+ * The ISensorsWrapper interface includes all function from supported Sensors HAL versions. This
+ * allows for the SensorDevice to use the ISensorsWrapper interface to interact with the Sensors
+ * HAL regardless of the current version of the Sensors HAL that is loaded. Each concrete
+ * instantiation of ISensorsWrapper must correspond to a specific Sensors HAL version. This design
+ * is beneficial because only the functions that change between Sensors HAL versions must be newly
+ * newly implemented, any previously implemented function that does not change may remain the same.
+ *
+ * Functions that exist across all versions of the Sensors HAL should be implemented as pure
+ * virtual functions which forces the concrete instantiations to implement the functions.
+ *
+ * Functions that do not exist across all versions of the Sensors HAL should include a default
+ * implementation that generates an error if called. The default implementation should never
+ * be called and must be overridden by Sensors HAL versions that support the function.
