A CarSensorEvent object corresponds to a single sensor event coming from the car. The sensor data is stored in a sensor-type specific format in the object's float and byte arrays. To aid unmarshalling the object's data arrays, this class provides static nested classes and conversion methods. The conversion methods each have an optional data parameter which, if not null, will be used and returned. This parameter should be used to avoid unnecessary object churn whenever possible. Additionally, calling a conversion method on a CarSensorEvent object with an inappropriate type will result in an`UnsupportedOperationException`being thrown.
