All Implemented Interfaces:

Comparable, Serializable

Direct Known Subclasses:

Place

public class Location

extends Location2D

A location is simply a point on the planet. There may not be a weather station at this point. This abstraction is intended to support GIS type applications where data must be synthesised over a regular grid, irrespective of the location of individual stations The class is made final because it overrides the equals method. If any classes extend this and add a field then the equals method of this class is likely to not be transitive.

Method Detail

toString

public String toString()

Overrides:

toString in class Location2D

getAltitude

public double getAltitude()

compareTo

public int compareTo(Object a)

More northerly locations sort first. If latitude is the same, more more westerly (lesser longitude) locations sort first. If latitude and longitude are the same, boxes with higher altitude sort first.

Specified by:

compareTo in interface Comparable

Overrides:

compareTo in class Location2D

equals

public boolean equals(Object o)

Tests whether two objects represent the same Location.

Overrides:

equals in class Location2D

Parameters:

o - the other object

Returns:

true if the other object is a Location with the same latitude, longitude, and altitude

hashCode

public int hashCode()

Overrides:

hashCode in class Location2D
