AccelerometerDatum class

A Datum that holds acceleration data collected from the native accelerometer on the phone. Accelerometers measure the velocity of the device. Note that these readings include the effects of gravity. Put simply, you can use accelerometer readings to tell if the device is moving in a particular direction.

hashCode → int
The hash code for this object.
no setterinherited
id ↔ String?
An identifier for this Datum, unique across all data generated. If this datum is part of a MultiDatum, then this id is null.
