public class LatRange

extends Sphere

LatRange class - provide services and information relating to a latitude range. At the moment it's all fairly basic, but at some point we may need to add functionality for circular latitudes.

This class assumes a spherical earth.

Field Summary

double	max maximum latitude in range.
double	min minimum latitude in range.

Field Detail

min

public double min

minimum latitude in range.

max

public double max

maximum latitude in range.

                double givenMax)

The constructors.

LatRange

public LatRange(float givenMin,
                float givenMax)

Method Detail

contains

public boolean contains(float lat)

Determine if the given latitude is within the range.

contains

public boolean contains(double lat)

Determine if the given latgitude is within the range.

overlaps

public boolean overlaps(LatRange other_range)

Determine if this range overlaps another.

meldRange

public boolean meldRange(LatRange other_range)

Combine two ranges if possible.
If the two ranges overlap this range is adjusted to include the other and true is returned. The other range can then be discarded by the calling method.
If the two ranges do not overlap no changes are made and false is returned.

meldRange

public boolean meldRange(double otherMin,
                         double otherMax)

Combine two ranges if possible.
If the two ranges overlap this range is adjusted to include the other and true is returned. \n
If the two ranges do not overlap no changes are made and false is returned.

toString
