Fields
public static final Distance UNKNOWN
Represents an unknown distance, with accuracy = Distance.Accuracy.LOW,
and meters = Double.NaN.
Public Methods
public abstract int compareTo (Distance other)
Note: This compares only getMeters(),
not accuracy. We also consider NaN == NaN, so that UNKNOWN.equals(UNKNOWN).
public abstract int getAccuracy ()
The accuracy of the distance estimate.
public abstract double getMeters ()
The distance estimate, in meters.
