public interface PositionConstants

Constants representing cardinal directions and relative positions. Some of these constants can be grouped as follows:

LEFT, CENTER, RIGHT Used to describe horizontal position.

TOP, MIDDLE, BOTTOM Used to describe vertical position.

NORTH, SOUTH, EAST, WEST Used to describe the four positions relative to an object's center point. May also be used when describing which direction an object is facing.
NOTE: If you have a use for all four of these possibilities, do not use TOP, BOTTOM, RIGHT, LEFT in place of NORTH, SOUTH, EAST, WEST.
