Class PointCache

java.lang.Object
  wyvern.lib.PointCache

public final class PointCache

extends java.lang.Object

Maintains a cache of Point objects for use in looking up things in maps. Rather than creating a new Point object for a lookup, call getPoint(x, y) to fetch a reference to a shared Point object. Just make sure never to change the (x) or (y) value for any of these points, or you'll get undefined results.
