can define the context menu items for the tree, so not all of these methods might need to be implemented, depending on your situation. You can also provide custom actions for your source type, depending on the behavior you might need.
