GenericController class
This Class Acts as an intermediate class to relay storageRequests to the StorageMapper.
This class contains the interaction API every actor (sensor, shields, UI,...) calls methods from this controller to manipulate data.
- Implemented types
Constructors
- GenericController(String _owner, StorageMapper mapper)
- Construct the controller according to the database that is used.
