Question

I\'m programming a game in java which is made up of a grid of tiles. I wan\'t to be able to inuitively define the edges of the tiles and how they relate to each other, e.g.

You can also make use of an static innerclass inside the enum:

public enum EnumTest     
{     
NORTH( Orientation.VERTICAL ),     
SOUTH( Orientation.VERTICAL ),     
EAST( Orientation.HORIZONTAL ),     
WEST( Orientation.HORIZONTAL );     

private static class Orientation  
{  
private static final String VERTICAL = null;     
private static final String HORIZONTAL = null;     
}
}

Stolen from here :)
