Class WangTile

public class WangTile

Associates one local tile ID with the terrains at its four corners and four edges.

Wang IDs always contain eight entries in Tiled order. Zero means no terrain; positive values are one-based indexes into WangSet.getTerrains(). Arrays supplied to or returned from this class are defensively copied.
