net.rim.device.api.lbs.maps.model.MapPoint
public class MapPoint
Represents the coordinates for a location point on a map.
Note: The conversion to and from a Coordinates
object is not symmetric. If a Coordinates object is converted to a
MapPoint object and then it is converted back to a
Coordinates object, the result might not equal the
original.

public int hashCode()
Objectjava.util.Hashtable.
The general contract of hashCode is:
hashCode method on each of
the two objects must produce the same integer result.
Object.equals(java.lang.Object)
method, then calling the hashCode method on each of the
two objects must produce distinct integer results. However, the
programmer should be aware that producing distinct integer results
for unequal objects may improve the performance of hashtables.
As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)
hashCode in class AbstractMappableObject.hashCode()public boolean equals(Object obj)
Object
The equals method implements an equivalence relation:
x,
x.equals(x) should return true.
x and
y, x.equals(y) should return
true if and only if y.equals(x) returns
true.
x,
y, and z, if x.equals(y)
returns true and y.equals(z) returns
true, then x.equals(z) should return
true.
x
and y, multiple invocations of x.equals(y)
consistently return true or consistently return
false, provided no information used in
equals comparisons on the object is modified.
x,
x.equals(null) should return false.
The equals method for class Object implements
the most discriminating possible equivalence relation on objects;
that is, for any reference values x and y,
this method returns true if and only if x and
y refer to the same object (x==y has the
value true).
equals in class AbstractMappableobj - the reference object with which to compare.
true if this object is the same as the obj
argument; false otherwise.Object.equals(Object)public int compareTo(Object other)
ComparableIn the foregoing description, the notation sgn(expression) designates the mathematical signum function, which is defined to return one of -1, 0, or 1 according to whether the value of expression is negative, zero or positive.
The implementor must ensure sgn(x.compareTo(y)) == -sgn(y.compareTo(x)) for all x and y. (This implies that x.compareTo(y) must throw an exception iff y.compareTo(x) throws an exception.)
The implementor must also ensure that the relation is transitive: (x.compareTo(y)>0 && y.compareTo(z)>0) implies x.compareTo(z)>0.
Finally, the implementer must ensure that x.compareTo(y)==0 implies that sgn(x.compareTo(z)) == sgn(y.compareTo(z)), for all z.
It is strongly recommended, but not strictly required that (x.compareTo(y)==0) == (x.equals(y)). Generally speaking, any class that implements the Comparable interface and violates this condition should clearly indicate this fact. The recommended language is "Note: this class has a natural ordering that is inconsistent with equals."

ObjecttoString method returns a string that
"textually represents" this object. The result should
be a concise but informative representation that is easy for a
person to read.
It is recommended that all subclasses override this method.
The toString method for class Object
returns a string consisting of the name of the class of which the
object is an instance, the at-sign character `@', and
the unsigned hexadecimal representation of the hash code of the
object. In other words, this method returns a string equal to the
value of:
getClass().getName() + '@' + Integer.toHexString(hashCode())
