Constructor Detail

ResultPoint

public ResultPoint(float x,
                   float y)
Since:
BlackBerry API 6.0.0


Method Detail

getX

public final float getX()
Since:
BlackBerry API 6.0.0

getY

public final float getY()
Since:
BlackBerry API 6.0.0

equals

public boolean equals(Object other)
Description copied from class: Object
Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation:

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).

Overrides:
equals in class Object
Parameters:
other - the reference object with which to compare.
Returns:
true if this object is the same as the obj argument; false otherwise.

BlackBerry API 6.0.0

hashCode

public int hashCode()
Description copied from class: Object
Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided by java.util.Hashtable.

The general contract of hashCode is:

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.)

Overrides:
hashCode in class Object
Returns:
a hash code value for this object.
See Also:
Object.equals(java.lang.Object), Hashtable
Since:
BlackBerry API 6.0.0

toString

public String toString()
Description copied from class: Object
Returns a string representation of the object. In general, the toString 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())
 

Overrides:
toString in class Object
Returns:
a string representation of the object.

BlackBerry API 6.0.0

orderBestPatterns

public static void orderBestPatterns(ResultPoint[] patterns)

Orders an array of three ResultPoints in an order [A,B,C] such that AB < AC and BC < AC and the angle between BC and BA is less than 180 degrees.

Since:
BlackBerry API 6.0.0

distance

public static float distance(ResultPoint pattern1,
                             ResultPoint pattern2)
Returns:
distance between two points
Since:
BlackBerry API 6.0.0
