Method Summary

java.lang.Object	clone() Return a Point2D equals() to this one
boolean	equals(java.lang.Object o) True if o is not null, from the Point2D class without beeing from a subclass, and have the same coordinates in the same order than this.
double	getDistanceTo(Point2D pt) Get the distance between this and the given Point
Point2D	getTranslated(Vector2D v) Get the point corresponding to this translated by the given vector
Vector2D	getVector() Get the Vector corresponding to the translation from the origin to this Point
Vector2D	getVectorTo(Point2D pt) Get the vector between this and the given Point
java.lang.String	toString() Get this point as a string
void	translate(Vector2D v) Translate this point using the given vector
