public class Position extends Object
The org.osgi.util.measurement.Measurement
class is used to
represent the values that make up a position.
A given position object may lack any of it's components, i.e. the altitude may not be known. Such missing values will be represented by null.
Position does not override the implementation of either equals() or
hashCode() because it is not clear how missing values should be handled. It
is up to the user of a position to determine how best to compare two position
objects. A Position
object is immutable.
